I am an ASE master tech w/L1 advanced tech w/over 40 yrs exp so i can tell you listen to this guy the way he explains in this video work easy with or without the engine in the vehicle. Don't be intimidated by this engine. like women It's easy after your first. Great vid young buck, keep it up , your the future
It can be done in the car I I did it changed timing chain in the car
Yeah - I got over 500,000Km from my 3.6 alloytech. They aren't a difficult engine if you are used to euros... Only put the car to the scrappers because of serious cracking.
Do you prime the oil pump before installation???
@@mky9227 Hek yes... If you've taken the housing off - or you are using new years (smrt idea) just pack some grease in the housing first. You can't get neg pressure and the pumps leak like a mofo.
The standard grease will be lost in the oil. You'll be changing oil out after a few weeks - so it's not a concern.
@mky9227 anytime u still pump prime with oil to get air out
My name is James. I have a 2009 Cadillac CTS with a 3.6. I watched your video and followed step by step procedures on how to replace my timing chains. It was so very helpful as I had not installed one on overhead cams before. I would highly recommend your video to anyone that attempts to do the chains for themselves. Thank you very much!!!
Though Ive done a few 3.6l chains, I by no means remember every signal mark or step. Mike is absolutely correct about service info not having a signal spot to get all the steps from. its broken down into every piece , guide and sprocket. Having a video that goes through step by step insures not missing a mark on a very labor intensive job! Great work Mike!
Hands down, The best automotive repair tutorial and content ever
Thanks man!

