In that case, take the timing cover off and inspect it. Usually if the belt was replaced, there will be a sticker somewhere saying the date/mileage. Most timing belts come with a sticker as a reminder...Comment

visual inspection may help, i mean im sure you know what a new(er) belt looks like. but you seem like a strapping young man, you don't wanna turn a timing belt job into a head swap do you? :D1991 325iC - Mauritsblau sumthin metallic blue. DEAD

Removing the timing cover is half the job in itself. If you are unsure, just check.
After you replace it, though, you can check the condition. Just look on the underside for cracks. Deep, perpendicular cracks are bad. Small little slits are generally okay. However, a timing belt is pretty sturdy compared to a v-belt.Me: "I can't wait to redline my car!"

Seriously everyone? Its very easy to check.
Heres what you need to do.
Lift the black plastic cover, and feel it. It should have a little bit of slack, I believe no more than a 1/8in? Make sure you put the cover back into place. You really dont have to take it off, you can noodle your fingers underneath it.

Yeah, but if the tensioner was tightened properly, and isn't at the end of the slot, then there shouldn't be any slack. My concern would be the age of the belt, as I have seen a few belts go on customers' cars, one appeared to be in excellent condition, yet about 6 or 7 cogs ripped off it.Comment

timing belts aren't easily inspected. It may seem to have proper tension and look good while tensioned but once you take it off a whole different story.
P.O. of my vehicle told me that the t-belt was replaced 20k miles ago. Considering a t-belt and water pump job costs about $70 in parts I was like minuswhale do it for peace of mind. Took the covers off belt looked okay good tension. take the belt off and flexed it and could see cracks in the belt and peeled off a good 5 inch piece of the belt of the smooth side of it.Comment
