CHANGING COOLANT TYPE
The MCX-2F 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-2F 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. Disconnect the green hose from 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 both valves on front of MCX-2F to EXCHANGE.
5. Turn control valve to FILL RADIATOR & OVERFLOW.
6. Press the top of the EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW selector
switch to start the pump.
7. Insert the end of the Wand in the fill port of 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.
8. 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.
9. Remove the Step Adapter from the green hose and connect the hose to a New Coolant Tank
with a different type of coolant.