Good overall video on doing the timing chains on these GM 3.6 l
One critical piece of information though before you even start the job.
If you're attempting to do this with the motor still in which I have done many many many times for front wheel drive vehicles such as the Arcadia traverse terrain and Buick and even some old Saturns that use this motor
The hardest part of the entire job can be just getting the effing crank pulley off. A lot of people grind down modify a three jaw puller
From places such as harbor freight but there's not a whole lot of clearance between the frame rail where the crank pulley sits
Get yourself the OEM GM or good eBay knock off crank pulley remover tool for this motor. It's not a three jaw puller it's a one piece design that slips perfectly over the crank pulley on these gm3.6 motors giving you the clearance you need Or you'll never even be able to start to get your timing chains off because you won't be able to pull the timing chain cover or anything else you will quit before you even start just trying to get the damn crank pulley off if you don't have the proper tool.
Other side notes go with the cloyes timing chain kit spend the 400 bucks for the love of God there are lots of $200 Chinese timing chain kits for sale on eBay and Amazon everyone ive helped do one of these 3.6 motors with the Chinese kits the timing chain tensioners and other components always fail within a year
You are not saving a couple bucks by going with cheap parts. You'll be doing the job again prematurely.
Other notes would include this is an interference engine. If your cam phasers go bad if you're lucky the motor will just click
But if this does jump out of time you will bend valves and if that happens of course you replacing valves by removing the heads
You're also looking at replacing the cam phasers that's another part do not go aftermarket on there's lots of Chinese knockoffs on Amazon and eBay they only cost about $20 more a piece for the OEM GM cam phasers did make the note in this video which I've seen people miss
Both left and right bank exhaust cam phasers are the same same GM part number
But I've worked on 3.6l that are still throwing codes because people don't realize when changing the intake phasers there are separate part numbers there is a left and a right intake when lining up your timing chain marks
Up top on the phasers when your cams are flat as he explains in the video you have a little circle and a triangle on the phasers
One way to tell if you have it right is you should have 12 links between the exhaust and intake phaser on each Bank
You can think you have it right assemble the whole vehicle it will start and it will run but after it warms up in the O2 sensors kick on and starts talking to the computer and running efficiently it'll start throwing codes
Because your cam phasers or not installed correctly as in you ordered a cheap eBay intake phasers I sent you two of the same model number I've seen this happen many times not realizing there's a left bank right Bank intake phaser and the vehicle will run but not right and throw codes.
It's not an overly complex hard job to do
Just make sure you have every correct part and it's a quality part before you attempt this job.
And one last very very very very important part for the do-it-yourselfer attempting this with oil pump replacement do not immediately when completing this job fire your vehicle up these GM 3.6 l they need a minute or two of cranking to prime correctly when you're completely done with the job leave the spark plugs out and make sure on the under the hood fuse panel you pull the fuel pump fuse verified I don't even hook the fuel line up to the fuel rail so when the keys in the on position nothing is being pumped from the tank up to the motor then crank the vehicle over when the mentioned above is verified I start with 5 seconds of cranking and let the vehicle sit for about half a minute
Then I'll continue cranking for 10 seconds let it sit for another half a minute all the way till I crank it till about 15 to 20 seconds just to make damn sure the new pump is primed and has sent oil all the way from the bottom of the pan up through the heads lubing up the phasers in the Cam's good in the hydraulic timing chain tensioners before finally dropping the spark plugs back in popping back in the fuel pump fuse and finally allowing the vehicle to start then you won't have any clicking or knocking noise because the vehicle's been oil primed well.
I mention this comment because one of the first traverses I worked on with the stretch timing chain issue and the oil pump changed and everything was done correctly but not properly primed newly installed oil pump
And the vehicle ran dry for the first couple seconds which was enough to actually score the crank bearings on this gm 3.6 engine
As with all engines especially this one some are more tolerant than others quality oil and oil pressure are everything to this engine
I firmly believe half the timing chain stretch issues are related to this motor because people do not do enough oil changes gunking this GM 3.6 l motor up. And piss poor GM engineering on the right Bank crankcase ventilation system on this engine.
This can be a
Very good quality engine as long as you keep them clean a $50 full synthetic oil change every 6 months or 5,000 miles this engine easily make it to 200k Plus trying to skip oil changes driving 10 to 20K miles between oil changes and I've seen these motors grenade before they reach the 100K mark.
And the very very last note
People don't realize GM had a problem with this vehicle when it's throwing codes
