In Reply to: Water Pump Expert Needed!!! posted by Ed on March 06, 2001 at 03:18:58:
Seriously, I haven't dealt with the S14 water pump, in particular, but a water pump is a pretty simple thing.
There should be no clutch. It definitely sounds like you should replace your pump right away. Something has probably broken, internally. I have heard of the plastic impellers flying apart. If this happened, I don't know what other ramifications it could have, i.e. if there are little plastic pieces in your cooling system now. Maybe you should find out what you need to do if you take apart your pump and find the impeller "missing".
Replacement of the pump should be easy. There should be no special "bleeding" procedure. It should be the same as flushing your coolant, just with the r&r of your water pump in the middle. Get new gaskets, as usual. Someone else may have an opinion on "gluing" the gaskets to the water pump with gasket sealer. I'm not sure if this is required or advised.
I can post the torque specs and the exact procedure when I get home. That's around 1:00 GMT.
