Does anyone have any recommendations on when to change the timing belt in the H3? I haven't looked at my owners' manual, I used to go to the dealership for service but I stopped going there a few years ago. I have 74k miles on my 07

 

All H3's, H3t's all models and all engines have a timing chain and not a belt. I assume that it is only to be replaced if it breaks or stretches causing timing issues.
