This is extremely helpful, although the couple hours estimate …. I’ve been there for two evenings. So 6 hours or so already , almost done though. It’s gotta be amazing to do it with the engine out.
Much appreciated. I got 2010 Cobalt that hasnt had to much wrong with it. Regular oil changes, plugs things like that. Only main issue was the water pump. I put that in, now the timing chaing tensioners i guess have went out. I can do this with the motor still in the car! Awesome video!
My service manual shows both "fixed" balance chain guides at 133 in-lbs or 15nm or 11 ft-lbs. You seem very knowledgeable and can you double check and see if it has changed or if my manual is incorrect?
Good catch! I looked up two different service manuals and procedures and one says 89 inch pounds and the other says 133 inch pounds. I don't see a reason why you couldn't follow your manual with those torque specs. I believe both guides use the same bolt thickness so they can handle the same amount of torque stress. I hope that helps 👍
@@kyniarichardson2823 I just finished up this job in my cousins drive way. It’s honestly not that hard of a job. Hardest part is the timing. I ended up spending $250 for the entire timing chain kit, maybe $40 for all the gaskets and replacement bolts. Took me roughly 3-4 days but I only worked about 3-4 hours at a time. I didn’t pull the engine though.
Is this basically the same when it comes to doing the chain on an LSJ engine? Mainly the procedures for the chain. I know the valve cover will be different.
So I followed everything! Thank you for the awesome video! Very helpful! I am nervous because I learned what an interference vs non interference engine is. Is there a way to know if your camshafts were in the correct position? Mine would almost click into place and I’m not sure if I got the correct position. As long as I got the exhaust and intake sprockets in the right place should the camshafts have followed to the right place?
These have two chains. A timing chain and a smaller balance shaft chain. When removing the water pump the sprocket can stay on as long as you remove the balance shaft chain connected to it 👍
Thanks, we replacing both chains and all sprockets. Everything I found shows using a special tool to remove the water pump, just wondering. Changed out pump today without removing the exhaust manifold, timing sets go on tomorrow. your video was most useful.
Also had another quick question. What if the new chain does not have timing marks on them. As long as the cams and crank are lined up right, can you just put the chain on? Maybe mark them with a paint marker after doing so?
The new chain needs timing marks. There are a specific number of chain links between each sprocket. Being off just one link can cause issues. If your old chain still has colored links you can transfer the locations with a paint pin or fingernail polish. If the old chain no longer has colored links then mark the links before you remove the chain.
Only if you are replacing the balance shaft chain. The sprockets have timing marks that get aligned with the new chain. But if you're just replacing the main chain then you don't have to worry about the balance shaft alignment.
He is saying a couple of hours. However, he had to take the whole engine out. Meaning that he had to remove the transmission, exhaust, cooling, electrical, vacuum lines, etc. I am looking to do this job myself and most say this can be done with the engine still in.
Yes, the engine does NOT need to be removed. I already had it out to rebuild it and took advantage of that to show how to reset the timing. But everything can be done with the engine still in the vehicle 👍
@@ValleyMobileAutomotive Im not picking on you , but that tensioner was already activated . 12:05 the plunger on that tensioner is out at least an inch .
@@js4187 I see what you're saying. It's been a while but I know a new one got put in. It's possible I put the old one in then realized it and put the new one in but the wrong portion of the video was cut out 🤔. Either way good catch 👍. There is a way to press in a used tensioner in order to reuse it but I've never tried.
@@ValleyMobileAutomotive I only commented because I just went through this exact thing . New timing chain set and the tensioner was already activated out of the box . They can be reset but you have to remove the snap ring, take it apart etc . But your work is spot on . Very cool channel .
@@K1NGPUFF I took mine apart cause my tensioner came loose and it skipped time and I wanted to redo the whole chain but I got told I’m better off getting a new car cause I possibly bent rods
@@tuxyvlogs8533 oh u had me scared because i plan on doing the waterpump myself since no shops will do it and the ones that will want $1200+ and do the whole timing chain
@@tuxyvlogs8533 have u ever done the waterpump yet? My shit leaking bad thats why im replacing it, just one of my spare cars gonna be my main doordash car tho
