Awesome work very thorough not sure why viewers accuse you for not being honest about your findings any good tech would take these steps with little variation. Good stuff thx for taking the time to share your knowledge.
A couple things. First off, you are killing it in these pulse sensor videos. Two. WHY are manufacturers still using plastic on cooling systems! They become so brittle. Im glad the engine was too hot. That could have hurt.
Great video brother, You know you got my vote on the contest. Always a pleasure watching your work! As for the coolant hose, well chalk that up to bad luck. Customer should be happy it didn't happen on the road...it sure wasn't going much further.
Love how u keep real , we all saw it was that crappy design that failed on that coolant fitting I can already tell am going to watch this video several times ITS THAT GOOD 👍👍👍
Great video Mario as always... Everyone points the finger at European cars for having plastic coolant parts that randomly snap off when you breath on them. That same hose snapped off on my brother in-laws GM truck Christmas day about 1 mile from my house at like 10pm.. Guess who got a call to "take a look at it" 😒...luckily i was able to remove the nipple and temporarily rig it up for them.
YOU ARE AWESOME MARIO , FOR STILL PRODUCING THESE VERY INFORMATIVE VIDEOS AND NOT BING LIKE SO MANY OTHERS THAT HAVE FOLDED UP AND SEEM TO BE WITHERING AWAY . IT REALLY HURTS TO SEE WHAT IS GOING ON IN ARE INDUSTRY NOW THAT IF I CAN'T MAKE IT THEN I WILL MAKE DAMN SURE YOU WON'T ETHERE TYPE ATTITUDE . MARIO PLEASE KEEP UP THE GREAT WORK AND ALL THE BEST !
Great video Mario. You are right, these videos are not a substitute for a full-on training seminar but they are a slower introduction and the understanding of the principles behind this diagnostic technique does improve each time you release a video. Thanks for sharing man.
Mario I had to laugh when that coolant hose blew up on you man, there’s times that it feels like I’m the only one that happens too 😂 Like always great video, that Pulse sensor definitely comes in handy
I couldn't agree agree with you more Marion...if it's pinpointed to a specific cylinder sometimes a cranking/running in-cyl pressure transducer is the way to go and sometimes a leak-down test is best & sometimes both to get different failure related waveforms time permitting.
I can't say I'm at the level where i can use the in cyl to differentiate where the leak is coming from. I can really only see the expansion event showing that a leak is present, but not tell if it's an intake leak, unless it's really obvious and rounding of the IVC profile.
Great demonstration, Mario! That waveform speaks for itself: weak compression event --> immediate puff into the intake. Now, thinking about hanging the pulse sensor: would it be OK to raise the windshield wipers and clip the sensor to them or too much weight? And thanks for showing the underside of the diag process: made-out-of-chocolate coolant pipe bursting and the customer declining to do anything further. Tough industry...
Exactly why one shouldn't invest too much time and effort, and be as efficient as possible, the good thing is that we justified what we DID have to disassemble. It's not much weight, but I wasn't really considering the wiper arm as a support 😆 The customer declined moving forward at this moment, so we are at a standstill, no idea what they want to do with it yet. Thanks for watching buddy 👍
I just finish watching. Great diagnosis as usual with all you videos. Sadly you didn’t use the in cylinder transducer. I use it more now than the leak test. Practice makes you see more and understand the valve leaks and so on. Plus like you said it, I don’t like to try to spin a hot engine!! Lol
For sure man. The look on your face when the coolant started pouring was priceless. THe joys of working on older vehicles. You didnt miss a beat though.
Yo Mario every other video u do I'm slowly but surely understanding the waveform of the intake pulse testing. I gotta hit u up later and ask a couple of question. The stuff is really accurate and u are doing a really good job of showing how to set up and actually understand the logic behind all of it. Great job Mario 👏👏
Thank you so much for this video. I'm having this issue with my 05 HUMMER H-2. It looks like my Hummer will be sitting in the yard for a while until I can come up with the money to diagnose the problem.
