Default Water Pump Leak

'92 SSEi
VIN1 Engine
155K Miles

OK. Thanks for the help so far guys... You're right, the tell tale sign of 'spray' marks on the underside of the hood tells me I have the exact same problem you did... that'* why my belt is delaminating so often.
So, after removing both of the belts, the engine mount bracket asmbly and the water pump pulley, I've discovered that I can access and remove all but one of the WP bolts. There'* one 1/2" bolt on the far left side of the water pump that is partially blocked by the idler pulley mounting bracket. This bracket seems to also attach all the idler pulleys, alternator and/or power steering pump. (I don't deserve this much fun.)
Does anyone have any suggestions on a quick and dirty solution to accessing that last bolt short of removing everything mentioned above (which seems like the only option...)?

Yep, it all has to come off because the alternator bracket has to be moved out of the way. When I discovered that while replacing my water pump, I couldn't believe it either.

Good luck.

I've spent the past hour researching this topic in various forums on this site and discovered that I'm in for a lot more fun just to remove that last WP bolt. What a great piece of engineering that was! It'* just that kind of lack-of-thought-preengineering-bone-headed-ness that keeps me from buying Fords (my apology to any Ford fanatics out there...)! I have to admit though, this is the first time I've really discovered anything this nasty in a GM car.
I guess I can forgive the GM gods for this blunder...

I'd say drill an access hole in case you need to do it again, but it'* in a bad spot.

It'* really not that much extra work. 30 minutes more.

Yeah, I thought the same thing... but did it the long way instead. It took anly about 5 hours start to finish... not to bad and everything went smoothly. She'* back up and running without leaks. If i need to dig into it again I'll probably take the shortcut and drill out the bracket.

Thanks for the help everyone. This is a great club to be a part of.

I recently replaced my pump as well. Yeah that is a real pain to take all of that off but if it needs done and you are willing to do it. The pain for me was getting the belts back on at the right tension but we got'er dun! I'm looking forward to tearing this engine down when i get an extra car.
Later.
