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 👍
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 👍
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?
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.
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.
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.
@@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

Now that’s a good “how to video” 👍
Thank you for the tips!
Se me olvida felicitarte por el gran trabajo y muy Limpio que haces amigo 🎉
This was an excellent video. So helpful
Thank you for time lapsing the part I came here for. Amazing work
Oh no! Were you able to get help with it? What part did you need help with?
the back chain kit an front part numbers for them
That oil looks pretty healthy.. 🙃
Thats why he took the motor out and did major work to it off-camera of course
Great sarcasm tho😂❤
I have a Chevy Cobalt and the same thing happened to me and I took it to the mechanic and they ended up taking 4 days to get it fixed😂

be sure too check your oil pickup tube depending on how bad your chain guide was eating up
@valleymobileautomotive where are you located? My local shop doesn’t want to do this for me. 2007 cobalt
Are you able to replace the water pump while it's still in the car, thought it would be a good idea for me since I am doing to be there already
@@kevinmartin1679 Yes you can. I don't have a video on it but if you are doing the timing chain then the pump isn't much more work 👍

Your chain will have colored links on it. As long as the colored links matched up with the timing marks on the gears you should be all set 👍
@@ValleyMobileAutomotive awesome thank you!
That water pump bolt is 12mm not 15mm also 1 1/4" socket fits on the chain tensioner.
Also that big open area in front of the engine he's working in is made by removing the windshield washer reservoir.
Does this apply to the turbo and supercharged 2.0?
thats what I was wondering good luck bro
The plug you need to put atv around. What did you use to take it out?
Looks like they need a head gasket too.
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.
The procedure should be very similar. Some of the torque specs may be different though.

@@ValleyMobileAutomotive I'll be getting a new chain with the colored links. Thanks!
Hey i was wondering do the balance shaft have any marks that i have to align
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.
Tengo mi Cobalt que necesita ese trabajo cuanto me sale con mano de obra y respuestos ????😢😢
How did you torque the damper pulley bolt or did you just use an impact set to 120?
Чудова Робота 👍 👍👍💪💪💪
What are the torque specs for t he sprockets?
12:13
Thank you
But I was wondering about the balance sprockets? Or whatever the lower intake and exhaust ones are called
@@daltonwhite9810 The balance shaft sprocket bolts are 37 foot pounds 👍
If i only change the cam chain do i have to mess with the water pump chain?
No, the water pump chain is behind the main timing chain so it can stay in place 👍
when changing the timing set with water pump does the sprocket need to be removed from the pump to remove and or put back in.
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 👍

@@user-fy9dq8ez6v Nice! Glad you got it out. Yeah, the special tool is so you can do the pump without removing the chain.
Real time, how long did this take?
Four to six hours depending on your skill level.
My daughter has a 2010 Chevy cobalt. Does that one have an inference engine
every car has an interference engine these days. i dont think they made a non interference engine since the 90s
Are you able to do it without taking it out of the car?
Absolutely! I already had it out to rebuild it, so showing the timing alignment was easier to film. But you do not need to pull the engine 🙂
Tensioner does not go in already activated . You showed yours activated .
Maybe the camera angle made it appear activated? It was a brand new tensioner out of the box 🤷🏻♂️

If you did the tensioner then why are you doing the timing on the same vehicle
This engine has been pulled apart more than once. I was able to record a few different repairs on it 👍
what's the part numbers for this
This was a Cloyes timing kit from the local parts store.
