HOW TO INSTALL Harmonic Balancer - GM 4.2L Envoy/Trailblazer

[@FranciscoJavierOutdoors]

Brother thanks for the bolt on the flywheel trick!!! I ended up using a short 16mm impact socket and didnt even need to use a jack to hold it in place. It was short enough that it just stayed in place vs a longer deep sock that can wiggle. I was able to torque the balancsr bolt, those 180 degrees was wild! Hahaha, thanks again bro 🤙

[@KevinNadeau]

👍 glad it helped

[@franklinorsini902]

Good job Kevin !!, Now I have a clearer idea of ​​what I should do. Greetings from Venezuela

[@KevinNadeau]

Excellent. Im glad the video helped you. Good luck with your truck!

[@voidisyinyangvoidisyinyang885]

the engine sounds great.

[@stevemurphy-sr2bb]

Is there a video of you removing the harmonic balancer bolt?

[@KevinNadeau]

I just used my pneumatic impact to remove the bolt, nothing fancy there.

[@ericcorse]

Holy cow 110ft lbs + 180 degrees mighty snug.

[@korbynpaxton410]

a trick: watch movies at Flixzone. I've been using it for watching loads of movies these days.

[@lionellavallee1919]

Hello me again If im seeing correctly. You had a 16 mm socket on the back of the crankshaft and a block of wood pressed against the socke??

[@KevinNadeau]

@@lionellavallee1919 yes that’s correct

[@lionellavallee1919]

​@@KevinNadeauthank you. Almost to that point on my 2004 trailblazer

[@ericpfiffner5615]

You forgot to put Miller or 'insert your favorite beverage here' in the parts list. Definitely required for this project! Great video set, thanks.

[@KevinNadeau]

Eric Pfiffner Great point! Thanks!

[@DuckMallard11]

When I'm installing the harmonic balancer how do I know it's all the way on? Will it just not go any further or what? I suppose I should have measured the gap between the balancer and the timing cover before I pulled it off but I didn't do that.

[@KevinNadeau]

If I remember right, it should bottom out. You should be able to tell by the serpentine belt alignment.

[@johnjesus971]

Good job on the videos! It's going to help a LOT. Wish I had access to a garage though. It's starting to get cold here in Michigan. Might just let the Voy sit all winter and do it in the spring.

[@KevinNadeau]

Thanks! Good luck with your truck.

[@dmoyanaise]

Kevin, have you noticed any leaks from the front crank seal? The reason I ask is the GM Service Manual says to install the Friction Washer between the front cover and the crank sprocket.

[@KevinNadeau]

I have not noticed any leaks...knock on wood.

[@dmoyanaise]

@@KevinNadeau I hear that. Just wanted to ask since I'm finishing up the same job and read last nite the thing about the friction washer. Only says that in the Svc Man. Nothing in Chiltons or Haynes or in any of the numerous videos I've watched.

[@andreszamora2251]

Do you have to apply lock tite to the harmonic balancer bolt?

[@KevinNadeau]

I don't remember using Loctite on mine

[@johnkendalljr6165]

Do you have to put the harmonic balancer on a certain way considering there is no key way to line it up?

[@KevinNadeau]

I don’t remember putting in on any particular way👍

[@ericcarter2297]

how do I hold the flywheel with the torque converter still installed?

[@KevinNadeau]

There's a special tool for it, but I used a socket at the back of the oil pan. Watch around 8:35 to see where the socket goes. Not the best way, but it worked.

[@chrisgolib7710]

@@KevinNadeau Great Videos, so helpful. Im confused about the socket. Does the socket go on a nut in the flywheel? or does the socket just keep the flywheel from moving? I will have the pan off, again to replace the oil pump and harmonic balancer but dont know how to keep it from turning. i wont have the top of the timing chain removed. dont have access to a impact wrench.

[@KevinNadeau]

@@chrisgolib7710 The socket goes over one of the bolts. Good luck with your truck.

[@RonD1217]

I have one thats a 2006 trail blazer with the same engine rear wheel drive though. And it has the ticking noise. What did you do to fix it? And what is it?

[@KevinNadeau]

My problem was low oil pressure and the culprit was a clogged pickup tube.

[@michaelvanvleet998]

I have the same problem with my 2006 trailblazer. I am seriously considering cutting an access hole in the oil pan. I could tap and drill four small holes and bolt a small cover plate over it.

[@KevinNadeau]

Michael Van Vleet Someone else suggested pouring about 2-3 quarts of parts cleaner into the oil pan to try and dissolve any gunk on the pickup tube screen. Let us know how you make out with it.

[@michaelvanvleet998]

If I tried that, would the oil pan drain completely through the drain plug? Also, how close do you think the pick up tube is to the bottom of the drain pan?

[@KevinNadeau]

Check out my other video to give you an idea of how low the pickup tube is in the pan. Starting around 5:20 kzbin.info/www/bejne/l3nQlH2gn9GZb9k

[@KevinNadeau]

Not all of the oil would drain out if the car was on a flat surface. You would need to raise the rear of the car to get most of it out of the pan.

