Engine Cooling System: Maintenance: Notes
Periodic maintenance is necessary for extended cooling system and engine life. Engine and cooling systems are made of different metals, electrolysis begins to destroy the metals. Changing the coolant at scheduled maintenance periods reduces electrolysis and removes sediment.
Replace coolant at 36 months or 52,500 miles, and every 24 months or 30,000 miles thereafter.
CAUTION:
DO NOT
remove radiator cap while engine is running. Sudden release of pressure can cause boiling and hot steam release. Use extreme caution when removing radiator cap on warm engines.
