G'mornin, guys,

I changed my water pump yesterday ('88GT manual). It took about 3 hours, but then I am an old fat disabled slow mechanic (giving myself the benefit of the doubt!).

This link https://www.fiero.nl/forum/A...050119-2-055283.html is the best w/p r&r thread on the form (Thanks Jazzman!) I did it from the top, no need to pull the wheel or wheel well. I kept track of which bolts were which sizes and show them on the drawing below:



Notes: None of the T-30 penetrate the water jacket, but they all need anti-sieze. I used thread sealant on all the rest, but I am only certain that #4 HAS to have it. #3 and #7 are studs and hold brackets which are in turn retained with 13mm nuts. #4 is unique in that it is BOTH T-50 torx AND 18mm hex.

I suggest using a plastic putty knife to clean the gasket surface since you cannot damage the aluminum with a plastic putty knife.

And in an OH NO! moment I discovered what you all probably already know: BRAKE cleaner leaves no residue, but CARB cleaner DOES!

This is a $600 flat rate manual job (on Long Island, NY) and well worth your time to do yourself!

regards and good luck,

Larry

Great information, if not a nod towards Jazzman.

Want to add, that when I did mine, I used this picture to reference where the bolts went. I printed it out, then just poked the bolts through the appropriate holes. No misplaced bolts, or wondering where any go.

------------------

Lots of people use this opportunity to switch everything over to standard Hex bolts; if I ever have to do this project again I think I'll make the switch.

I'd forgotten I posted on that old thread linked above but am happy to report all has been well these past six years. No leaks and no water pump issues at all.
