Original water pump failed @ 32,000 mi. 1st replacement pump failed @ 68,000 mi. 2nd replacement pump failed @ 95,000 mi.
So, I'm on pump #4 @ 98,600 mi. 3 FAILURES in 95,000 mi. I'm 2nd owner, bought car just prior to failure @ 68,000. Thought it must be a fluke. Now I know better.
R & R pump every 30,000 mi.
2000 986 base.

I replaced mine with a Beck Arnley 131-2307 Water Pump which came with a metal impeller as opposed to the oem's plastic, I am hoping that if nothing else, the fins won't break off and cause more damage.

Metal impellers are a no no. They can damage the block when they break. Why do you think Porsche uses the plastic. My 2000S with TIP, 78,000 miles with the original water pump and original coolant. Now, if you live in a cold climate and it freezes a lot this may cause the plastic to weaken, I live in Florida. Just my opinion.

Calendar time is the killer for impellers, not mileage.

When the bearings start to wear, and shaft begins to wobble (as all water pump shafts do over time), those metal impeller blades can make contact with the engine case and do some damage.

Mine just failed catastrophically. When I left the garage no noise, no drips on the floor, no smell. The pump had been replaced 1.5 years ago and the coolant level had not moved more than an ounce or two since then. The old pump was flawless and spun smooth and all that. All of a sudden near Sonoma the 308 that was behind me started to hang back a ways. A mile or so later along with clouds of steam the low coolant light came on and 5 gallons of coolant was on the road in minutes. I have yet to pull it apart again, but I can see where the pulley has hit the pump and any water that goes into the car comes strait back out.
