you need to have a pulley puller to get the pulley off if you don't have one most auto zone part stores have a loan a tool program and they can help you with that on most powersteering pumps the high pressure line will be a fitting or bolt on and the return line is usually just a squeeze clamp hope this helps good luck

on my 1998 Deville its located in the trunk. the panel thats is butted up to the back of the rear seat. look for some black nuts around the top of rim of the trunk, they are about 1'' long, these have to be removed first... good luck.....

The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

maybe the water pump wasnt the problem to begin with. if the engine temperature only goes up when you stop the car then most likely it is the FANS that are not engaging to cool the radiator which is a problem with the fan sensor, computer that controls the fans, relay/fuse. I had the same problem on my 1999 cady STS coming back from my vacation. the engine temperature would be normal only when I drove the car above 70km/hr because the air passing through the front of the car would cool the radiator. when I slowed down the fans wouldnt start and no air was passing through to cool the rad, hence the engine temperature would start to go to HOT. good luck.
