C Read and understand the Operation Manual completely before operating this unit.
C Always wear proper eye and skin protection when operating and maintaining this
equipment.
C Take precautions to keep clothing, hair, hands, hoses, etc. away from all moving
parts on the vehicle.
C Automotive cooling systems can be under pressure and extremely hot. Allow the
cooling system to cool down and use extreme caution when removing caps and
hoses.
C Coolants are poisonous to people and animals and are also corrosiv e. Clean up any
spills immediately.

New Coolant
Green Hose
Tank Cap & Plug
Quick
Coupler
New Coolant Tank
(Small)
The MCX-2F has two tanks (plus an extra New Coolant Tank) which are installed and
connected from the rear. Quick connec t couplers are mounted on the hoses which
connect these tanks to the MCX-2F. A green hose connects to the New Coolant Tank
(right side) and a black hose connects to the Waste Tank (left side). The small
diameter black drain hose must be inserted into the hole in the cap of the Waste Tank.
1. Slide the New Coolant Tank to the rear and sit it on the floor.
2. Remove the tank cap and fill the tank with new coolant and water in the
proportion s specified by the coolant supplier. The tank can be disconnected
and moved to a bulk coolant storage area for filling if desired. A plug is
provided on the cap to prevent spillage during transport.
3. Replace the tank cap and position the tank in the MCX-2F. Make sure the
green hose is securely connected. Slide the tank to the front so the liquid level
can be seen through the front panel slot.
4. Make sure the plugs are removed from the caps on the Waste Tank and
the New Coolant Tank. This is required for venting the tanks during
operation. The small diameter black drain hose must be inserted into the
hole in the cap of the Waste Tank.
5. Fasten the clips on the tank strap to secure the tanks in the MCX-2F.

The MCX-2F control panel is illustrated above. Note that the bottom of all three
selector switches has been pressed which turns all functions off. Make sure all
switches ar e off before connecting the battery cable clips to the battery of the
vehicle.
WARNING: Handle battery connection cable with extreme caution. Batteries
generate explosive gases during normal operation. Working in
the vicinity of a lead-acid or other automotive battery is
dangerous. Wear eye protection. Never smoke or allow a spark or
flame in the vicinity of the battery. Do not connect the black
power clip to the negati ve post of the battery to avoid a spark.
1. Verify that all switches are in the off position.
2. Connect the red power clip to the “+” (positive) post of the vehicle battery. The
battery must be 12 volt.
3. Connect black power clip to an engine ground (not the negative post of the
battery).

RELIEVING RADIATOR PRESSURE
WARNING: Coolant in the vehicle cooling system may be extremely hot and
under great pressure. Wear safety glasses and use protective
clothing and gloves. Use extreme caution when removing
radiator cap and hoses.

NOTE: The MCX-2F does not need to be connected to power for the following.
The MCX-2F will relieve the pressure in a hot-car radiator by drawing a vacuum on the
overflow port on the radiator cap.
Shop air (55 to 100 PSI), connected to the rear port of the MCX-2F causes a vacuum
to be pulled on the small diameter clear hose, also connected to the rear. This clear
hose is connected to the overflow port on the radiator cap as shown above.
The system Vacuum Gauge on the MCX-2F control panel indicates the vacuum level
which will increase until the radiator cap opens and relieves the pressure. As the
pressure releases a small amount of coola nt wil l be seen flowing in the clear hose.
When the pressure has been relieved, the radiator cap will again close and the vacuum
level will increase and become steady on the gauge.
The radiator cap can now be slowly and carefully removed.
