Water Pump Replacement on High Mileage Car?

[Hasdrubal]

I'd just drive it home, but I have AAA and they'll tow something like 100 miles a few times a year before they start charging by the mile over whatever the limit is. I agree with dghii, the chances it fails right then are pretty small.

I have no idea if my car has the original pump at 91k, and while it's on my list of things to do, I'm not afraid to drive the car until then.
