Coolant Fill Procedure
Before filling the cooling system, read the “Coolant Specifications”
section to ensure using the proper antifreeze and coolant additive.
1. Close all drain cocks and replace all drain plugs.
2. Loosen the bleed screws on the upper coolant pipes.
3. Mix the coolant solution in a container with a capacity over 20 gallons as follows:
a. Pour 10 gallons of soft, clean water into the container.
b. Pour 10 gallons of ethylene glycol antifreeze into the container. The water and antifreeze
should be a 50/50 solution.
c. Pour supplemental coolant additive into the container. Refer to instructions provided by the
additive maker for concentration specifications. Take into consideration the concentration of
additive supplied by the coolant filter when determining how much liquid additive to add to
the coolant mixture.
d. Mix the water, antifreeze, and coolant additive thoroughly.
4. Slowly pour the premixed coolant solution into the surge tank. Fill the system until coolant runs
from the bleed screws in the upper coolant pipes.
5. Tighten the bleed screws, start the engine, and switch on the driver heater/defroster. Keep the
surge tank cap removed to allow the entrapped air in the system to be purged.
6. Stop the engine and replace the surge tank cap.
7. Run the engine again for at least five minutes. Then check the coolant level on the surge tank
sight glass.
8. Add coolant as necessary to top off the system. Open the bleed screws on the upper coolant pipe
to be sure only coolant comes out.
9. Tighten the bleed screws.
