Symptoms & Diagnosis
Warning Signs of a Failing Engine Water Pump
Overheating engine
Temperature gauge rising into the red zone
Coolant leaks near the front of the engine
Whining or grinding noises coming from the engine
Steam coming from under the hood
Sweet smell of coolant
Testing the Engine Water Pump
Check for Coolant Leaks: Look for signs of coolant leaking around the water pump area.
Inspect the Water Pump Pulley: With the engine off, check the water pump pulley for play or wobble. Excessive movement indicates a worn bearing.
Feel the Radiator Hoses: With the engine running (carefully!), feel both the upper and lower radiator hoses. They should both be hot. If one is cold, the water pump may not be circulating coolant properly.
Listen for Noises: Listen for any unusual noises, such as whining, grinding, or rattling, coming from the water pump area.
Pressure Test the Cooling System: A cooling system pressure test can reveal leaks in the system, including the water pump seal.
Common Causes of Engine Water Pump Failure
Worn bearings due to age and mileage
Corrosion from contaminated coolant
Cavitation caused by air in the cooling system
Seal failure leading to coolant leaks
Impeller damage from debris in the coolant
Buyer's Checklist
What to Look for When Buying an Engine Water Pump
Material Quality: The water pump housing and impeller should be made of durable materials that can withstand high temperatures and pressures.
Bearing Quality: The bearings should be smooth and free of play.
Seal Integrity: The seal should be in good condition and free of cracks or damage.
