Cooling System

To maintain the performance level of the heating air conditioning system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or condenser will reduce the performance of the air conditioning and engine cooling systems.

The engine cooling system includes the radiator, thermostat, heater core, heater hoses and the engine coolant pump. Refer to Cooling for more information before opening or attempting any service to the engine cooling system.
