Question about 2002 Cadillac Deville
Usually not, but bad bearings would.... it would be a squealing, or possible "grinding" noise. If the impeller has deteriorated (due to poor manufacturing materials), or a defective one was installed in the pump... it would generally cause the engine to run hotter than normal, but you would not hear any noise unless a piece of the impeller became lodged in the pump and the blades were hitting it. I have also heard of impeller blades becoming "Warped" (Due to cheap/defective parts being installed), which would cause them to hit the side of the waterpump casing and cause noise.

Yes, normally it does - sometimes (if you are lucky) it is only a loose belt which can be replaced and adjusted:

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.

Water pump is located on rear of the engine. faceing the car it is between the radiator and the head. It is driven by a small belt. It is removed by removing a cover plate that has the radiator host and by pass hose connected to it. it takes a special tool to remove and install this item. it is available at most auto stores. approx. 2 hour job and somewhat a hard job . see the haynes manual for this car very detailed on how to change the waterpump. jim

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.
