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-2 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.
