Timing Belt.......When?

[JAMAS]

What should dictate when I change my timing belt?

Time or Mileage?

Then my followup question, what is the recommended time/mileage?

I have a '99 with about 52,000 miles.

Thanks!

100k miles is the recommended service interval in the owners manual.

Though being ten years old, it couldn't hurt to change it earlier, I'm @ about 70k, & it's on my list of things to do when the weather gets warmer.

Thanks dude.

IMHO, do it at 100K miles (along w/the water pump), unless your water pump craps out on you sooner - then be prepared to do both at whatever time the WP goes South...

Good call on the water pump, also, a new timing belt tensioner is considered cheap insurance..

100k miles = ~10 years for normal use, so use the decade mark as a rule of thumb if you are well below normal mileage (that's the outcome of the debate on the 928 forums - age is as important than mileage, if not more so, for parts).

That said, there are two schools of thought on the water pump... some say replace it while you are there. Others say it's foolish to replace a proven-to-be-perfectly-good part with an one with unknown reliability. More than one person has replaced a water pump when they did their t-belt and had it go bad in the first couple of weeks.

Replacing the tensioner is a very good idea, though, IMHO - it's seen some wear and tear after this much time.

x2, I'm at 86k and I want to do mine before I hit 100k as well. I'm gonna do the whole sha-bang-bang this spring. Timing belt, water pump, idler pulley, and a few other things. I hope my coolant leak goes away as well.
