Changing Coolant Type - MAHLE MCX-1 Operation Manual

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. 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 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.

COOLANT OR FILL RADIATOR & OVERFLOW selector switch to turn off the pump.
