waterpump replacement
How often should waterpumps be replaced? I took my waterpump off to change the gasket, and want to know how freely it should be spinning? It spins but has a bit of resistance... not notchy or worn, just not as smooth as say a ballbearing wheel from a skateboard as an example.
The pump looks in good shape, but I want to know if I should be able to spin the pump by hand and have it keep spinning with no resistance? What kind of bearing is used? Is it a plane or ball bearing?

I wouldn't worry about it unless it's making noise or your pulley has lateral play in it (as in you can wiggle it to-and-fro (with respect to the car, front-to-back). I had this problem and I chewed up a belt because of it. You can search for posts by me recently, as I replaced mine with an Mazmart RE-medy unit, which I have been very happy with so far!

No play...
and the RE-medy pump is a bit too rich for me right now... perhaps over the winter. I've been eyeing it up for a while. the only downside is I would have to get an idler pully since you can't run an under drive on them.

don't spend the money on the RE-Medy pump. I installed the pump and my car runs only 2deg. cooler. i must say that my car never ran that hot to begin with but i thought it would make a much bigger difference than it did. Unless you have $200 plus burning a hole in your pocket spend your money on something else!

The FD water pumps are VERY hardy. There's a weep hole at the front bottom of the water pump, if the bearings go water gets past them and weeps out that hole. That's the sign for a new pump.
You can get a LOT of life out of a stock pump. They'll easily do over 100k.

I agree with the others. The RE-medy WP is a nice piece and probably should be at the top of your list before tracking a car. But for the average (mildly modded) street car, the stock WP is adequate and RE-Medy pump would be expensive over-kill IMO.

The real test of the improved pump is the peak temps seen on a track, where minimum coolant temperature is irrelevant and the high RPM of the engine will not work with the stock pump.
