Water pump rattle ?

Thanks Steve,
My initial post may have not been thoroughly clear. Your suggestion is the procedure I used.
Now the inevitable "While I Am In There" question.
I plan on, of course, the water pump and gasket.. Also thinking hoses, clamps, tensioner pulley, air horn gasket and belt.
Anything else I should do? Don't have any oil leaks (already fixed them) so am good there.
Appreciate the feedback.

Kenny,


Sounds like your on the right track.


Good Luck.

Thanks Guys for the responses.
I am going to peruse it once more this weekend and, if no new findings, will order the parts from Jerry next week.

Bringing this thread to a conclusion.
Ordered parts (water pump, hoses, clamps, gaskets,) from our favorite parts supplier, Jerry's. Upon removal of the water pump it was obvious it was the culprit causing the rattling sound. The shaft had a bit of play and the noise was being created by the impeller making intermittent contact with the housing. The pump was NOT leaking and showed no signs of previous coolant leakage.
Thanks for everyone's input.
