Ok so I know that there a lot of you Vibers out there that experts on the mechanics of the car. Is there a average milegae for a 2010 Vibe 1.8L for the timing belt/chain to be replaced?
Im at 85K right now and want to be prepared. Thanks in advance for the help.

Vibe uses a timing chain.
It's not a regular maintenance item, would ideally be good for the life of the car.

Thanks for the info....
