Timing belt change on 2006 Aveo LS: My new detailed write-up

[nostromo]

so after driving for roughly 10km the car died. I restarted I and drove it home, died halfway home, restarted it again and put it in the parking lot. I have no idea what is wrong.

think im just going to take it to a mechanic. if I drove it there could I damage the engine?

I used a battery impact with built in torque settings. Wish you could post a pic of your lines on the cams

I'm puzzled by what you wrote about tightening the bolts. You said 85 on the harmonic balancer (which should actually be 70 + torque-to-angles of 30 and 15). Did you pin the flywheel in order to get the 85? And, if you used a torque wrench on that bolt, why not also on the motor mount bolts? How about the timing belt components - did you use a torque wrench on those? Hopefully you did, because the timing belt is not a good place for guesswork.


Unless you can determine that it's something else, the possibility exists that something is wrong in the timing belt loop. Therefore, with the further possibility of it getting worse and trashing valves, I'd recommend you have it towed instead of starting it again.

Question guys, I have read through like 10 pages of info and have not come across it yet. I am looking at the contitech timing belt kits to do this job and they have quite a few. I am getting the one with a water pump included however I am stuck on whether I need the one with seals or not? Any advice on this? Thanks guys. This is the hardest job I have decided to do myself I have basic car skills.

When I did my replacement I bought the complete kit with water pump and timing belt. I didn't but the special wrench for the timing belt and regetted it a lot. I highly recommend getting it because it's a huge pain unless you have it.

Back to your question: does it say what seals it includes? The only thing I used was the gasket that came with the water pump- which any kit including a water pump should include.

The job is tough and takes a while, but be sure to take your time, double check everything, and when you get frustrated take a break before you eff something up. Besides the wrench I mentioned (Lisle 13500 I believe- 41mm), have a breaker bar/torque wrench and an Impact gun if possible- it will be a bit easier.

Also I personally found that having the timing marks slightly "dipped down" (both slightly lower than necessary) made it easier to have everything line up when putting tension on. Good luck- also if it matters I did it on a 2007.

Thanks for the advice! The seals the kit comes with would be camshaft and balance shaft seals... should I get this? I don't think I would even know what to do with it lol unless it's straightforward.

I ended up fabricating my own water pump tool... I had a 12 inch open end 36mm wrench and used calipers to measure it to the thousandths of an inch and used a side grinder and ground it to a 41mm.... 41mm is 1.614 inches lol

you mean one tooth up on the intake and one tooth down on the exhaust cam. plus the crank should be one tooth right of center looking at it straight on. then clockwise tension the water pump.

I also noticed the crank wanted to move when I tensioned the water pump. it was the only way I could "trick" it into lining up.

On a different 2006, I removed the head and replaced the valves my nephew bent when he tried to move the marks with the key.

I have two questions. 1) with a new gasket set do I need any gasket maker too or just replace each gasket?

2) the valves dinged the piston tops with slight crease marks. everything else is fine just want to know if they will cause any problems if I reassemble.

One tooth up intake, one tooth down exhaust

Guys I'm worried. I decided to take the cam pulleys off because I was having too much trouble getting the water pump off. When I removed the left one it moved a bit and unaligned. I turned it a few times to try to align it again and now I'm worried I messed it all up. The camshaft pulleys were rotated independent of each other and are not pointing directly up. How screwed am I? How do I fix this
