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