SET UP
The MCX-1 has two tanks (plus an extra New Coolant Tank) which are installed and
connected from the rear. Quick connect couplers are mounted on the hoses which
connect these tanks to the MCX-1. A green hose connects to the small New Coolant
Tank and a black hose connects to the large 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
proportions specified by the coolant supplier. The tank can be disconnected
and moved to a bulk storage and fill area 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-1. 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.
5. Fasten the clips on the tank strap to secure the tanks in the MCX-1.

CONNECTION TO POWER
The MCX-1 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 are
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.Weareyeprotection.Neversmokeorallowaspark or
flame in the vicinity of the battery. Do not connect the black
power clip to the negative 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).

CONNECTING TO THE COOLANT SYSTEM
The MCX-1 can be connected to the cooling system in either of the configurations
shown below. The choice is dependent on the ease of accessability to the hose
connections.
1. Disconnect the radiator hose from either the engine or the radiator.
2. Select an Adapter Hose with the same inner diameter as the radiator hose and
connect at the point the radiator hose was disconnected using a clamp.
3. Install Step Adapters in the Adapter Hose and the radiator hose using clamps.
Make sure the outside diameter of the Step Adapters is the same as the inner
diameter of the radiator hose.
4. Connect the Green and Black hoses from the MCX-1 to the two Step Adapters
as shown in the following illustration. See next page for special hookups.
5. Open the valves on the two Step Adapters.

SPECIAL HOOKUPS
Special Hookup 1) It may be necessary to reverse the hoses during the coolant
replacement procedure on the next page for systems with a
reverse-connected thermostat. See note after Step 6 on next
page for the symptoms of this situation.
Special Hookup 2) Some cooling systems do not have a cap on the radiator.
Instead, there is a single cap on the overflow tank as shown in
the illustration below.
The hoses to and from the overflow tank must be pinched using
hose pinching pliers during the coolant replacement procedure
on the next page.
Failure to pinch these hoses will cause fluid to be forced out of
the vented cap on the overflow tank during the coolant
replacement procedure.

If the pump is running and the new coolant level does not go down:
Try reversing the connections of the green and black hoses.
COOLANT REPLACEMENT
Once the MCX-1 is connected as described on the preceding pages it is ready to
replace the old coolant with new coolant.
Scales for the tank levels are
graduated in quarts and liters
1 Gallon = 4 Quarts.
1. Determine the capacity and type of coolant for the vehicle cooling system.
Refer to the vehicle Owner’s Manual.
2. Make sure the New Coolant Tank (left slot on front) is filled with the correct
coolant and at a level higher than the amount required to fill the coolant system
to full capacity.
3. Check the Waste Tank (right slot on front) to make sure the level is low enough
to accept the full capacity of coolant in the vehicle cooling system.
4. Turn control valve to EXCHANGE COOLANT.
5. Press the top of EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW
selector switch to turn on the pump.
6. Watch the level of coolant as it lowers in the New Coolant Tank. Press the
bottom of the EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW
selector switch when it reaches the correct level. This will stop the transfer of
coolant.

CHANGING COOLANT TYPE
The MCX-1 has a means for easily using different types of coolants. A special feature
is the clearing process which purges coolant from the hoses and pumps prior to
changing the new coolant tank. The MCX-1 must be connected to a battery during this
procedure.
1. Slide the New Coolant Tank to the rear and sit it on the floor.
2. Disconnectthegreen hose fromthetank andinstalla Step Adapteronthe end.
Close the valve on the Step Adapter.
3. Close the valve and install the Wand on the long green hose.
4. Turn control valve to FILL RADIATOR & OVERFLOW.
5. Press the top of the EXCHANGE COOLANT OR FILL RADIATOR &
OVERFLOW selector switch to start the pump.
6. Insert the end of the Wand in the fill port on the New Coolant Tank. Open the
valve on the Wand and then open the valve on the Step Adapter. All coolant in
the hoses and pump will be emptied into the New Coolant Tank.
7. Close the valve on the Wand and Step Adapter. Press the bottom of the
EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW selector switch
to turn off the pump.
8. Remove the Step Adapter from the green hose and connect a New Coolant
Tank with a different type of coolant.

The Waste Tank can be emptied two different ways.
A. The Waste Tank can be removed from the MCX-1 and transported to the area
whereitis to beemptied.A quick connect couplerisinstalled on theblackhose
to make this disconnection quick and clean.
B. The MCX-1 can be used to pump the waste coolant directly from the Waste
Tank into another waste collection tank. A 12 volt battery will be required to
power the MCX-1.
1. Install the Wand on the black hose.
2. Turn control valve to EMPTY WASTE TANK.
3. Press the top of the EMPTY WASTE TANK selector switch to start the pump.
