Bob,
My fan is nice and tight too. I'm ordering a new pump today as after I took
the pulley off the coolant does appear to be coming from the relief hole in
the bottom. If you find someone that re-builds one let me know too as it
seems a waste to throw the one I have out as it's pretty new.
Oh, btw: took the TD to the airport this AM and it's leaking again.
Best and thanks,
Scott
