Finish Thompson CQC2 - Manual (Page 6)

CAUTION: Immediately clean up any spills. Damage to the
vehicle and equipment can result from the corrosiveness of the
coolant.
6. Wheel the CQC2 to the front of the vehicle and plug the electric
cord into a 115 volt, 60 Hz, grounded receptacle. Use a 16 gauge
(minimum) grounded extention cord if necessary.
NOTE: The CQC2 relies on gavity to fill the vehicle’s cooling system.
The TOP of the vehicle’s radiator must be LOWER than the BOTTOM
of the Fill Bucket on the CQC2 for the coolant change to occur.
USE OF THE EVACUATION PUMP:
WARNING: Automotive cooling systems can be under pressure and extremely hot. Allow the vehicle’s cooling
system to cool down and use extreme caution when removing caps and hoses. Consult the vehicle manufacturer for
recommended procedure on removing the radiator cap.
1. Squeeze the vehicle’s upper radiator hose to determine the amount of pressure in the system. If the hose is hot
and hard, allow the cooling system to cool down before proceeding.
2. Carefully remove the vehicle’s radiator cap.
3. Insert the Plastic Wand on the RED suction hose into the radiator. Turn on the CQC2 evacuation pump (the
Following these procedural guidelines will perform a Quick Change on most vehicles. Due to the variety of auto-
mobile, SUV and light truck cooling system designs, slight variations of this procedure may be necessary.
PREPARE FOR OPERATION:
1. Pull the vehicle into the service area. Set the vehicle’s heater controls to the highest temperature setting and
turn off the heater fan.
2. SHUT OFF THE VEHICLE’S ENGINE and raise the hood.
3. Verify that the fill valve on the green fill hose and the drain valve on the black drain hose of the CQC2 are both
in the CLOSED position.
WARNING: Wear proper eye and skin protection such as safety glasses and gloves.
4. Determine the total cooling system capacity of the vehicle. Prepare a mixture of new or recycled antifreeze
and water equal to the system capacity. Pour the mixture into the fill bucket. Place the lid onto the fill bucket.
NOTE: Most engine manufacturer’s recommend a mixture of 50% antifreeze and 50% water. Use distilled or
demineralized water to prevent scale and mineral build-up.
HINT: In cold winter months, mixing warm water with the antifreeze can help the coolant change occur more
quickly by helping to keep the engine’s thermostat open.
5. Check the level in the used coolant rum in the rear of the CQC2 to
verify that it is not too full to hold another coolant change.
