HI,
I am getting set to do a timing chain replacement on my 2006 hhr 2.4.
403,000km or just a bit over 250,000miles. Can this be done with the engine in the car or do I have to pull the motor. I do have a 2 post lift in the garage so either is possible but I prefer not to pull the motor unless I have to do more such as crank bearings.(hoping not to go that deep as its not burning a drop of oil yet between changes.

Has anyone ever heard of having to change the balance shaft chain, or do you think its safe to leave as is.
Thanks
Dale

 

This is from a Cobalt site and maybe some help to you. http://www.yourcobalt.com/forums/ins...ing-chain.html

 

You don't have to drop the engine but you need to lower it. Which it does make the job harder if you leave it in just because the lack of room. Change all changes and guides and etc . Do it right the first time!


Takes care

 

I hope things are going smoothly as you are doing this to your HHR. This seems like a pretty touchy project. I wish you the best as you do the change. I look forward to any updates or pictures you would like to share.

Still have not done it. But I just picked up a replacement motor to swap in soon as I get a chance. Picked up a 2.4 le5 from another 2006 with 65,000 km or 40k miles for $400. Should get me and the car well up past 500,000 km or 600,000.

Holy smackers, thats getting up there. Ive heard the tensioner and guides usually go before the chain.
