CHANGING COOLANT TYPE
The MCX-2HD 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-2HD 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 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.
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 the hose to a New
Coolant Tank with a different type of coolant.
