SOURCE: trying to locate water pump on my 2000 caddy deville

Its on the same side of the engine as the transmission, driven by the belt up top. It requires a special socket to remove the pump from the housing.(also, the pump turns clockwise to remove!)

I had a similar problem and a new thermostat. I removed the thermostat altogether to see if it was a problem and no more excessive heat. Bought another more expensive thermostat and problem cured.

Are you using a remanufactured pump? I had this problem with one, Had it on and off 3 times. Switched to a new pump, No more problems. I've used new pumps on these ever since. When they are rebuilt the reman company doesn't check the steel plate for flatness. If the last person who removed it bent it, It will never seal up. Try a new pump instead.

1992 Cadillac still Leaking coolant after water pump change.


Where does the coolant drip from? I had one and only one Cad from this era with the same problem. Turned out to be the recovery bottle cap would let go under operating pressure even though it passed the pressure tester test. Just one of those things.

98 cad deville is running at 210 degrees


Reverse flush the cooling system and put in fresh antifreeze to -20. (20 below zero). If that doesn't help, replace the thermostat.
