90K is recomended for the T-belt for your 99 and the 96. It's part of the 90k mile service. The older models (94 and down) are recomended at 60K. The belts are made stronger for the newer models. I've heard of belts lasting almost 200K, but anyone who knowingly pushes their belt that long (in a 95 and up) doesn't have too much brains. 95 and up have interference engines.
I wouldn't chance it too far on an interference engine. It wont last forever. It's a procautionary issue to do it soon, before it breaks and then ya need a new engine. Age an issue? What else has failed or gone wrong with your 12 yr old car?
Is age an issue? Its the original belt, which makes it 12 years old. I guess I better change it soon.
yes age makes a difference, like every other rubber on your car, they start to deteriorate after the years go by. i would recommend doing the timing belt sooner then later. always good to do it right when you buy the car to just get the thought of it snapping/skipping out of your head from the get go.
