Type of Vehicle: 2000, Ford Pickup F150, 4.2L

Title of failing part:

Defroster Inoperative, Replaced Thermostat Housing Gasket

Customers’ complaint:

The customer states the defroster is inoperative.

Cause of problem:

Confirmed the customer’s complaint and found the defroster was inoperative. Performed an inspection of the engine cooling system and found the engine coolant was below operating level. Filled the engine coolant to the proper operating level, attached a pressure tester to the engine cooling system, and pressurized the system to check for leaks. The engine cooling system did not retain the applied pressure, which indicated an engine coolant leak was present. Continued to apply pressure to the engine cooling system, inspected the system for signs of an external engine coolant leak, and found engine coolant leaked from the thermostat housing. Removed the thermostat housing and found the thermostat housing gasket was damaged.

Solution to the problem:

Replaced the thermostat housing gasket and verified the vehicle operated properly. The customer’s concern did not return.
