Water Pump - Inspect
A failed water pump may cause severe engine
overheating problems that could result in the
following conditions:
• Cracks in the cylinder head
• A piston seizure
• Other potential damage to the engine
Note: The water pump seal is lubricated by the
coolant in the cooling system. It is normal for a small
amount of leakage to occur as the engine cools down
and parts contract.
Visually inspect the water pump for leaks. Renew the
water pump seal or the water pump if there is an
excessive leakage of coolant. Refer to the
Disassembly and Assembly Manual, “Water Pump -
Remove and Install” for the disassembly and
assembly procedure.
