Found this from answers.com.....1. Depressurize and drain the cooling system. 2. Loosen the alterantor adjustment and remove the belt. 3. Remove the water pump pulley. 4. Remove all the timing belt covers. 5. Loosen the timing (camshaft) belt tensioner and slip the timing belt off the camshaft toothed pulley (ensure you do not move the positon of the camshaft) 6. Unbolt the lower radiator hose fitting and heater retrun pipe. 7. Unbolt the waterpump from the block (5 bolts). 8. Remove all traces of the old gasket before mounting the new pump (Permatex spray on gasket remover works well). 9. Install the new pump and reassemble in reverse order to above.

    How do i change a water pump on 1996 grand cherokee limited V8


    I'll assume you have a 4.0l

    The 4.0L engine is equipped with a reverse rotation (counterclockwise) water pump. The word REVERSE is stamped or imprinted on the cover of the viscous fan drive and on the inner side of t he fan. The letter R is stamped onto the water pump impeller. When replacing water pump, ensure proper pump is installed. Installation of the wrong water pump will cause engine overheating.

    NOTE:On models with 4.0 L engine, front grill must be removed to access radiator draincock. Draining cooling system can be accomplished by removing drain plug from side of block as well as by loosening radiator draincock. Drain plug is located on lower left side of engine block.

    Disconnect negative battery cable. Drain cooling system. Disconnect electric cooling fan connector. Remove electric cooling fan and electric fan shroud assembly (if equipped).
    Loosen, but do not remove, 4 water pump pulley-to-water pump hub bolts and 4 viscous fan-to-idler pulley nuts. Remove accessory drive belt. Remove 4 viscous fan to idler pulley nuts, and remove fan and shroud together.
    Remove 4 water pump pulley bolts and remove pulley. Remove power steering pump and bracket. Disconnect heater hoses and lower radiator hose at water pump. Remove 4 water pump retaining bolts. Remove water pump.

    to install just reverse procedures

    Water Pump Leaking


    the hardest part of this job is removing your fan clutch. you removed your top fan shroud, then your fan clutch, its reverse thread. take off your belt, upper radiator hose and 6 10mm bolts hold it in. clean water pump housing and put all back together. aftermarket water pumps do not come with theermostat, dealer pumps do. remove your belt tensioner from old water pump 3- 15mm bolt, two different sizes and install on your new pump. you need, 10mm socket, 15mm socket, flat head screw driver, pliers to removed hose,fan clutch tool(rent at autoparts store)
