Engine Cooling System
CAUTION:
Avoid contact with moving parts and hot surfaces while working around a running engine in order to prevent physical injury.
NOTE:
Never use compressed air to pressure test a radiator that is not regulated to 138 kPa (20 psi). Pressures over 138 kPa (20 psi.) will damage the radiator.
Inspect the coolant and freeze protection fluid. If the fluid is dirty or rusty, drain, flush and refill the engine cooling system with new coolant. Keep the coolant at the proper mixture in order to ensure proper freeze protection, corrosion protection and engine operating temperature. Inspect the hoses. Replace the cracked, swollen, or deteriorated hoses. Tighten the clamps. Clean the outside of the radiator and the air conditioning condenser. Wash the filler cap and the neck. Pressure test the cooling system and the cap in order to help ensure proper operation.
