IF YOU CONFIRM
A tapping noise coming from the dash area when the engine is running at operating temperature,
NOTE:
This tapping noise, if it should occur, sounds like a screwdriver being tapped on the work bench. The tapping speed increases and decrease with the
engine RPM and may require engine RPM of about 3000 for the noise to be heard.
DETERMINE IF
The noise is coming from inside the heater core (see Service Procedure).
ACTION
"Back-Flush" the heater core to remove gray silicone debris.
IMPORTANT:
The purpose of "ACTIONS" (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire Service
Procedure as it contains information that is essential to successfully completing the repair.
