I have a 98.5 SE Sport.
I changed my water pump @ 60,000 miles.
I had the WHITE Water Pump and one of the vanes in the pump was CRACKED.
The housing cone in the pump body was still in place and I took extra care not to disturb it when I put a new impeller on my pump.

I bought the pump from AutoZone for $69.99, and now with over 76,000 miles,it has been trouble free.
