TEST COOLANT 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 a 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.
