Water Pump: Testing and Inspection
WATER PUMP
INSPECTION
1. INSPECT WATER PUMP ASSEMBLY
a) Visually check the water hole and air hole for coolant leakage.
If leakage is found, replace the water pump assembly.
b) Turn the pulley, and check that the pump bearing moves smoothly and quietly.
If it moves roughly or noisily, replace the water pump assembly.