Saying the timings off and a vehicle is not making any clicking or rattling noises ie everything is nice and tight the way it should be the earlier year GM 3.6 l I believe it was the 2007 models the pulse ring which is a gear that is pressed onto the back of the crankshaft again was only pressed on from the factory and not welded and what happens is after a period of time certain 3.6 l motors because they were not welded onto the crank but only press fit pulse ring tone gear different people call them different things is what your crankshaft position sensor on the back of the motor reads to send a signal to the computer to make sure everything's timed and firing right if you are unfortunate enough to have one of these tone rings that slips in the crankshaft no amount of timing chains and switching sensors will fix it the only thing that does it is changing the crankshaft out which the labor involved it's normally cheaper just to get a new motor. Not a common problem but one that has been documented with this 3.6 l motor. And is one of the causes of the dreaded check engine light timing is not with in tolerance code.
@Aaron Wildman, are you referring part# 25264 for the pulley/HB tool? Thanks in advance
I purchased a 2011 Chevrolet Traverse new. I changed oil at 75% to 90% of the oil indicator. I used oil specified by GM. API rating, oil weight and Dexos rated. Mostly Mobile 1. I used GM oil the first couple of years, as Dexos rated oil was difficult to find. I gave my Traverse to my sister in 2022 with 180,000 miles. My sister is still driving it. Has about 200,000 miles. Original timing chains. I was careful about oil changes and followed GM’s specifications. I made sure crankcase breathing system was operating correctly and oil level was maintained. It did not consume oil. Worked out for me. YMMV.
just done my 4th timing chain on one of these 3.6s, always come back to this video, very well constructed and understandable
Never thought I'd be doing this but here I am now.
I have been looking for a detailed video for how to do this for literally years, thank you for making it.
And thank you for watching and commenting :)
Mike Becker, Senior Instructor
Agreed
Thanks so much for taking the time to put this together. This has to be one of the best how to videos I've seen.
Thanks for watching!
Mike Becker, Senior Instructor
Totally agree with you CHEERS
It is the only video that explains steps 1 and 2.patiently. I understood the procedures of timing very easily. Thanks so much!
Amazing job, appreciate how thorough and professional you are.
I have done several of these engines timing chains. If you use the special tools on all 4 cams at once, You do NOT have to rotate the engine to phase 2 etc at all. Simply install tools and remove all the timing chains at once way easier then doing this turning over the engine part, The special tools are actually cheap. They keep everything locked down and in correct position. The Camaro 3.6 timing chains can be done in the car, while on Acadia/traverse/Srx 3.0/3.6 I simply removed the engine and transmission out the bottom and did it on the ground way easier and less fighting. Using a lift of course.
I agree the rear wheel drive vehicles make this job much less of a task.
I will have to look into getting our shop a set of these special tools.
Ryan W, Technical Instructor
not using the cam tools . does the flats of the cams line up perfect? mine seem to be off slightly. is this normal or do you think I have a secondary problem I need to find?
@@riseandswinefarm7522 the tools slide onto the oblong part at the back of the cams. you can use the timing marks on the cam gears to verify correct position though. the chains have colored links that link up with the dots on the cam gears.
2
Even with the tools you have to put engine in stage 2 timing the kit comes with 3 tools for exactly that
Yeah, definitely one of the best to follow. Did my 2008 CTS4 LLT engine using mostly this guide, even had factory manual, but this was THE guide for me. So thank you very much!
Thank you very much for this excellent video. Mike, you are not only a master technician but also a master teacher! Appreciate that very much.
Greetings from Bavaria/Germany 👍
Mike , I just did my first timing chain job I viewed several other videos before finding yours and in those other videos they don't have what you have your a damn good instructor you explained different scenarios perfectly you have taught me a lot I can't thank you enough, im a OSHA Investigator /Safety Trainer / Instructor myself you have a good way of getting your audience attention your gonna go along way in your career Sir it has been an honor to learn from you I sincerely mean you did an awesome job.Best wishes to you and yours thanks Mike
Very excellent video out of all of my watch. This is the only one that is complete. And a great thanks to the guy who did the Presentation. Very professional.
Just wanna say this helped me so much, and I'm a GM dealership technician. Helped out so much more than Service Information did. Followed this and got it right the first time. So with that said, thanks so much for making this video!
Hello,
Thanks for the kind words.
I agree, Service information is hard to follow. They split it up too much and make it impossible to use without switching screens constantly. Actually part of the reason it was decided to make this video!
Glad it helped you and thanks for reaching out
Ryan Wilsing
And you are a crooked union criminal that just towels the job.
What was the mileage on this motor
Thanks so much for taking the time to properly explain the process, I was a bit scared thinking about doing the process myself, thanks to your video I feel a bit more confident on how to properly repair the timing chains on my 3.6l Pontiac G8
Glad it was helpful! Thanks for watching
Ryan W, Technical Instructor
Have watched over a dozen different videos on this…even a couple from the big names making the kits…this is THE BEST and most thorough video i have found…THANK YOU!!!
Amazing video! Using this to repair a Holden VZ Commodore, you've gone over a lot of things that the Australian tutorials haven't.
I appreciate all the work you put into these videos.
Thanks
Thanks so much Kevin!

