Engine Cooling System Inspection

ENGINE COOLING SYSTEM INSPECTION:
Inspect and test the protection against overheating and freezing. If the coolant is dirty or has a rusty appearance, drain, flush and refill with new coolant. Keep it at the 50/50 mixture specified. This provides proper freeze protection, corrosion inhibitor level, and engine operation temperature. Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Carefully clean the outside of the radiator and the air conditioner condenser to avoid damage to their fins. Wash the filler cap and neck. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.
