There are many horror stories concerning rebuilt water pumps,if you want to do it once use the GM pump or the Fiero store
water pump.. the Fiero store pump is New,buy the thick gasket, this area is hard to clean ,avoid the use of a steel putty knife to remove the gaket, I warn you!!
do not get a cheap water pump from rock auto Or one of the major chain parts stores they have a very hi failure rate .a member of our local club had to replace the pump 3 times,, get a new one
buy quality & replace the timing chain also,, the timing chain is a neglected part on most high mile cars unless you have run Synthetic oil from the first oil change yes the water pump can be installed thru the wheel well
make sure you mark the balancer so you know if it separates
would like to hear from you if you installed a Fiero store pump properly...