Mike, A+ Presentation. Your are clearly an expert who worked hard to know what you know! 👍
Aww thanks Mark! Appreciate it :)
Mike Becker, Senior Instructor
I bought the cloyes kit from summit racing but I used this video to install the timing chain kit because there is a whole lot more information than the cloyes instructional video. Your video is more real world scenario in my opinion.
I feel the same way
NO WONDER WHY 3.6 HAVE TIMING ISUES.
IF YOU CAN'T MATCH TIMING MARKS ON SECOND SPIN ,
THERE'S A PROBLEM WITH THAT ENGINE AND THE BIG REASON WHY STRETCHED CHAINS. (ITS NOT THE OIL LIKE GM SAYS)
IT MAKES SENSE.
SUV'S WITH THAT ENGINE ARE FROM $1000 TO $3000

YOU DID A GREAT JOB EXPLAINING STEP BY STEP. 👍
FIRST OF ALL ENGINES W/ ( ONE) TIMING CHAIN HAVE RAN TWO - THREE HUNDRED THOUSAND MILE W/out ANY PROBLEMS FOR YEARS UNTIL THEY CAME OUT W/ THESE THREE - FOUR TIMING CHAIN SHIT THEY MAKE TODAY JUST MORE SHIT TO WEAR OUT.
@@garythomas2124Toyota has a 3.5 V6 with the same 4 cam design. They don't have any issues because Toyota uses a better design. GM tried to make the timing chain cheaper because it still outlasts the warranty anyway.
Really excellent video help, I do admit that the dot marks and the triangle’s were confusing me as to which ones to use to line up the chain’s, but when when I watched the entire video it became perfectly clear to me. I have always been mechanically inclined when it came to taking things apart and then putting them back together, but I haven’t changed a set of chains and an oil pump in many many many years .The oil pump was the easy part I must say. I should mention I did this with the engine in the car not out, a 2010 Camaro, with out the help of this video I wouldn’t have been able to do it. Thank you for that. I turned 65 this year and I have very limited funds ,so I end up doing almost all of my own repairs. Can’t afford the labour rates at most garage’s. Last time I had the crank replaced because of bad rod Bering it cost over $5000.00 at a GM dealer and it was never did run right after they were done, they wouldn’t give me an exact price for the work, had I known how much it was going to cost I would have picked up a new motor. Can’t trust most Garage’s. And by the way, it was just out of factory warranty by 500 Kilometres. Yes i am Canadian.
Hey Steve,
Nice Work! Glad you got it fixed!
Thanks for watching
~Ryan Wilsing
So you figured out the triangles where the marks also? Lol I had the same issues when I did it ….by the way I did my 3.6 vvt with the engine still in car 💪
Well Done, Thank You. No wasted verbiage, just great explanation of what to do. Now to be able to do this 1/2 blind while the engine is in the car. Glad Melling recognized your talent and provided quality parts for you.
Thanks for watching Mr McD!
Mike Becker, Senior Instructor
Wait this can be done with the engine still in the car or are you being sarcastic. Just wondering because I have a 09 traverse with 170000 miles not sure but think I have a burnt valve ,ero compression on number 4
Can be done in the car 100%
@@jacobmorse3280 Yes, it can be done, very tedious job, not easy and not a lot of room. I took my car fully apart, removed the timing, bought the $1,000 in parts to fix it but before starting the install I was cleaning and I put a magnet into my oil pan and came out with a Rod Bearing half. Not good, at this point I knew I needed a full overhaul. I purchased the car broken, the owner told me it needed a timing chain. He was wrong. The crankshaft was damaged. Parts and machine shop work were over $2,000, I found an engine with 34K miles on it and bought and installed it. The timing could have been done but not the full overhaul in the car. At 170K miles if you have not cleaned your valves they probably have carbon build up choking off your intake air flow. I have cleaned 2 engines now both at around 120,000 and the build up was substantial.
@@mrmcd5728how should I go about cleaning my valves?
Done several Acadia, Traverse timing chain replacements and your video is spot on. I take off the bumper, radiator, etc and pull motor from the top. Tedious but isn't difficult.
Thank you so much.. I followed this video as I fitted the cam chain set and glad to say she's purring like a kitten... Cheers from Melbourne down under.
Great video! You did an awesome job buddy! Extremely thorough on your descriptions including part names, placements, order/run sequence and especially the step by step in depth direction. Would be very easy for someone with little to no experience to use as a guide as I found out first hand just how easy it would be.id most definitely recommend this video to newbie mechanics and also old timers if they are needing some guidance or know how. Subscribe to this man and help him make more videos for folks like you and I. ( One recommendation I'd like to make to the gentleman responsible for creating the video would be to use a more visible color to mark out the timing marks and set position. I know it's probably very visible in person but for us watching the video the yellow is very hard to recognize. I've found white to work rather good from start to finish.)
Hey Shane,
Thanks for the kind words and supporting our channel!
We will definitely give white a shot next time and see how it turns out!

This is an extremely well done and informative video on performing the replacement of the timing components on the GM 3.6 engine. Thank you!
Thanks so much Timothy!

Thank you so much for taking the time to make this video. I've done timing chains in all kinds of things but never a 3.6 gm.........this video is extremely thorough and informative and most definitely helped me out!
this video has really helped me get my daughters Saturn Outlook back on the road! Well done, easy to understand, very informative. THANKS!!
I've tried to count on several different engines....ALWAYS lose my count. You just basically spin for about 10 minutes straight LOL...awesome video sir.

