A humming, whining noise is audible below 750 rpm. This noise is transmitted through the heater valve and can be heard from the driver's seat only with the coolant at normal operating temperature.

A squealing noise is audible at idle with the coolant at normal operating temperature. This noise is often mistaken for a dry or faulty alternator bearing. Diagnose the symptom carefully.

CORRECTIVE ACTION

Add the water pump lubricant listed under PARTS INFORMATION to the radiator coolant.

1. Allow the radiator to cool.
