Is there a guide to replacing the timing belt?

Title says it all.

I have a 2008 aveo approaching 100k and I'm looking to replace the timing belt. Is there a guide to help me along the way? I am a heavy equipment technician apprentice so I know my way around a machine, but cars are a touch different and I have yet to change a timing belt.

Any assistance would be wonderful.

Also, what price is a decent one for a timing belt, and what other components should be replaced?

edit: Also, i'm getting a rough idle condition on start up and I plan to check some of the possible reasons for this on the weekend. It's possible that it could be a valve setting issue, no? This is one of the last things i will check and I'm curious what the proper valve lash setting for the 1.6l is.

Thank you!

There is no lash to adjust as the valves have auto adjusters. I'd search the forum for a how-to on changing the timing belt. In the how-to, you'll be shown how to properly set the timing. Just look in the How-To section.

You can click on the link at the bottom of my post. It's not the best write up, but its what I did, with pictures and description, to change the belt. There's a link there to order a belt kit through amazon if your interested.

Good luck. I'd have the plugs and wires changed too, and see if the rough idle goes away. Also... you may want to hold the cam sprockets together with tie wraps. Not a bad idea at all.

Thank you for the replies.

I have found a walkthrough that seems to do a good job of explaining the job.

The spark plugs were replaced recently...10k or so ago...but the wires were not. I will look into getting new ones. It should be said that the car is only rough when first started and sometimes when stopped, such as at a red light. When acting rough when stopped, it seems like it wants to lurch forward.

Rough Start Idle

I was having the same issue with my 2008 a while back. Only mine got the the point where I wasn't even able to accellerate. Replacing the wires did the trick.

Usually when a timing belt is replaced you should also replace the water pump and the timing belt tensioner. Since the job is substantial and these items are in the same inconvenient area it's best to replace them all at the same time

You can go to www.youtube.com for ideas. They have several videos on replacing timing belts although I could not find one that was Aveo specific.

As far as this timing belt change thing. I hear that 50k is when, 60k is best and then I'm reading threads with people who have 100k plus and changing. My aveo5 just turned 50k and runs like a timex. Motor sounds great. I have no reason to believe at this point that it wont get up to 100k with any trouble. So should I change the belt beacuse people say to? Is there any warning signs at all that it needs to be changed or does it just simply give out and engine damage occurs?

I responded to another post you made in another thread, but intervals are 100k miles on the 09+ so you are fine, no reason to change it anytime soon.

I ran the stock timing belt on our aveo 100k miles and then I changed it. Maybe that wasn't a good idea, but I didn't know it needed changed so soon. Just saying...

Also, this thread is old.

100,000 miles is the recommended replacement period, unless there is an issue with the belt. If your technician advises for a replacement, there may be belt wear. I encourage you to consult with your technician for additional information.

The recommended timing belt replacement information is also listed in the owner's manual on page 6-7 of the Scheduled Maintenance section.

For your convenience, a digital copy of the manual is available at: http://www.extendedgmwarranty.com/ow...rolet-Aveo.pdf

If you have any additional questions or concerns, please feel free to contact me.

Louis, does gm replace the timing belt for free (under 100k power train) if it is worn before the 100k maintenance interval?

petrified.rabbit,
Here is a little bit more information on what is covered and excluded from the Powertrain Warranty. For more detailed information, I would recommend speaking with the Service Advisor at your dealership. I hope this information is helpful. Please feel free to PM with any additional questions, comment or concerns.

Engine Coverage Includes: All internally lubricated parts, the entire pressurized fuel system (in-tank fuel pump, pressure lines, fuel rail(s), regulator, injectors and return line). Also included are all actuators and electrical components internal to the engine (i.e.: Active Fuel Management Valve Lifter Oil Manifold, etc.) as well as the Engine/Powertrain Control Module, module programming, cylinder head, block, timing gears, timing chain, timing cover, oil pump/oil pump housing, OHC carriers, valve covers, oil pan, seals, gaskets, manifolds, flywheel, water pump, harmonic balancer, engine mount, starter motor, turbocharger and supercharger. Timing belts are covered until the first scheduled maintenance interval.

Exclusions: Excluded from the powertrain coverage are sensors, wiring, connectors, engine radiator, coolant hoses, fans, coolant and heater core. Coverage on the engine cooling system begins at the inlet to the water pump and ends with the thermostat housing and/or outlet that attaches to the return hose. Also excluded are engine oil cooling hoses and radiators.

I asked our dealer for a copy of the GM Document 2076951 which shows the procedure for camshaft lash adjustment for the 2009 model year, I am not sure how many years forward it covers though. They provided it to me no questions asked. It's a copyrighted document so I can't post it here, but you at least know where you can find it.
