How to remove/replace a fan clutch and water pump - bad water pump pulley - 4.2L Trailblazer
HTML-код
- Опубликовано: 14 окт 2024
- In this video I show you how I easily removed and replaced the fan clutch and water pump on my Chevrolet Trailblazer with the 4.2L 6-cylinder engine. The water pump bearing and pulley had a bad wobble. The bearing in the water pump was worn out. There was a loud squeaking noise coming from the water pump pulley...or so I thought.
Removing the fan clutch nut is fairly easy if you use a fan clutch wretch tool set. I rented one from Autozone for $100. Another step that helps speed up the process is "hacking" a small notch in the fan shroud to compensate for the radiator tube for the upper radiator hose. It's a bit of a hillbilly work-around, but hey, it works.
Overall, it seemed like a daunting task, but with the proper tools and a little ingenuity, the removal and replacement wasn't bad at all!

Im 23 and replaced almost everything in my car from youtube, and this was the most helpful video i found so i thank you internet hero's haha
4.5 Years after you made this video, some random stranger from Canada owes you a beer. I'm about to change my first water pump on my son's TB. Thank you for all your work, your edits and including torque spec's etc. Gonna check out the rest of your channel. Great work, you earned a sub!
Great video. About to do the same job. The lil comic reliefs in there were a great addition
I told myself right from the start of the video that was the idler. But you then made me second guess because you showed us the water pump pulley.
I’m glad I was right on my assumption. As well as I’m sure your glad the water pump pulley isn’t wobbling around anymore.
Just bought one of these for a grand with the same problem. Guy was just tired of messing with it I assume. After watching this, I feel like I stole it. Thank you, subbed.
Got my pump and rental tool for fan clutch.. I should have known. Advance auto rental tools absolutely suck. Nothing fits. Antifreeze drained, hose off, shroud loose and no way to return crap tools. Thank God for brothers with tools. I hope his fit.
SeeMooreVids hope so too!
Absolutely right about Advance Auto rental kit!!! Fit around 36mm nut is loose as shit... Will round of your nut!!! Kit should be yanked from the shelves!!!!
Thank you so much for your videos!!! That is exactly what is going on with my TB. ❤
Doing same job in reverse. Changed right side idler pulley, steak gone for three days. Then squeak returned and changed tensioner pulley squeak gone for two days. These idler pulleys were toast. Now squeak back and I found fan vibration. Changing pump this weekend. Yikes! Thanks for video. I can get ‘er done.
You got this!
Trial & error, helped my part swap easy breeze! Thanks for vid kid🤙
Thank you, just bought our third trailblazer and love them!
I'm a believer... thank you for the tips
I have done that job three times on my trailblazer. I use a big wrench and a piece of chain. Put the chain on the pump pully bolt and the other end to an engine bracket on the drivers side. No need to rent the tool
These are great!! The little funny comments are pure gold
Do u need the water pump gasket part? And do u have to use it on the gasket?
Great video. I was wondering about that tool because I've seen so many say that it was difficult to use.
BigDaddyDGraffix it wasn’t the easiest tool to use, but it got r dun
I tried that tool. Useless Ended up just using a pry bar to hold the pump pulley. Worked fine
Wanted to say thank you. About to do mine, and you made me aware to pay attention to the other pulleys,
Very well done...
Thank you for your service
it would be nice if you start some kind of series about repairing your silverado. I know it might have really high millage, tons of rust and stuff but i mean it's a cool vehicle, i think you would have fan and when you are done you would be pround of driving it around.
Can you tell me how long it took you to replace the fan clutch (roundabout…if I’m not doing the water pump as well)
Very helpful. Thank you
Thank you. Went really smooth after watching this.
Couldn't you take out the cross member bolts and pull it forwards to get the Fan Shroud past the radiator connector nasal? I'm getting ready to do this job myself on a 2004 Chevy Trailblazer. The Fan Clutch went bad so i'm going to replace the Fan Clutch and Water Pump at the same time. Right now i'm watching all the video's on how to do this job. Like your Video!! Tell me if you think that would work or not?
Good info, Thanks. I have an 03 Bravada and replaced the AC clutch bearing, which by the way seemed impossible to identify what bearing to use, but finally found the right one. Replacing the AC bearing is an entirely different story, but that way I did not need to have a shop drain the AC system, replace AC parts, etc. I loosened the crossmember bolts and I was able to remove the fan shroud without cutting the shroud.
A lot of people simply replace the tensioner and that pully anyway once you have everything open, assuming you have no idea how old the existing one is. If you don't do that you can release the belt and hand turn the AC, pulleys, etc and usually you can hear a noise or feel the bearing is dragging. So that means it needs to be replaced.
This was a super helpful video! Much appreciated
Not much movement in the fan or pully. But the fan and pully are crooked as hell. Could the water pump still be bad? 2003 Chevy trailblazer. Got these pictures.
Mine just started to do that. How long did you drive it like this before you changed it?
Not terribly long, however the previous owner likely drove it that way for thousands of miles.
@@TheDaninator mine broke after 2 days
Nice man thx for the info! About to tear into mine now..cool extra clips through out the video too lmao
Earned a like and a subscribe. Great work. Made it look easy. I work on these all the time so I know they aren't always that easy. Much love. Thanks for the video.
