09 Timing Question...

Ive read online that Ecotecs have history of failing Timing chains, tensioners and what not. This is my first gm, its an 09, 73k miles, auto 2.2. Now is that Timing chain kit a necessitity to keep my car running or with it being an 09, has it been taken care of by gm already? As i see a lot of the years online seem to be pre 06's and whatnot. I like my Sedan and want to keep maintenance up on it. Thanks for any help guys.

Pull your valve cover and make sure there is no slack on the chain

I wish I could get my chain and tensioners done under warranty before it ends.

Ok so slack would be a sign of worn tensioners? Or worn out chain? Or both? Lol

Worn tensioners and or stretched chain. But you have to know how much slack is within spec. A little slack will be normal.

My maintenance schedule says to inspect or replace the chain tensioner every 160,000km, but nothing about the chain. When I worked at Honda, we had to replace the chain and tensioner (among other things) on an '06 Civic with 200,000km, mainly because the guy had barely any oil, and what he did have was gunk. So keep it topped up and change regularly, also, spend the extra 10 bucks and change the filter too. I hope that added some bit to this thread.

With these cars slight overfill is less dangerous than underfill. I always make sure mine is never below fill mark, even if I only have to add 100ml. Regular oil changes will make that chain last a lot longer.

The tensionner has 3 stages of tightening once it reaches the last stage and chain has too much play, you should change the chain.

The tensionner in it's preset protrudes .3 inches, first stage will release it so the play is between .3" and .45", second stage is from .46" to .6" and last stage is from .61" to .84".
So as you can see the tensionner is designed to take up to .5" of play out of the chain as it stretches or rather as links wear.