@@GoTechTrainingis there any kind of snake oil that will make this last a little longer
This is better than the cloyes video there’s some helpful tips on aligning
Thanks for the tutorial! My son just purchased a 2011 Traverse that has a misfire issue. We've changed plugs and coils and checked the cats, with no resolve. Our next adventure is going to be pulling the engine and doing a complete rebuild. I'm feeling a whole lot more confident about taking this job on now. 😊
Excellent video as always Mike. Thanks for making a detailed video for this job. It's really how confusing it is in SI that gets um 😉
How long does it take to change a timer
Hi Mike. Great video. Thanks. Recently did a 2012 Audi 2.0. I've done old American cars with a single chain before. This was a new experience for me. I wasn't sure how long it took for oil to start to lube the chains, so; I placed the chains in motor oil an let them drip off before installing. I figured that it wouldn't hurt, and maybe helped get oil into the chain links and pins. There was nothing in factory service data about this. All went fine.
If you unplug the crankshaft position sensor and turn it over a few times it will pre lube the engine. With the sensor unplugged there is no spark or fuel sent to the engine.
@@DarrelllCampbelll Great. Thanks.
@@DarrelllCampbelll
Are you aware of what “clear flood mode” is by any chance?
If you don’t, it is the ability of the ECU to not fire the injectors when cranking the engine if you have WOT, obviously to start a flooded engine. Very handy after an oil change to fill the filter before it fires up.
Careful, not all cars have it so try it before you need it. Also good to scare the wife when you are far away from home. 😇
This has got to be the best video hands down! It just made me $700 😅 friends and family discount.
Thank you. I couldn't find any info on timing marks to remove chains. Your video was exactly what I needed.
Glad that it helped you! Hope you got your vehicle fixed!

You gotta give it gm. The 3.6 with the timing chains and the 2.4 with oil consumption, vvt, timing chains?, And water pumps. What an incredible decade for techs.
What a time to be alive Bobby! I bet warranty repair time on these engines is HORRIBLE though.
Mike Becker, Senior Insturctor
The water pump thing is been going on since the 70’s. Some people never learn….☺️
As a tech, the 3.6L is an absolute nightmare every time. No one likes doing them here.
@@GoTechTraining When I worked heavy line for Ford in the early 90s, the engineers told us that all labor times for warranty repairs were set with technicians in Detroit using hand tools. What a load of crap!
Almost all of the 5.0 engines we would pull apart would have every ring Gap lined up perfect in a row.
I used to say that they need to hire a monkey on meth to spend the piston rings before they slide them in the cylinder. Would have been much better.
LOL
They also horrendous piston slap when cold. They would usually have .009 to .010 piston to cylinder wall clearance from the factory.
Instead of making a better product, they just lowered the warranty from 6-year 60,000 mi to 5 year 50,000 MI. They should have just fixed it right on the assembly line.
Hey yes job appears intimidating especially an engine needing 3 timing chains. Excellent tutorial
Thanks Heaps I'm going to do it ,I had an accident and broke my back and now I'm an incomplete paraplegic it's been since early 2013 and now I'm back at work doing registration checks for cars as they have to pass every year to be on the road, I've never done a timming chain in these an you have given me great conference on doing this job as my young bloke has just bought his first car and it needs this done , I can follow your instructions easley ,awsome video, Thanks for Australia
nice work mike! you make look easy melling is a good aftermarket i would use those old chains had some wear! remember the quad 4 those chains never had a problem i had left the dealer in 09 so i missed the fun.... im independent now but havent done one yet
Hey Scuba, thanks for watching! Yeh, the Melling stuff seems good. Not a bad job overall if you end up with one.

great video, just got a 3.6 and the timing was already torn apart for heads, it shall be interesting to get it back in time, im sure with this video i should be able to get it all back in time! very well presented! this is no easy timing set up by all means.
Thank you Mike. Even at the factory level those engineers have nothing over you.

Let me correct that Philly, Make all GM engine pushrod again. They excell at it. Many other brands do pretty well with DOHC motors.

