Finish Thompson CQC2 - Manual (Page 7)

1. Loosen the hose clamp that holds the UPPER radiator hose to the thermostat housing on the engine. Use a
nut-driver, screwdriver, or hose clamp pliers (depending on the type of clamp) to loosen the clamp.
2. Pull loose and remove the UPPER radiator hose from the vehicle’s thermostat housing inlet. There may be
liquid in the hose - place a supply of rags under the hose to catch any spilled coolant. Be careful not to dam-
age radiator hose while removing.
3. Attach the GREEN fill hose from the CQC2 to the removed, open end of the UPPER radiator hose by inserting
its Step Adapter into the UPPER radiator hose. With a hose clamp, seal the UPPER radiator hose tightly to the
“best fit” step on the step adapter.
CAUTION: Never allow the evacuation pump to operate without liquid. Running the pump dry will cause
premature wear or damage to the pump and is not covered under warranty.
4. Locate the vehicle’s coolant overflow bottle and remove its cap. Insert the plastic wand on RED suction hose
into the overflow bottle, turn on the evacuation pump, and remove as much liquid as possible. Turn off the
pump and return the RED suction hose to its hose clip. Replace the cap on the overflow bottle.
HINT: If the overflow bottle contains sludge, loosen it with water sprayed from a hose.
ATTACH THE CQC2 TO THE VEHICLE - CONVENTIONAL COOLING SYSTEMS:
1. Loosen the hose clamp that holds the UPPER radiator hose to the radiator.
Use a nut-driver, screwdriver, or hose clamp pliers (depending on the type
of clamp) to loosen the clamp.
2. Pull loose and remove the UPPER radiator hose from the vehicle’s
radiator. Be careful not to damage the radiator inlet or hose while
removing.
3. Attach the BLACK drain hose from the CQC2 to the removed,
open end of the UPPER radiator hose by inserting its step adapter
into the UPPER radiator hose. With a hose clamp, seal the UPPER
radiator hose tightly to the “best fit” step on the step adapter.
HINT: In some cases, the size difference between the UPPER
radiator hose and the step adapter may seem too large. It is OK
to tighten down the hose clamp to seal up to a 1/4" gap. A “worm-
gear” type clamp tightened with a nut driver works best.
4. Attach the “best fit” flexible hose adapter to the radiator’s inlet and
secure it tightly using the supplied hose clamp. Be careful not to
damage the radiator’s inlet.
5. Attach the GREEN Fill Hose from the CQC2 by inserting its step
adapter into the open end of the flexible hose adapter. With a
hose clamp, seal the flexible hose adapter tightly to the “best fit”
step on the step adapter.
CAUTION: Check and assure that all hoses, rags, tools, or other objects will be clear from moving parts of the
vehicle.
ATTACH THE CQC2 TO THE VEHICLE - SPECIAL COOLING SYSTEMS:
HINT: Some vehicles with non-conventional cooling systems require a different procedure for attaching the
CQC2. Some examples are:
•
Mid or rear engine vehicles with the radiator in the front of the vehicle.
•
Radiators that do not allow access to the upper radiator hose.
•
Pressurized overflow systems where the overflow bottle is capped, not the radiator.
