Water Pump Pulley - Studs vs no studs

Water pump leaked like a sieve during pressure test, left me with just over a gallon in radiator. Firestone wanted $400 plus to do it and one of the 'mechanics' was insisting that they replace my (working) tstat.
I dismantled everything with the pump ready to pull out (hanging by a heater hose) as it got dark...will wait for daylight.
Question - why does the original have studs on which the fan pulley will mount while none of the replacements at Autozone, Quadratec, NAPA, etc. show them in pics? How do I mount my fan now?


Wrenching isn't the problem, it's the brains attached to the hands...unfortunately, I'm lacking some of the former so that's why I'm asking you guys!!

You need to remove the studs from the old waterpump. If you look at the instructions that came with the new waterpump it will say that. Double nut the studs and then turn them out. I just did mine today but it was leaking worse so I have to take back apart tomorrow...also got too dark to finish.

I can't pull the water pump past the steering pump. Any ideas?

you need to take the bolts out of the bracket that bolt into the waterpump and make sure the other bolts for the ps pump are loose. Just took mine back out this morning...make sure you put the gasket on correctly otherwise the hole for the passage at the top left is offset slightly and will leak like a biotch!

BTW, that PS bracket makes it a ***** to remove the WP. I'm sure it makes it difficult to install

replacement came with a gasket, looks like cardboard and no mention of self sealing or not. should I use RTV?

Yes...rtv both sides...just finished mine and no leaks but I found out why it was running with no thermostat...the radiator must be shot! Temp gauge went to the red now when I took it out. Everything else is new! Arrrggghhh!

I just bought new studs at Autozone. They have a kit with the studs and nuts that go on them for the fan clutch. I think the kit was $5.

I used that aviator gasket maker on mine so I didn't have to wait for the RTV to setup before filling the system up.

Took Dtn8r's advice, studs were easy to switch off of old onto new pump.

I forgot to look for that...next time!

As the nuts and studs are between the fan clutch and pulley, how do you set the torque? I can't fit a ratchet or torque wrench in that space!
Also, what are the torque settings for the power steering pump mount bolts?
