    NOTE:
    • Bleed air from the cooling system.
      • Start engine and let it run until it warms up (until the radiator fan operates 3 or 4 times).
      • Turn off engine. Check the coolant level and add coolant if needed. This will allow trapped air to be removed from the cooling system.
      • Put the radiator cap on tightly, then run engine again and check for leaks.
