Does my 2007 HHR have a timing belt or chain?
I've got over 120,000 miles on my car, and have had no problems whatsoever.
I hear that if it has a belt, it should be replaced at 100,000 miles, and I don't want the belt to break and ruin the engine

 

Hhr has a chain

 

The chain has a tensioner though. If it hasn't been changed yet you might want to, it's not expensive.

 

Thanks so much

 

you have chain.. should get a timing chain set from ebay youll save money then get a serpentine belt tensioner and belt.. do it all at once.. piece of mind..
