battery, remove bolts holding fan shroud, at the water pump where the
fan shaft attaches. Unscrew the nut. It will remove the fan from water
pump, lift out fan and shroud, 4 bolts holding clutch to fan.
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.
it is located in the block of the engine. Follow your radiator hoses to the block. The top is where your thermostat is and the bottom is where your water pump is. -------------start by taking off the shroud around fan blade, bolts on top of radaitor. pop in plugs on bottem. Shroud will slip by blade with radiator loose. Loosen bolts from tensioner and slip fan belt off Use a ratchet to take four bolts off of fan remove it set aside. Loosen all bolts from power sterring pump only one will have to be removed. From there you can slip out and replace water pump without much trouble. ------------this will help.
If you have the four flange bolts out, you may need to use a thin bladed screwdriver to separate the fan flange from the pump flange (a little wd 40 helps) There is no inch and a half bolt anywhere on the pump or fan so I have no clue what other bolt you are talking about. However, you likely are not removing the fan from the pump if you are working on an L6 engine. The pump does not have the fan mounted to it. Pump is bolted on the front of the block...lower hose goes to it.
