Remove the drive belt (see page 4-25). Turn the water pump pulley counter-clockwise. Check that it turns freely. Check for signs of seal leakage. A small amount of ''weeping'' from the bleed hole (A) is normal.

Remove the drive belt (see page 4-25). Drain the engine coolant (see page 10-6). Remove the crankshaft pulley (see page 6-12). Remove the oil cooler joint pipe (A), then remove the seven bolts securing the water pump. Remove the water pump (B). Inspect and clean the O-ring groove and mating surface with the water passage. Install the water pump with new O-rings in the reverse order of removal. Clean up any spilled engine coolant. Install the crankshaft pulley (see page 6-12). Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open (see page 10-6). aaa
