1. Loosen the bleed screw and fill the degas bottle with coolant until it begins to flow out of the bleed hole. Then, close the bleed screw.
CAUTION:Adhesives, stop-leak pellets or small foreign material in the motor electronics cooling system (MECS) can cause poor performance or
temporary blockage of the motor electronics pump. Only use clean, approved coolant when filling the system.
2. Turn the ignition to the ON position to actuate the motor electronics cooling pump and continue to fill the degas bottle to the correct level.
3. To bleed air from the system, loosen the bleed screw and allow air to escape while the M/E coolant pump is operating.
NOTE:Most of the motor electronics cooling system (MECS) air bleeding occurs as a normal process at the degas bottle through the vent tube; very
little occurs at the bleed screw.