Watched the video step by step and i love it, thank you so much for this video, you deserve a raise and God bless you !!!
alright mike, just wanna say a job well done, it's always stress releasing when seeing someone doing a job both graciously and logically. though i'm more of a motorcycle mechanic, but i still learn a lot from your videos.
out of curiosity, maybe it's my ocd kicking in, but is there a reason that loctite was not applied on the secondary sprocket and chain tensioner guide, or even the tensioner mounting bolt? i tend to put loctite on the moving parts mounting bolts, cos i've seen those bolts came off, and it wasn't pretty.
cheers, fan from Taiwan
Nels
Hey Nels, thanks for watching! So, if the bolts had loctite from the factory, I would have put it on there. But, they did not, so I simply torque them to spec and trust that the service information is correct :)
Mike Becker, Senior Instructor
Great video, really appreciate the details. Quick question what type of markers did you use to mark the timing.
Looks like paint markers
THIS IS THE BEST INSTRUCTIONAL CLIP EVER!!
Awesomeness... Just like that, our engine is in time👍
Seems like a great engine on paper and when it works, but a few local shops hate them because of the chain issues. I still have a Chevrolet Uplander with the 3.9 and 240,000 miles, no oil burning and it's been a great engine so far, but it regularly likes to develop small oil leaks like a BMW which is annoying lol
Hey Jeremy, I don't think the 3.6L would be so bad if people would have just changed oil on them!
Mike Becker, Senior Insturctor
@@GoTechTraining I've read that too and hopefully it's true, but unless it had super low miles with warranty or someone has regular oil change interval proof from the beginning, I don't think I'd ever feel comfortable buying one secondhand.
Yeh, I feel you on that one. I was not "impressed" when I opened up this used one. She wasn't pretty inside.
Mike Becker, Senior Insturctor
3.9 will out last a 3.6 even with staying up with maintenance
I've done a gazzilion of these of these. G.M. wants you to bring it to Stage 1 then disassemble,that way when you put left side chain on and secondary you only have to rotate crank from 5 o'clock mark to 8 o'clock, a few degrees. That is an interference engine you do not want to rotate crank 360 with cams out of phase
Hey John, thanks for watching! That makes sense. I maybe missed that part in the riduculously hard to interpret procedure. Fortunately, nothing bad seems to occour if you do bring it around over 360°.
Mike Becker, Senior Instructor
@@GoTechTraining @GoTech That is good that you did not bend any valves,had lots towed into the shop where the cams came out of phase and bent lots of valves! Would not make a habit of it usually a death sentence for these older vehicles haha.

Mike's way of disconnecting the right bank, then turning the left with the crank works too, but for sure you have to make notes and not get confused.

Glad you mentioned to Replace oil Pump as most people I've done that job for don't think it is necessary then I have a argument over it I wouldn't do the job if it wasn't Replaced, oh yea and Replace Water Pump..
Hey Paul, thanks for watching! Sure, the waterpump could/should be replaced right away too. Why not, you're already there :)
Mike Becker, Senior Instructor
Just wondering why did he not have to turn crank 360 deg. to get into Phase 2 timing?
Well, if someone brings one of those over, they will not be happy when I say I'm not going to attack that without the engine being pulled.
I can't imagine attempting that job in the vehicle.
Hey Emmett, thanks for watching! I couldn't imagine doing that job in the car. There's such little clearance.
Mike Becker, Senior Insturctor
not worth the parts an labor cost anyway ;)
best bets is slam a whole reman engine in or get a different vehicle, unless you're a mechanic and can handle everything yourself!
planned obsolescence, Billary Clinton and Obama following the "save the planet green noise".. yes because saving the planet with green junk reduces end pollution slightly whilst producing massive volumes more of waste and energy usage from massive amounts of production, handling and waste.
why cannot anyone see the big picture? especially the government sheeple, which need flushed out hard
Doing this for the second time in the vehicle right now. It iss not fun at all. I tried to get a shop to do it this time and no one would even touch it.
@@roscopsoultrain5875 i know how you feel. With my limited knowledge, it took 5 hours just to get the valve covers off and another 5 to get the engine cover off. Good luck!

At 6.50 are the flats of the camshafts showing unusual wear? What is the service life of these chain sets in your experience? Any idea of the mileage of the donor engine? I enjoy your quiet competence and through presentation. I am able to transfer these attitudes displayed to dissimilar projects.
Thanks for another good video.
Hey Xombi Xombi, thanks for watching! I'm not sure on wear on the flats, but the cams were very dirty. This used engine didn't have the best oil change intervals I don't think. That used motor had about 120K on it with original chains.

