If my recent perusing of the many, *many* water pump complaints is any indication, for f*ck's sake, don't drive it til except to get it to the shop! All the many posts scared me so bad I went to Autozone this afternoon and ordered a new metal-impeller pump for $70, and though there's (currently) nothing wrong with mine, I'm gonna try and replace it next weekend or the one after. These engines apparently don't take overheating very well...good luck not killing yours. Let us know.
