How do you change a water pump on a 2000 Cadillac Eldorado
if you have the north star motor it on drivers side tward front grill, you will find a belt cover you need to remove an you'll need a special tool most auto parts stores will rent it to you for a small fee ,it likes a large socket ,if you have the new one you'll see how it fits in socket, using a rachet with socket place over water pump and turn a 1/2 turn to left and it's out ,replace in reverse ,take care not to disturb new o ring seal ,and don't use silicone to seal it , BUT general motors strongly suggest you do use some type of motor sealant , now for the bad news =these motors are very bad with over heating issues that have plaged the north star for years , if you drain antifreeze make sure you use air purge valves to remove any air from motor (purge valve looks like a brake bleeder screw ) or it will continue to over heat, im guessing that's why your doing this , if over heating is a problem take the time to go over all aspects of the cooling system =belts, flushing motor, cooling fans working correctly ,coolant filled, well I REALLhope this helps you ,good luck with it .
