How do you replace the power steering pump in a 1994 Jeep Grand Cherokee?

Answer 1

first remove the serpentine belt there is a tension pulley that you will see located on the left side of the engine. loosen the nut on the tension pulley and you will be able to remove the belt. once the belt is removed you will see the Power Steering pump has a big pulley on the front with three holes located on it. align one of the holes on the pulley with each of the three bolts that hold the power steering pump to the power steering pump engine mount bracket

remove the hoses from the power steering pump one will unscrew off the top of the pump(the high pressure side) the low pressure side is a bit more tricky as it is very very very easily broken. either cut the line and replace it when you replace the pump or else try and remove the end that is not attached to the pump on the low pressure side if you can. I usually just trim off about an inch of the hose just before it attaches to the pump with a pair of cutters. be aware that when you do so that power steering fluid will go everywhere and have a can or something to catch it in and a rag to clean up what slops out.

after you get the pump off put the whole dripping thing in a bucket or some other oil resistant container and take it to the automotive store and swap it for the core charge on a new power steering pump and buy more power steering fluid, make sure that you have them swap out the belt pulley and put it on the new pump for you and that you take the dipstick/cap when you swap out the old pump one for the new one. once you get back, take off any factory caps (they are usually red) from the pump where the hoses attach. now attach the pump back to the engine mount bracket and reattach the serpentine belt then reattach the hoses and retension the belt pulley make sure that you put power steering fluid back into the pump and top it off. then fire up the engine and make sure that you twist the steering wheel all one way and then all the other way then kill the engine and top off the power steering fluid again.

also i would like to say that (the poorly made piece of cast aluminum between the pump and the engine) the power steering pump mount bracket is prone to cracking and or breaking leading to the serpentine belt coming off from the engine and leaving you with a broken power steering pump mount bracket and bolts broken off in the engine block (I had my own power steering mount bracket made out of good ole steel) to fix the problem :) have fun
