Cooling System Requirements

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 condenser or radiator will reduce the performance of the air conditioning and engine cooling systems. Refer to COOLING for more information before opening the engine cooling system, or attempting any service to the engine cooling system.
