water pump replacement-won't budge

[DIGBY67]

me again...
Everything I've read on the posts says the water pump should just twist clockwise to release.
However, mine isn't budging AT ALL.
I have a water pump wrench (cheapo Lisle model), but it wants to slide off the flanges.
I've kept it on long enough that I've been able to apply enough pressure that I think should have broken it loose by now.
Anyone else experience this? More success with another tool (brand?)?
Am I missing something?
Thanks to all.

Try the one made by Owatonna Tools.

If it's stubborn to remove, apply heat. A heat gun like you use to strip paint works best, be very careful if using a propane torch.

I had the same experience. Everyone says how great the setup is. I thought it sucked compared to the old way of doing things. I bought the Lisle tool also and proceeded to bust the corners off the thing after much fighting. Had a shorter battle to get things to line up when installing it also.
I ended up basicly cutting it apart with a dremel tool using a 1/8" carbide bur. Kept a small magnet handy to clean out the shavings as I worked. It was a true pain in the ass.
Snap On also has a better tool from what I've heard, for something like $70.
I replaced all the hoses and water pump belt while I was there. Don't forget to put the Bars Leak Gold tablets in one of the hoses.
Good luck!

Thanks to all who've responded so far.
Looks like I'll be praying that the heat gun works, then an upgraded tool, otherwise it sounds like surgery unless someone else has had other means of success.
I did buy a new belt, but I have another post asking how to put it on...looks like a really tight squeeze around the bottom of the tensioner.
I'd appreciate some pointers on that procedure also from someone who's done it (Sweetwilliam?).
Thanks again to all.

That's a peice of cake. Remove the nuts that hold the gaurd for the pulley/belt on. Remove the gaurd. Then the studs that the nuts came off of are bolts that hold the tensioner assembly on. Remove it, drop in the new belt, done.

Thank you sir, I'll look at that ASAP...didn't want to make matters worse.
It'll probably be the weekend before I can do any work on this project.
Please keep the suggestions coming until then.

I tried to take the water pump off with the special wrench, but I proceeded to break off some of the tabs. I took it to the Olds garage and they had to machine it out (whatever that means). Of course they blamed me for the damage, even though they would have done the same thing (at least that's what I told myself). Sometimes it pays to take it to a technician, even though I hate to.

[DIGBY67]

My concern about breaking something was why I stopped banging on the end of my wratchet with a hammer...(Homer says DOHHHHH!)
I then extended the wratchet handle with a pipe to add leverage...no good...won't budge.
I'm really hoping the heat or another tool will work because this thing is dead in my driveway and won't make it to a mechanic on its own.

I have heard that an impact wrench will bust it lose. I guess there is room in there with the air box gone.

When our waterpump was replaced at the dealership, they said the water crossover had to be removed because the pump wouldn't come out with the standard tool. The pump is mounted in the crossover casting.

That's correct, if applying heat doesn't help free up the pump the only alternative is to remove the crossover casting and work on it 'on the bench'.

I looked at taking the crossover off mine, but that looked like a real drag to do. That's when I busted out the dremel tool. It took an hour or so to cut it off, but I "got er done".

[DIGBY67]

NOOOooooo! I saw that crossover-looks like the engine would have to come out.
A coworker also suggested an impact wrench, but I don't have one.
I think I can get my hands on a heat gun tomorrow, but I don't know if I can get to try it until Saturday. If I can get a long enough cord for a light and the gun I'll try it.

The waterpump went on my 95, & from looking at these posts,there`s NO WAY i was gonna buy a special tool that still may not work, THEN have to fight with it! I took it to a local reputable shop & he changed it for me for $180 total & even replaced my thermostat that i had already bought.
SAVE YOURSELVES ALOT OF TROUBLE & JUST COME OFF THE $180 & let SOMEONE ELSE fight this monster.
It was fabulous, i didnt have to lift a finger.
