RELIEVING RADIATOR PRESSURE

WARNING: Coolant in the vehicle cooling system may be extremely hot and

under great pressure. Wear safety glasses and use protective
clothing and gloves. Use extreme caution when removing radiator
cap and hoses.

NOTE: The MCX-2F does not need to be connected to power for the following.

The MCX-2F will relieve the pressure in a hot-car radiator by drawing a vacuum on the
overflow port on the radiator cap.

Shop air (55 to 100 PSI), connected to the rear port of the MCX-2F causes a vacuum
to be pulled on the small diameter clear hose, also connected to the rear. This clear
hose is connected to the overflow port on the radiator cap as shown above.

The system Vacuum Gauge on the MCX-2F control panel indicates the vacuum level
which will increase until the radiator cap opens and relieves the pressure. As the
pressure releases a small amount of coolant will be seen flowing in the clear hose.
When the pressure has been relieved, the radiator cap will again close and the vacuum
level will increase and become steady on the gauge.

The radiator cap can now be slowly and carefully removed.