Hi Guys, great video thanks, I've read this elsewhere "Once assembled, the timing chain tensioners need to be fully released to maintain adequate tension. Simply pulling the pins is not enough. All tensioners must be pressed in by hand for the internal mechanism to fully pop out and operate effectively". Should this have to happen?
Cheers
Gibbo
Hey Gibbo, thanks for watching! Interesting, I haven't heard that. There's nothing in the procedure about it.
Mike Becker, Senior Instructor
@@GoTechTraining Hi Mike, Great video. Haynes online shows using a flathead screwdriver to twist the tensioner spring up into the tube and it locks. You can leave it there and hit it with the guide and it will pop out, like with the Primary Chain Tensioner - it doesn't have a hole for a lock pin, but the others do and you can put a paper clip in the hole and pull it when the chain looks correct on the marks. I "retimed" a 2012 Traverse 3.6 with old chains to see if I could get the engine to pass a leak down test and while following your video, I found that the Primary Chain had jumped/stretched a tooth. Things got happy once the chains were in time and the leak test was good. Then, knowing the internals were mostly OK, I purchased a new chain set including Phasers, Oil Pump, Water Pump, Thermostat, etc... and she's very happy. Not bad for a $400 dead Traverse and a lot of labor from a 74 year old enthusiast mechanic. Enjoying the ride now. Thanks!
I want to say thank you for this video it should help me a lot on reassembling or doing this engine that I've got I hired a mechanic that screwed it up and I was a waste of money having him do it I shouldn't I knew I should have done it on my own but thanks to you I will go ahead and do it on my own I just got my fingers crossed that we didn't punch a hole in the piston so next week I ordered head gasket kit the timing tools that you recommended and then I went ahead and ordered a new oil pump so hopefully next weekend I will be busy putting this thing tearing it apart and putting it back together hopefully with your video I will be able to put the thing back together correctly although I will say that I'm going to be doing it with the engine in the engine bay as I don't have the equipment to pull the front clip out so to speak so wish me luck God willing I will do the job right the first time and it will run just fine.
Best training session ive seen . Very good job
Awesome video with lots if information. Will this apply to a 2010 camaro LT?
Hey Luis, thanks for watching! Yeh, I believe the 3.6L in the Camaro has the same set up.
Mike Becker, Senior Instructor
Is there a o-ring that goes between the oil pump & the block ? I noticed a recessed area on the oil pump where it looks like an o-ring should go.
Hey Dwayne, no there is no o-ring between there. I was a little shocked by that when I put it in!
Mike Becker, Senior Instructor
Wow, this was a really infomrative video. I've seen several of these timing chain videos and have learned from each but this video has the greateset level of detail, plus the oil pump replacement makes me feel more comfortable about tackling that as well. Can't wait to get started. Thank you very much for the video!
Woah Andy thanks so much, what a compliment! Thanks for watching and good luck with the job!

