•Engine overheating
•Whining or grinding noise from the engine area
•Steam or coolant odor from the front of the engine
•Low coolant levels after refilling

Diagnostic Steps

1
Check for visible coolant leaks around the water pump and hoses.
2
Ensure coolant level is at the proper mark; refill if necessary and monitor for rapid loss.
3
Start the engine and listen for unusual noises from the water pump area, such as whining or grinding.
4
With the engine running, feel the water pump for excessive vibration, which may indicate bearing failure.
