    the threads on my water pump where the fan and pully bolt up are all fubared. the pump is still good and i don't want to have to buy a new one. i was thinking i would just drill out the holes and through bolt em but getting to the nuts on the back side will be nearly imposible with the pully on. what about a tap and die and go with the next size up in theads and bolt? anyone have to deal with this prob? thanks,

    First thing to do is chase the threads with a tap.

    Yep, I have a complete set of taps in my toolbox....and my truck nows that too...every bolt I replace, I have to chase it out with a tap (I think my truck is a whore). I've been replacing all the bolts with SS one..nice..
    I would try chasing it with a tap first, if its still not any-good get a heli-coil and drill it out..tap it..insert te coil and bang...

    Unless you have a fancy aftermarket pump, just buy a rebuilt one. Rebuilt GM water pumps only cost $25-30. /forums/images/graemlins/cool.gif That's way cheaper than replacing a hood, radiator, belts, hoses, etc. because the fan came off at 5,000 RPM. /forums/images/graemlins/eek.gif