[@michaelvanvleet998]

I plan to try that in the next week or so. Just concerned about getting too much cleaner in the oil pan. I do not want it to get up to my main bearings and I must be able to drain it all out, You might want to consider posting your videos to trailvoy.com. It is a great resource to trailblazer and envoy owners, yet there are no video solutions to what we are experiencing. I will let you know how it goes when I give it a try. Thanks for the videos!

[@randallrigdon9379]

Thanks for writing back. I went on graingers website and they dont list the thread of bolt. Last question do you wanna sell one of those tools. Or can you tell me the part number for the kent moore tool. Thanks again

[@KevinNadeau]

The Grainger Item # is 10P801. I just checked their website and it's listed as $9.35 for a 1 meter piece. I still have a couple of the installers that I made and would be happy to sell one to you. Send me an email to [e-mail] if you're interested.

[@jerryc3201]

Are you suppose to line up the oil pump a certain way when you put the timing cover back on?

[@KevinNadeau]

No you do not. The teeth on the oil pump gear will line up with the teeth on the crankshaft.

[@jerryc3201]

@@KevinNadeau that's what I thought but I have knocking and no oil pressure after timing chain replacement

[@KevinNadeau]

That's a sinking feeling. I hope your pickup tube isn't clogged like mine was.

[@jerryc3201]

@@KevinNadeau I made sure the screen and tube were free of any kind of debris

[@KevinNadeau]

Have you changed the oil pressure switch? They are known to go bad.

[@randallrigdon9379]

What's the size of the crankshaft bolt

[@KevinNadeau]

The harmonic balancer bolt is an M16-2.0 thread.

[@RegularCarGuy]

Will this work for EXT model

[@KevinNadeau]

It should if you have the same motor👍

[@HandyTim]

Also how are you holding your crank still?

[@KevinNadeau]

I used an impact socket to hold a flywheel both. It wasn't the best or safest way to do it though. I recommend getting a flywheel holding tool and doing it the right way👍

[@fsu3784]

How did you stop the crankshaft from spinning when tightening the bolt?

[@KevinNadeau]

I talk about that around 8:15 in the video. You're supposed to use a flywheel holding tool that goes in the starter motor spot.

[@fsu3784]

Just read bro my bad. Thanks for the video!!

[@FranciscoJavierOutdoors]

​@@KevinNadeau cool man about to have to do this, so you just used a socket, no wrench attached? Pushed up on the socket with the wood and jack? Thanks

[@KevinNadeau]

@@FranciscoJavierOutdoors that’s the way I did it. But of course the correct way is with a flywheel holding tool that you have to first remove the starter in order to install.

[@FranciscoJavierOutdoors]

@@KevinNadeau thanks man, yeah I can't find the tool for this specific engine, only for the LS. Preciate the info 🤙

[@rabmanrabman]

what tool did you use for the oil pressure gauge?

[@KevinNadeau]

The gauge I used initially was a 0-400 psi Matco (www.matcotools.com/catalog/product/ATG4AK/transmission-and-engine-oil-pressure-tester/), but then I switched to a 0-100 psi gauge. I don't remember where I got the second one at, but I'm sure you could find one on Amazon.

[@rabmanrabman]

@@KevinNadeau you didnt need a special tool to adapt it to the engine? where did it hook up? did you plug it into the oil pressure switch port or the allen plug in front of the filter housing? from what ive seen there is a special tool that goes in place of the oil filter that is apparently suppose to be used but some ppl buy an adapter for that allen plug spot to fit the gauge adapter

[@rabmanrabman]

@@KevinNadeau and thanks for the reply and the videos i really appreciate it!

[@cbarnesngss86]

How did you hold crank in place while torc ?

[@KevinNadeau]

With a socket through the back of the oil pan to hold a flywheel bolt. A little sketchy! I recommend doing it the right way with a flywheel holding tool.

[@xx-ps5qv]

how do you keep the crank from turning when removing and installing the bolt?

[@KevinNadeau]

I used an impact wrench to remove the bolt. To install, i used a socket in the back of the oil pan to hold one of the flywheel bolts.

[@xx-ps5qv]

well its my dads vehicle. i am not sure he has to dig that far into it to get the leak. probably have to buy a chain or strap wrench like the book shows, but good to know if we have to take it that far. thank you for replying. most people would just leave everyone in the dark wondering how its done.

I'm having an issue with my harmonic balancer throwing the belt over a notch and ripping a line off the belt. What do you think causes this?

[@KevinNadeau]

Is the belt the correct length? Is the tensioner working properly?

[@HandyTim]

Yeah it is I think the balancer may have been reinstalled without the washer

[@HandyTim]

Either that or they didn't put a new bolt in

[@KevinNadeau]

@@HandyTim Oh no. Also, those bolts are torque-to-yeild (aka one-time use). Be sure to put a new one in.

[@HandyTim]

Yes I think the harmonic balancer was pulled to replace the water pump but the timing chain cover looks new so I'm thinking the harmonic balancer was off before and wasn't reinstalled with the proper friction washer as the balancer seems to sit further back or the harmonic balancer they installed may be defective. I bought the new power version

[@agustinmares7114]

Kevin nadeau Could you share the link of the harmonic balancer install tool please I've been looking for it and I don't know what it is, a lot of different measures come out in the description it says that it is compatible with ls lsx ls1 ls2 ls3 ls4 ls5 and lq9 en gine i home you can help me.
