TEST COOLANT SYSTEM FOR LEAKS
The MCX-2 can be used to check the coolant system for leaks. The coolant system is
pressurized and the System Pressure Gauge on the MCX-2 is monitored for a drop in
pressure which would indicate a system leak.
The MCX-2 should be connected a shown above.
1. Turn control valve to TEST and press the top of FILL SYSTEM selector switch
to turn on the pump.
2. Watch the System Pressure Gauge and press the bottom of the FILL SYSTEM
selector switch when the pressure reaches 10 to 13 PSI.
3. The coolant system is now pressurized. Monitor the pressure for a constant
reading. A coolant system leak is indicated if the pressure falls.