HAHA well I had to laugh once I knew you weren't burnt. That has to be the worst design QD and they break all the time. Good thing for the customer was it broke there and not on the road. I get the GM PN and take them apart & double o'ring them and they fit nice & tight & seems to make them last and not leak or break . Dorman's are junk...used once and broke about a month later and the only reason I used them was it was at night and only parts store open had Dorman & the customer needed to get to his job. Nice diagnosis Mario & thanks for sharing . Hope you win the contest and deserve it. I've been voting 👍
Great video mario.. I have a 2003 h2 hummer multiple misfire.. I changed the plugs, wires, throttle body, coils, air flow censer intake gaskets and still have code p300. 😒
Hey mario. Gr8 vid and follow up of the pulse waveform to the leak down. Ive started a dont bring it if you dont want it fixed policy due to being messed around too much. Cheers dave
Great video Mario. I really need to start playing around with my scope to gain more diagnostic experience with it, I’ll be watching your videos more often. Btw what I usually do to perform a leak down test on gm v8s is loosen the rocker arm bolts, that way you don’t have to mess around with the crank pulley.
Mario as a new subscriber your videos is excellent. Trying to learn to decipher the waveforms as I'm new to using the scope and interpreting everything. Excellent video and channel and thanks for sharing 👍👍👍
Good job Mario. Always good at explaining yourself. Working on getting my pico hopefully in the next week. Gonna sell the Verus Pro and step up to the big leagues. Next,I gotta holler at Cody for one of his PPS.
Since you already had the VC off i would have backed off both rockers,no guessing if the valve is fully closed. I still prefer old school for mechanical. Good stuff though, i like your thought process.
Damn brother i feel your pain with that coolant hose and I'm a flag tech and I'm amazed at how you can film and work lol respect keep the content coming 👏👍
H2 was that not the worst vehicle several years back to back? Was a local shop this Saturday getting an alignment on the mini van ,they were a full service shop saw them lose 7 diagnose jobs ,a quick scan these days is so vegue , a scope diag is a better way to go but fewer are the ones out there that can proform that quickly and accurate Very impressive video I need to make time and use my scope more often
great vid .... I couldn't stop laughing when that coolant hose let go....I replayed that about 10 times... and the expression on your face is priceless ....thanks again for the vid marioo...... oh by the way, carlos from aes wave hooked me up with the pulse sensor and wps500 for a good price...i'v had them for about 1 week
I’m surprised there was no high intake manifold pressure code set from the map sensor, that Intake valve leak looked significant enough to have caused a code. Good diagnosis 👍🏻
Super Mario Diagnostics ps sucks about the coolant pipe, I feel ya tho fords are the same way you barely blow on it and they break haha good video hope to see more from you , cheers 🍻
Mr Mario in your opinion what suggested training can you recommend to get someone ready for ASE Certs particularly for electrical and engine performance p.s im already a scannerdanner premium member lol so besides that
There are apps that are geared towards ase prep. Type ase into your Google play or app store and study lol. Also take every prep question you can online. I personally used motor age prep books and kept studying until i could answer all the questions 100 percent correctly
I have not done any diagnosis yet besides hookup a $100 scan tool to the OBD 2 port. The 0P300 code came up, along with a bank O2 sensor code. This issue took place today while driving my HUMMER to military training. With 215,000 miles on the engine, should have known something major was going to happen soon.
The misfire occurs about a minute after cranking the engine. The engine will run rough for about 10 seconds then run normally. I've started this HUMMER about 5 times today. The misfire issue happen twice. Don't know if the sudden change in cold weather has to do anything with this issue.
I'd look into what code you're getting. An 02 circuit issue can cause misfires across a whole bank. But since the car heats up in open loop, it's not listening to the o2 sensors, not until it enters closed loop, then it will listen to o2 sensors and if one is problematic, it will cause those misfires. I had the same issue here, same system. ruclips.net/video/yCn0ZMAstEk/видео.html
Interesting, I do have a limited warranty with the dealership I bought the HUMMER from, but the dealership will probably find a way to avoid fixing diagnosing and fixing this issue.
