This is the pump you want. It's the Airtex with the brass impeller. Sold here via eBay by bputah. I don't know what's up with the bputah web site so I now go on eBay and search under their user name bputah*com. It's $136 with free shipping. Or you can call bputah and order it 20th century-style.

When you get the belt off it's going to look like this
Went with one of these for mine a few months ago.

Looking at the photos online I'm convinced I can see the airtex one is better machined than those with steel stamped impellers. I'm also tending to think they will use a better bearing. I hope anyway.
Downside is wait time. They are not in stock yet. Job for next week.

Thanks Erik.
Those fans exploding. I remember that. I'm more inclined to believe that they may have been coming apart due to something else. For instance the water pump bearing finally giving out and slamming the fan into the shroud. Watching mine wobbling around. Or the shroud itself making contact with the blade. I dunno. Just my intuition.
Not wrong at all! Just means atleast one positive thing came from my misery. Haha
That is normal, but if your clutch is solid then I wouldn't worry about it. I would, however, worry about the fan if it's factory original. There was a slew of them on the forum a few months ago that exploded within weeks of each other taking out power steering pumps, radiators, fan shrouds, etc when they went. Old age got to them. Now, whether or not to put the old one back is up to you, but when all that went down I decided I wasn't going to be next and I spent about $70 to do an electric fan conversion. Gave me 1 mpg and peace of mind that I wasn't going to get stuck beside the road with a trashed engine bay. There's a link in my signature to the write up.
As for the off brand pump, I've heard of hit and miss results. I agree with... whichever user it was that just posted to buy the one with the brass impeller. I think Lucky 8 has them and they will likely give you a forum member discount. Can probably even do fast shipping for you, though you'll probably have to pay extra for that.

So, it's water pump day.
Finally get the fan nut off. First time. Tried jamming the rag inbetween the belt and pulley. Pulley was still slipping. Had to release belt tension with a spanner on the tensioner, so I could jam the rag in more, then it was held enough
Following my joy of that coming off. I realised I hadn't undone the pump pulley bolts. With a bit of messing about, they also gave up.
So, first question. The old gasket is RTVd. Some people say use a bit, some people say none? What's the latest?
Second. What's that electrical connection conveniently placed below the bit that might leak?
Oh, my pump was leaking through the the bearing, tiny bit, hadn't realised, thought it was my top hoses after inline stat I did.
Pump was horribly rough, and draggy.
Time to get busy with a blade to get the old gasket off. Grrrr. That looks boring.

Crikey. This gasket has turned into an indestructible ceramic style substance. Thought I'd be able to get at it with a Stanley knife blade. Doesn't want to know.
Any tips on softening it up? What can I spray it with?
Gotta be careful not to scratch the mating surface on the block.
I'm gonna have to go get one of those Stanley knife scraper type things.
The old gasket is in such good solid condition I wish I had just smeared a bit of RTV on it and reused it. Now I've started scraping I've got to finish it.
