SOURCE: 1990 cadillac deville need help water pump removal???

Water pump is located on the side with all the belts. Find the water pump pully and LOOSEN the bolts that keep the pully on the shaft of the water pump. Once they are LOOSEN remove the belt. Then you can remove the pully bolts the rest of the way. Pully MIGHT be stuck on there, a couple of taps should loosen it enough to where you can pop it off by hand. Now if I recall this vechile correctly, there MIGHT be another pully that will hinder you. It's just easier to take it off right away. It's right above the water pump. I BELIVE it's an idler pully. Dosn't do anything but to help keep the belt on it's correct path. There should be one bolt in the middle of this pully, undo the bolt and pully will pop off. Make sure you REMEMBER how it was on. So that you put it back on the right way. Then, there are 2 or 3 different sized bolts that keep the water pump on. Remove the bolts, one at a time, and make sure you REMEMBER where they went. If you remember now, it will save time guessing later. Ok, once you are sure that ALL the bolts are removed, you can try to pop off the pump. If it dosn't come by hand, use a screw driver to pry a corner up and then do the rest by hand. Once it's off, it's time to clean the motor side of the pump. See, on these cars it's not a complete pump like it use to be, it's a half pump. Meaning, when you look at one side you can see the fins that move the water. Anyways, when you are at the parts store, pick up some emery cloth. It's sort of like sand paper. Well, once the pump is off, use a razor blade and scrape off the silcone that's on the block. Then use the emery cloth to make is nice and clean getting all of it off. Once that's complete, put the new gasket on the pump and reinstall. Put all the bolts in BEFORE tighting them down. And when you do tighten them, do it by hand! Using an air tool will break the bolt or strip the threads in the alunimium block and then it has to go to a mechanic. Once all the bolts are tight fill up the reservor to check for leaks. Also go back over the bolts one more time and make sure all are tight. Doing this now, will save you headace later. Then put the rest of the things back on in the order you took them off. That's it exepct for bleeding the cooling system. I assume you know how to do this, if not, let me know.

This can be a major operation. Go to public library and see if they have a chilton repair book on this car. The pump has about twenty bolts af various sizes and torx head bolts.

Why does my 2001 cadillac deville keep running hot. ive changed the water pump and the thermistat


Well there could be a couple of problems if you live in a hot place you should change the thermostat to a lower tempatured one so the water will circulate sooner that will help it run cooler if that doesn't do it it might need the radiator flushed.

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!)