Hey Mario great video. There is a better way then to remove the clutch fan. I've been a tech for 20 years and if your looking for conformation on a leaky intake or exhaust valve by way of air leak test, simply remove your rocker arms and the valves will be closed, mind you the piston will move after adding air but you will get the same results as if you were at TDC, it also works great for checking for head gasket failures. Keep up the great videos!! Oh that piston chart you had on your pico, is that something you downloaded? I would like to get one, they sell the charts on aeswave but having it set up on the computer looks way better.
got to work and smelled coolant. Popped the hood and noticed small drip coming from one of the heater hoses... lol...well you know what happened next lol I just replaced the plastic pipe that turned to puddy with OEM but I am counting the miles to take them off and just run the hose to the metal pipe with worm clamps.
Yeah, that coolant line break sucks. We (wrenchers) already know what's gonna come out of most customer's mouths: "It wasn't broke when I gave it to you." Hopefully, you're dealing with one of the more reasonable customers and will get compensated for "inadvertently" finding and fixing that coolant system ticking time bomb.
Hey mario...have a question... if u do a ckp /cmp relationship on a v8 ...with a cmp only on one bank, can the bank without a cmp still be out of timming....just trying to learn ..thanks in advance
Yes absolutely. Some cars have dual overhead cams with a cmp on only one cam, and the one without the cam sensor can definitely be out of time. Now if you're suspecting one back is out of time, you can do a relative compression test, and it may show lower amperage peaks every other peak. Also you can do a cranking intake pulse test using a map sensor, it will show breathing/timing issues as well. Many cars though, will have live data that compares specified/desired cam angle vs actual. If there's too much deviation from the two, timing/vvt could be an issue.
Those are some crazy tools man. I haven't touched a car other than oil and brakes since 1999. This shit is alien tech nowadays, probably came straight from area 51. Watching because my h2 has a misfire and I've already done plugs wires and coilpacks. Lol 😆 I'm just to bring it in.
Mario you ever come across this 5.4 on 2008 f150. could the timing phaser or actuator be off even though your pids for your phaser advance is reading right around 1 degree at idle? Bank 1 is dead at times (missing like crazy) but other times it's not to bad. Misfire codes that's it I've checked everything coils fuel control flow exhaust but can't find I reliable cam crank correlation for this vehicle. Any help from anyone would be good. Also bank 1 reads -18 rich fuel trims then bank 2 18 lean at idle (doesn't change underload).
@@SuperMarioDiagnostics yeah thought the same but checked it back pressure test. Have you ever heard of the timing being off but the pids be spot on. I've done a couple of these Ford's but every time I had a timing issue my pids would be 10 to 15 degrees off.
Nope usually the pids would show that it's off. Does your relative compression test show a lack of compression for one bank? I'd still loosen up both upstream sensors and recheck for misfires. The fuel trims opposing like that are usual red flags for exhaust restriction
@@SuperMarioDiagnostics it was a clogged exhaust. to be 100 % I took the shops word I was diagnosing for. They said they ran a back pressure test. they quoted the customer for a timing kit and was stuck on that but I was not convinced it was a timing issue. They wouldnt pull the trigger until I confirmed. So I removed 02s and it ran fine. I should of started from scratch and not jumped ahead on their word. Lesson learned. Truly thanks for they help. Some times I get side tracked and can't remember operation Theory. I work on everything I mean everything
That quick disconnect fitting. Brake every time. Just imagine customer decline the rest of the diag takes it out of the shop. That fitting brakes and who fault is it?
I know it doesn't cost much. I would tell the customer. Since that one broke the other is not too far behind. I recommend replacing the other with the hoses.
@@SuperMarioDiagnostics that is good.. stuff happens. I wish I could do this to a hemi at work, but no pressure transducer. I was thinking about trying to make one out of a fuel tank pressure sensor
Awesome work very thorough not sure why viewers accuse you for not being honest about your findings any good tech would take these steps with little variation. Good stuff thx for taking the time to share your knowledge.
The FML look on your face when the coolant leaked can truly be appreciated by a fellow wrencher 😭
