For cooling system capacities not shown, the required amount of antifreeze can be calculated, using the following: Ethylene-glycol-base antifreeze in a 25%
solution protects to 10°F (12°C), 33% to 0°F (–18°C), 40% to –12°F (–24°C), 50% to –34°F (–37°C), and 60% to –62°F (–52°C).
†
60% ethylene-glycol-base antifreeze and 40% water by volume gives maximum coolant protection (–62°F [–52°C]). Exceeding 60% antifreeze diminishes
coolant protection; concentrated ethylene-glycol-base antifreeze will freeze at approximately 0°F (–18°C).
Table 3, Maximum Coolant Protection in °F (°C) at Various Antifreeze Concentrations
NOTE: You can mix purple-pink coolant (pre-
charged with a borate/nitrate-based additive)
with the common green coolant, although some
color change will be apparent.
14. Replace the surge tank cap(s).
15. Return the hood to the operating position.
16. Start the engine and turn on the cab heater.
Allow the engine to warm up to normal operating

leaks. Repair as needed.
17. Shut off the engine, then check the coolant level
in the surge tank. Add coolant if the level isn't
between MIN and MAX lines on the surge tank.
