SET UP
The MCX-1 has two tanks (plus an extra New Coolant Tank) which are installed and
connected rom 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 loor.
2. Remove the tank cap and ill the tank with new coolant and water in the proportions
speci ied by the coolant supplier. The tank can be disconnected and moved to a bulk
storage and ill area i 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 ront so the liquid level can be seen through the
ront panel slot.

CONNECTING TO THE COOLANT SYSTEM
The MCX-1 can be connected to the cooling system in either o the con igurations shown
below. The choice is dependent on the ease o accessibility to the hose connections.
1. Disconnect the radiator hose rom 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 o the Step Adapters is the same as the inner diameter o the radiator
hose.
4. Connect the Green and Black hoses rom the MCX-1 to the two Step Adapters as shown
in the ollowing illustration. See next page or special hookups.
See next page or special hookups.See next page or special hookups.
See next page or 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 or systems with a reverse-connected
thermostat. See note a ter Step 6 on next page or the symptoms o this
situation.
Special Hookup 2) Some cooling systems do not have a cap on the radiator. Instead, there is a
single cap on the over low tank as shown in the illustration below.
The hoses to and rom the over low tank must be pinched using hose
pinching pliers during the coolant replacement procedure on the next page.
Failure to pinch these hoses will cause luid to be orced out o the vented
cap on the over low tank during the coolant replacement procedure.

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 t e tank
levels are graduated in
quarts and liters
1 Gallon = 4 Quarts.
1. Determine the capacity and type o coolant or the vehicle cooling system. Re er to the
vehicle Owner’s Manual.
2. Make sure the New Coolant Tank (le t slot on ront) is illed with the correct coolant and at
a level higher than the amount required to ill the coolant system to ull capacity.
3. Check the Waste Tank (right slot on ront) to make sure the level is low enough to accept
the ull capacity o coolant in the vehicle cooling system.
4. Turn control valve to EXCHANGE COOLANT.
5. Press the top o EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW selector
switch to turn on the pump.
6. Watch the level o coolant as it lowers in the New Coolant Tank. Press the bottom o the
EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW selector switch when it
reaches the correct level. This will stop the trans er o coolant.

CHANGING COOLANT TYPE
The MCX-1 has a means or easily using di erent types o coolants. A special eature is the
clearing process which purges coolant rom 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 loor.
2. Disconnect the green hose rom the tank and install a Step Adapter on the 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 o the EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW selector
switch to start the pump.
6. Insert the end o the Wand in the ill 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 o the EXCHANGE
COOLANT OR FILL RADIATOR & OVERFLOW selector switch to turn o the pump.
8. Remove the Step Adapter rom the green hose and connect a New Coolant Tank with a
di erent type o coolant.

EMPTYING THE WASTE TANK
The Waste Tank can be emptied two di erent ways
A. The Waste Tank can be removed rom the MCX-1 and transported to the area where it is to
be emptied. A quick connect coupler is installed on the black hose to make this
disconnection quick and clean.
B. The MCX-1 can be used to pump the waste coolant directly rom 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 o the EMPTY WASTE TANK selector switch to start the pump.
4. Hold the Wand over the Bulk Waste Container and open the valve.
5. Waste coolant will be pumped directly rom the MCX-1 Waste Tank into the Bulk Waste
Container.
6. The Waste Tank will empty and the pump will shut o . A loat switch in the Waste Tank
controls this unction.
7. Close the valve on the Wand immediately a ter waste tank is emptied.
8. Press bottom o the EMPTY WASTE TANK selector switch to stop the pump.
Note: The Waste Tank has a loat switch which detects when the tank is empty and shuts
