How do you remove and replace a power steering pump and reservoir for a 1998 Chevy S10?

I am going to answer this question as if you have the 4.3 Liter V6. The 2.2 will have a similar process but may require less disassembly. You will need to remove the top fan housing, remove serpentine belt, then unbolt the a/c compressor and set it to the side. Now remove the 4 bolts on the back of the fan itself to free the fan from the fan clutch. This will give you enough room to remove the rest of the components. Now you will need a pully puller to remove the pulley from the power steering pump. After you do this, you can unbolt and remove the steel piece that held the a/c compressor and power steering pump together. The power steering pump should be visible now. There are 2 bolts on the back of the pump that are somewhat difficult to get to (ratcheting box-end wrenches work great) that will free the pump. Now there are 2 hoses to remove, one is screwed into the back while the other is simply clamped on. You probably want an oil pan under the vehicle before you remove these since power steering fluid will spill out. Now if you purchased a new power steering pump w/ housing you can now swap them out and reassemble everything in the reverse order. If you have a power steering pump w/o a housing, you have to transfer the housing to the new pump. To do this, you will need to remove 2 stud/bolts from the back. Now you will probably need a vice to pull the old pump out of the housing because there is a rubber seal holding it in. Make sure all new gaskets are in place before reassembly. It's a good idea to at least partially fill the reservoir with power steering fluid before you start putting everything back together. This way you can check for leaks while the hoses are still accessible. Good luck.
