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.
2.
Press the top of EXCHANGE COOLANT OR FILL RADIATOR & OVERFLOW
selector switch to turn on the pump.
3.
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.
4.
The coolant system is now pressurized. Monitor the pressure for a constant
reading. A coolant system leak is indicated if the pressure falls.
