- 1). Drain the radiator by twisting the drain plug at the base of the radiator in a counterclockwise direction with a wrench until the radiator fluid begins to exit from the center of the plug. Tighten the plug back into the radiator after the radiator is drained.
- 2). Remove the four bolts from the center of the fan blades with a wrench then pull the blades off of the water pump.
- 3). Disconnect the intake manifold hose, the heater hose and the lower radiator hose from the water pump. The intake manifold hose is located on the right side of the top of the water pump. The heater hose is just to the left of the intake manifold hose, and the lower radiator hose is located at the bottom of the water pump. Each of the three hoses attaches to the water pump with a band clamp. Loosen the screw on each band clamp with a flat head screwdriver then pull the hoses off of the water pump.
- 4). Disconnect the alternator brackets from the water pump. The alternator uses an upper and lower bracket, each of which is secured to the water pump with a single bolt. The opposite end of each bracket holds the alternator in place with a bolt. Loosen the bolts which hold the alternator to the upper and lower brackets, then rotate the alternator towards the engine to slacken the alternator belt. Pull the belt off of the front of the alternator, then remove the bolts which hold the upper and lower brackets to the water pump with a wrench.
- 5). Remove the bolts which secure the water pump to the front of the engine then pull the pump off of the engine.
- 6). Smear gasket sealer over both sides of the replacement water pump gasket then push one side of the gasket onto the back of the water pump. Position the water pump onto the front of the engine then install each of the water pump's retaining bolts with a wrench.
- 7). Position the upper and lower alternator brackets against the water pump, then install the brackets' retaining bolts through each bracket and into the water pump with a wrench.
- 8). Place the alternator's belt into the groove of the alternator's pulley then pull the alternator away from the engine to tighten the belt. Tighten the bolt which secures the bottom of the alternator to the lower alternator bracket with a wrench.
- 9). Position the fan blades onto the tip of the water pump then install each of the four fan blade bolts with a wrench.

Slide the intake manifold, heater and radiator hoses onto the water pump, then tighten each hose clamp with a flat head screwdriver. - 11
Remove the radiator cap and fill the radiator with a 50/50 mixture of water and antifreeze, then install the radiator cap.