Thank you for this video. Much more descriptive than Pro-demand and All-data
Thanks for watching! Yeh, I wasn't thrilled about the way Alldata and GM lay it out. its super confusing for sure.
~Mike
Thank you once more Mike. So this is a non-interference engine? Apparently you turned the crank more than one revolution to put it into stage one position with the right side secondary chain off,
Hey Juergen, that's a good point. I didn't even think about that. Hmmm...I have heard of these engines bending valves though. Insteresting.
Mike Becker, Senior Insturctor
This is a interference engine and has very small valve stems, they will bend with minimal force. This is why the phasers only have 12° of ± variance. the later years only have one set point. There is a set tool "key" guide for the back of the camshafts. This is a A level tech job.
There is reliefs on the pistons as long as you don't let a camshaft snap hard while rotating camshafts manually with 20mm wrench on hex feature and 16mm socket on camshaft bolt; clockwise, you will want to begin rotating camshaft by its bolt 50% into spring load and then grab low on the hex feature with wrench to transfer tension load from socket to wrench against springs and not let it snap forward. Slowly rotating it clockwise with the 20mm wrench; gently landing it, while having enough room to grab it low enough on hex so you have full rotation without smashing hands after rotating so the flats are facing upward.
@@DevJB so what does he do now
@@GoTechTraining are the timing chains on a 3 litre V6 the same as a 3.6 litre
The whole job can be done from stage 2 timing position. Just set stage 2 as shown here, then remove all chains, and replace. the cams and crank won't be moved, so it can't be incorrect.
hey mate have u done it in stage 2
@@user-dz2jd2pz1g yeah, it's how I do all of mine. Never had an issue.
@@Knackersjewels do you have any instructions...we did ours but ended up with a rattle from RH side when we started car...stripped down again and the chain tensioner is not working properly
@@Darrylmc63 did you use an aftermarket kit, or a genuine GM one? I've had a few customer supplied aftermarket kits where the tensioners are DOA
@@Knackersjewels aftermarket one unfortunately
Really enjoyed this video. So much more useful information, than the Cloyes video, trying to describe the same thing. You show us what we can run into while servicing our chains, and how to solve it. Excellent job Mike!!
Hey Greg, thanks so much! I appreciate the kind words :)
Mike Becker, Senior Instructor
great job i watched the meling video first and it just left me confused they didnt give enough details. your video cleared everything up thanks great job
Awesome, thank you for reaching out!

To think that GM canceled the 3800 for that abomination.
Ohhhh Wayne, I miss the 3.8L. I owned many of them!
Mike Becker, Senior Instructor
That's why I am keeping my Dodge minivan with the 3.8 and avoiding the 3.6 I am guessing that Chrysler and GM engines are a different version of the same engine concept?
The first series 3800s were an abomination, as a master auto tech 46 years experience, Gm has made garbage than any 5 car companies combined
This guy is nuts I would never put an oil pump on an engine without priming it with Vaseline
And people wonder why some repairs cost so much, it's a tough job and you was great 👍
Thanks for watching!
Mike Becker, Senior Instructor
Nice job! Always great to get those aftermarket parts. Much better than the GM company parts.
Great video man. I have one im doing right now and the rear bank lost its chain. Thanks to your video and being so in depth with it, i was able to work backwards and make sure my crank was in correct position to get the timing in with out having to guess and spin the motor over a hundred times to verify correct timing
Hi Billy,
Glad you like the video and it helped you on a repair!
Thanks for reaching out!
~Ryan Wilsing
When it Lost it's chain Did it warp any valves or do any head damage
this video is absolutely amazing, thank you so much
One of the best video I have. Seen here...👍👍
Thanks man! Excellent video! Helped me a lot!
Great video - probably easier to do than explain so many thanks !!
Well explained, great job mate.🙂👍
Thank you Mike. I will save this lesson. I appreciate the lesson.
Hey L j, thanks a ton for watching!
Mike Becker, Senior Insturctor
Best video out there on this topic
Best video on doing this task as simply as possible. Explained so even I can understand it. Thank you very much A+++
Hey Mark, thanks soooo much! Glad you loved it!
~Mike
This is the most detailed video
Great video, i will watch more of his clips.
Thank you for the time for explanation of the time belt position and installation procedure, best video washing about timing 👌 Thank you so much for your time, and God bless you.
Hi Juan,
Thank you for watching.
Ryan W Technical Instructor
Awesome 👍 video and great info. Just did my chains on a 2009 Acadia. I’ll post up if it runs after I get it together. 😂
in case you were wondering 1 484 392 rotations to line the marks up to the gears
you are so meticulous, awesome tutorial. thank you
Thanks. You convinced me to keep my 3.5 impala. No 3.6 ever.
Excellent video ! Thanks for sharing
Thanks for breaking down what could be an overwhelming project!
Hey Eric, thanks for watching!
Mike Becker, Senior Instructor
Hello Mike, a couple of questions. I have a 2008 Cadillac SRX with the 3.6 V6--I assume this is the same engine? Have you ever done this timing chain swap with the engine IN the vehicle? I plan to remove/replace the radiator and water pump anyway, so I assume access would be okay? Or would it make sense to remove the front bumper cover/grille, as well? Looks like a job that you need good access for.
