Maintenance recommendations Maintaining the system Inspect all cooling system and heater hoses for deterioration, leaks and loose clamps. Service and replace as necessary. Cooling slots are provided in the front grille. Do not block airflow by placing any objects in front or behind these slots. Check air flow paths of the radiator for any foreign material. Clean these areas as necessary to maintain maximum cooling efficiency. When cleaning the radiator, always clean from the engine side of the engine compartment to ensure that foreign material is not jammed into the radiator fins. 13
