It only squeaks when its warm so last night I took the belt off, again, but this time while the engine was warm (ouch) and its the water pump that squeaks. I didn't think it was the pump because I changed it 13 months and 24,000 miles ago (its still clean.) The pulley has a just barely noticeable amount of play, and the weep hole has just a touch of dried coolant.

What does this all mean?

I bought the pump from fastlane, is there a warranty?

Can I lubricate it, and with what. I'm worried about oil cause it might dissolve the seal, but what about synthetic oil? I was also thinking about graphite, silicone, and Teflon as alternatives to oil that may be nicer to the seal.

Does this mean imminent threat of pump failure?

Lots of questions.
