How to replace water pump 1992 Jeep Cherokee?

Answer 1

Just did it this weekend. Auto Zone has pretty good basic online instructions/diagrams. Disconnect the negative battery cable. Drain the radiator (I didn't personally but most of the liquid was already spilt out or burned off.) Remove the Power Steering pump bracket on the front driver's side of the vehicle. There are two bolts in the back and a couple on the bottom that are hard to see (in addition to the obvious ones) that need to be removed to get the pump/bracket off. Also, there is one behind the steering pump, in the middle of the bracket that holds the bracket on and that one needs to be removed too. You may need to disconnect one or two radiator hoses if they are in your way. You'll need to remove the serpentine belt from the pump. Remove the extra fan (the one on the driver's side by the steering pump, NOT the main fan. Now you should be able to access the bottom radiator hose which you need to disconnect. Remove the four bolts that connect the pulley to the pump, I had a heck of a time with this one since the pulley moves and the bolts were in there way tight. It took lots of WD-40 and patience. You can try holding one bolt with a vice grip while turning a second with your ratchet. Personally, I had to push a screwdriver down into it to keep it from turning since the two wrench thing didn't work for me. (It might be easier to remove the pulley bolts with the belt still on if you can get to them that way- more resistance) Once the pulley is off you can remove the remaining water pump screws and then disconnect the metal hose screwed into the top of the pump. Scrape off any gasket residue, add a new gasket and reconnect everything in reverse order.
