Any suggestions on how to remove the water pump pulley?? I removed the bolts but the damn thing won't come off. I have tried pulling, prying, and a lot of cursing, but all to no avail.

You mean i am supposed to remove those bolts?!?!?!

The bolts came out easy, but the damn pulley is stuck to the water pump. I have tried everything. Tomorrow i am going to see if i can hit it with a torch to heat it up a little, hopefully that will loosen it up.

I am beginning to think that the gentleman that sold me the car was a little dishonest in his reply to my "has the timing belt ever been changed?" question! That would put the original timing belt at 146k miles!

146K on the original timing belt!? That must be some sort
of record...and not necessarily one I'd want.

I'll assume you are replacing the old water pump, so
hitting it with a torch might do the trick as you don't
want to mangle your pulley too much. I've never heard of
one sticking tenaciously like the one you have, they
normally drop off after you take the four 10mm bolts out...
normally. Sounds like Liquid Wrench might not be much use
in this instance.

Make sure you clear the playing field as much as you can
(i.e. remove the coolant overflow tank and unbolt the
cruise control thingie and set it out of the way) if you
haven't already. It's pretty cramped in there as you've
probably noticed and you don't want to set that foam
cover on the A/C line on fire; that'd be a bad thing...

Good luck!

Update

Had a friend bring over a torch....hit the pulley with the heat for a minute solid...grabbed the pulley with a 13 inch pipe wrench and twisted for about twenty seconds with everything i had...nothing

Using a technique i discovered on a shampoo bottle, i repeated the process and after about 15 seconds of pressure, WHAM! The damn thing came off. Only problem is the pulley is destroyed. Its bent all over the place At least the repair process can procceed...for now!

Man, what did that guy do, superglue it together? I don't
think even superglue would've held up that long. The two
parts must have been corroded together (can't remember if
the water pump was aluminum, but I think it was) and maybe
that reacted with the steel in the pulley somehow, fusing
them together...

What was the shampoo trick? Might come in handy sometime
in the future...

Gnarled pulley...guess you'll be making a trip to the
salvage yard soon or maybe it's a standard size pulley
you can pick up at a parts store? I'd be coating the
inside of the pulley with a little layer of anti-seize
before I put it back on.
