How often do you guys replace your belts if they don't shred? I had some tensioner issues awhile back that was fixed with the steel tensioner and since then I have had the same belt on the car. It is a gator back and my question is since it has been like 1 1/2 almost 2 years on the car should I replace the belt? The last time I had the belt off it went on real easy and I am thinking it might have stretched alittle. Do belts stretch without breaking?
