Water Pump: Service and Repair

Fig. 13 Water pump assembly:

REMOVAL

NOTE: With A/C, remove compressor and bracket

1. Drain the cooling system. Remove the V-belt.
2. Remove the nut and T-bolt that fastens the camshaft drive belt cover to the water pump. Disconnect the remaining hoses from the pump housing.
3. Remove pump and housing assembly. Four bolts hold the coolant assembly to the engine.
4. Disassemble the pump and housing assembly. Remove the pulleys from the water pump shaft. Remove the seven bolts and washers and separate the pump from the housing.

ASSEMBLY

Assembly is the reverse of disassembly. Use a new gasket between the coolant pump and housing. Tighten the seven bolts evenly until all are torqued to 87 in.lbs. (10 Nm). Install the pulleys. Torque the bolts to 15 ft.lbs. (20 Nm).

NOTE: The power steering pulley attached to the water pump is marked with the word KILMA. The mark faces outward (away from the pump) on vehicles with air conditioning, and inward on vehicles without air conditioning.

1. Clean the surface of the engine block where it will be contacted by the pump housing and the O-ring. Install a new O-ring in the recess that surrounds the water outlet. The O-ring between the water pump housing and the engine block does not require sealer.
2. Loosely install the water pump housing on the engine. The two short bolts are used at the top of the pump housing. Torque the four bolts evenly to 15 ft.lbs. (20 Nm). Refasten the camshaft drive belt cover to the water pump.
3. Install the hoses and refill the cooling system. Install and adjust the V-belt.
