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 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.
