I actually had an instance where my water pump cracked completely in half destroying my belts, radiator, fan clutch assem. etc.
The first step is to make sure you have a copy of the FSM -If you dont have a downloaded copy you can access one for a '95 Here.
http://www.nicoclub.com/FSM/J30/1995_J30/-remove the intake tubing-remove the radiator fluid, and the radiator(hoses and all)-remove all drive belts-now you should have enough room to remove the Fan clutch assembly from the water pump.- Next you have to remove the crank pulley. If you do not have an impact wrench small enough to fit in, you can use a large extended socket wrench. to do this, get back under the car and remove the starter and have a friend hold a "suitable tool" (flat head screw driver) in the teeth of the flywheel to lock it up. -you should then be able to loosen the crank bolt and use a pulley puller to remove the pulley.
- once that is done you can take of the timing belt cover and access the bolts for the water pump.
Install new water pump and put it all back together.
Good luck man, i'm not an expert but I do my best and mine has been running fine for the past 8 months.
