Refer to Cooling System Specifications and Coolant Recommendations and Specifications in Section 10. NOTE: Use a mixture of at least 50 percent antifreeze and 50 percent water. NOTE (CFP83-F10, F20, F30 Only): Close the coolant vent when coolant level reaches the vent. Add coolant until the coolant level is just below the fill tube in the coolant heat exchanger. Check for leaks. Correct any leaks. Install the pressure cap on the heat exchanger.

Insufficient water supply will cause overheating, resulting in engine failure. Check that the pressure gauge isolation valve is open.
