Redbug - have you opened your truck yet to see what damage has been done, if any??
FWIW - my waterpump went on my '97 Rodeo, causing the belt to jump a tooth, sounded godoffal terrible, but no damage was done.
I put on all brandnew parts, I would not choose to do a reman waterpump.
My list consisted of: waterpump, timing belt tensioner, belt, idler pulleys, crankshaft & camshaft seals.
