NOTE: The MCX-2S does not need to be connected to power for the following.
The MCX-2S will relieve the pressure in a hot-car radiator by drawing a vacuum on the
overflow port on the radiator cap.
Connect shop air (55 to 100 PSI) to the port on the rear of the MCX-2S. This will cause
a vacuum to be pulled on the small diameter clear hose, also connected to the rear.
Connect clear hose to the overflow port on the radiator cap as shown above.
The system Vacuum Gauge on the MCX-2S 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.
Disconnect shop air from rear port.

SPECIAL HOOKUPS
Special Hookup 1) It may be necessary to reverse the hoses during the coolant
replacement procedure on the following pages for systems with
a reverse-connected thermostat. See note after Step 7 for the
symptoms of this situation.
Special Hookup 2) Some cooling systems do not have a cap on the radiator.
Instead, there is a single cap on the overflow tank as shown in
the illustration below.
The hoses to and from the overflow tank must be pinched using
hose pinching pliers during the coolant replacement procedure
on the following pages.
Failure to pinch these hoses will cause fluid to be forced out of
the vented cap on the overflow tank during the coolant
replacement procedure.

1. Determine the capacity and type of coolant for the vehicle cooling system. Refer to
the vehicle Owner’s Manual.
2. Make sure the New Coolant Tank (left slot on front) is filled with the correct coolant
and at a level higher than the amount required to fill the coolant system to full
capacity.
3. Check the Waste Tank (right slot on front) to make sure the level is low enough to
accept the full capacity of coolant in the vehicle cooling system.

CHANGING COOLANT TYPE
The MCX-2S has a means for easily using different types of coolants. A special feature
is the clearing process which purges coolant from the hoses and pumps prior to
changing the new coolant tank. The MCX-2S must be connected to a battery during
this procedure.
