Finish Thompson CQC2 - Manual (Page 5)

The CQC2 is a device designed to perform quick
and simple engine coolant changes on automo-
biles and light trucks. When properly operated,
this quick change can be accomplished in as
little as ten minutes. The following is the normal
sequence of operation for a CQC. Refer to the
“Performing A Quick Change” section of this
manual for complete instructions before operat-
ing your unit.
PREPARE FOR THE QUICK CHANGE - A
vehicle is pulled into the service area and the
CQC is positioned. An appropriate amount of
new or recycled coolant is mixed in the CQC fill
bucket.
USE THE EVACUATION PUMP - Waste coolant
is removed from the vehicle’s radiator and
overflow bottle using the CQC2 RED suction
hose.
ATTACH THE CQC2 - The GREEN fill hose and
BLACK drain hose are attached to the vehicle’s
cooling system through a removed upper
radiator hose. No hose cutting or tees are
required.
PERFORM THE QUICK CHANGE - While the drain valve on the BLACK drain hose is closed, the Fill Valve on the
GREEN fill hose is opened and the vehicle’s engine is started. The upper house drain valve is opened, and the level in
the fill bucket will drop as the new coolant displaces the waste coolant. The waste coolant drains through the BLACK
drain hose and into the Waste Coolant Drum in the rear of the unit. When only two quarts of new coolant remain in the
CQC2 new coolant bucket, the fill and drain valves are closed, and the vehicle’s engine is turned off.
DISCONNECT THE CQC2 - The CQC2 is removed from the vehicle and the vehicle’s radiator hose is reattached.
TOP OFF - The radiator and overflow bottle are filled to proper levels using the GREEN fill hose. The engine is started
to check for leaks.
