My water pump was leaking pretty bad so I changed my belt, pump, tensioner and a few other things at 90k. To my eye, the belt looked fine. No cracking visible but I don't think you can see stretching in the belt with your eyes.

Personally Jo, I think you will be fine given the amount of miles you haven't put on your VX. However, if you are leaking coolant from around the water pump (will be visible on the timing covers) then I would go ahead and change it.

Otherwise, you will likely be fine for a while longer I would think.