Missnewgen thank you
@@TheDaninator Got her done this morning before work. took longer because hubby was running to part stores this morning while I took everything apart. Yes I'm a mechanic and so is he. Just never had the pleasure of swapping this particular part on any vehicle. All went well and she's back on the road for my 80 miles per day to and from work. Glad this happened over the weekend. Thanks again.
Glad you got it fixed!
I think your channel has good content. I subscribed.
Thank you
Nice job. Thanks., Exact prob I was having.
That shroud is no joke. Now I see why them "backyard" mechanics didn't put my fan shroud back on after they installed my engine.
Top notch video! Thank you!
Do yoy know the kit # by any chance? Just called up AutoZone and asked for this kit and the guy didn't know what it was... Blows my mind.
Right on brother 💪💪💪
What socket did he use to loosen the belt
Why does the fan blade itself have a ring/shroud around it? I've been wondering this shit for years, the Chevy trucks have the same similar fan blade without the ring.
Brother u explained and showed the tools and symptoms my tb has @ fan slapping shroud.. this vid deserves a lot more views
king nasty thanks man. Glad the vid was helpful!
Any advice for stuck clutch nut..? Tried couldn't get off
king nasty are u using the clutch nut wrench tool? If not I’ve seen guys bolt a chain to the water pump pulley to keep it still and then use a big wrench like a pipe wrench or something
i need to replace my water pump , i don't hear any squealing noises though so does that mean my water pump pulley is still good?
You did a great job on this repair! Thank you again for the video
Another great video! Good job!
Great vid, I use the chain method.
Anyways, you didn't use dex Cool?
Green coolant can be used in place of dex cool as long as you are not mixing the two together, its really just a preference
Hey @The Daninator very much thx for the vid and greetings from Germany. 😀
Guy what is this pulley called that finaly made that noise?
Greetings! I believe the pulley is called an idler pulley
@@TheDaninator thx a lot!
My water pump pulley shakes really bad like it's going to come off. What should I do?
Do i have to unplug the battery or is it just a precaution
Unplugging the battery is good insurance that nothing electrical goes screwy when you're unplugging connectors or working around unplugged connectors.
Great video… not bad for an amateur. :P
Definitely would have just drained all the radiator fluid from the beginning, eh?
Thanks again. Good for another 100k miles, eh? :P
In total, how much time did the job take for you?
Hey Brandon does
A 05Jeep Grand Cherokee Lareado have two fan blades? One on the engine and one onext to the radiator?????
DO IT!!! JUST DO IT!!!!!! 😂
is the nut 36mm?
How the hell did you just drop the fan shroud in there like that, with the fan clutch attached too?
I'm having a nightmare trying to get mine back in....lol
Cutting the notch in the shroud helped. It just slid down into place.
@@TheDaninator Yeah, that does help and that's what I did. Broke out the almighty dremel.
Ive done this job to my wifes, and just had a flashback, I pinched the top radiator hose clamp, and when I went to slide with my fingers(DO NOT DO THIS!) it sprung, and hurt very bad lol
That stuff is not the same as Dex-Cool which is what you need for the Trailblazer. It requires Dex-Cool !
Dex-Cool stinks. The old green coolant is better and lasts longer.
I replaced mine a long time ago after I had gasket issues.
Ditched the Dex Cool years ago and flushed system. Refilled with Prestone
Epic video
The LEADING CAUSE of water pump FAILURE is the design of the fan clutch, it's WAY TOO HEAVY and it CAUSES bearing FAILURE. my 97 Silverado fan clutch will fit the water pump pump but the check engine light will come on due to the fact the trailblazer is wired from the factory.
Everyone makes this common mistake,does anyone realize that the Radiator is clamped down on top with 2 13mm bolts and 2 bolts going horizontally through the plastic bracket can’t remember what size but they’re small,after getting the bracket off just simply bend the Radiator towards the front and easily slide out your fanshroud ,making sure you to take the trans lines off your shroud,
As a side note,a Waterpump will never squeak as the bearing is always lubricated by the cooling,looks like even though that wasnt the problem the waterpump was on its final days,99 % of the time the squeak is the Idler or tensioner pulley,both should be replaced at the same time,sometimes you can get a squeaky Alternator ,that’s usually also right before it dies
😊
go tribe!
So u didn't change the pully. Or clutch fan
The Radiator, fan guard fan comes out all as one piece.
My name is Diane Dodd's i need to buy a 2002 radiator do you have one im going on amazon to find one for $40 or a little more i had a truck accident my hood not bent on out side but bent on in side it wont you to send a front and side vinder. call me at 662370 0131 address write 1806 10 th ave n. Columbus ms 28701.
Bro I needed the size of the bolts to fan blade on the clutch and you cheated me. By cutting the shroud. Wth
13mm
If I had to hear it called a clutch fan one more time.
...clutch fan. Lol
A gasket and rtv she definitely wont leak 😂
It’s DEX coolant only 🤦♂️
If you completely swap the coolant the green can be used if preferred you just cant mix the two together
