Timing Belt or Chain

Hi,
could someone tell me please if the 2008 Chevrolet Cobalt LS has a timing belt or chain?
Thanks.

Steel chain? Great. That means no need to change it? Worry free?
Thanks.

Not worry free. Tensioners tend to fail, leading to failed guides. If those combine to form a really loose chain, you can jump time and damage valves, pistons etc. Not sure if all models have an updated tensioner you can buy, but if you do, ensure you do not lose tension on the chain at install and jump time.

VVT engines need religious oil changes to keep the variable timing working smoothly.

John do a search here for

He will show where it is and how to tell if you have the updated or early version that is prone to breaking.
