COMPONENT DESCRIPTION Unpack all components and verify quantities per this illustration. Contact RTI if any items are missing or damaged.
SAFETY PRECAUTIONS WARNING: FAILURE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH. C Read and understand the Operation Manual completely before operating this unit. C Always wear proper eye and skin protection when operating and maintaining this equipment. C Take precautions to keep clothing, hair, hands, hoses, etc. away from all moving parts on the vehicle. C Automotive cooling systems can be under pressure and extremely hot.

CONNECTING TO THE COOLANT SYSTEM The MCX-2F can be connected to the cooling system in either of the configurations shown below. The choice is dependent on the ease of accessability to the hose connections. 1. Turn both valves on the front of the MCX-2F to EXCHANGE. 2. Disconnect the radiator hose from either the engine or the radiator. 3. Select an Adapter Hose with the same inner diameter as the radiator hose and connect at the point the radiator hose was disconnected using a clamp. 4.
SPECIAL HOOKUPS Special Hookup 1) It may be necessary to reverse the hoses during the coolant replacement procedure on the next page for systems with a reverse-connected thermostat. See note after Step 6 on next page 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.
ENGINE FLUSH The engine can be flushed with a chemical additive with the MCX-2F connected as described in preceding pages. Two valves located on the front panel each have two positions - EXCHANGE and BYPASS. When the valves are both turned to the BYPASS position the coolant in the vehicle bypasses the MCX-2F. It flows through the green and black hoses which are connected together inside the MCX-2F by the two valves being in the BYPASS position.
COOLANT REPLACEMENT Once the MCX-2F is connected as described on the preceding pages it is ready to replace the old coolant with new coolant.
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.
COMPLETING THE JOB All used coolant in the vehicle cooling system has now been replaced with new coolant. The following steps will complete the job.

CHANGING COOLANT TYPE he MCX-2F 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-2F must be connected to a battery during this procedure.

EMPTYING THE WASTE TANK The Waste Tank can be emptied two different ways. A. The Waste Tank can be removed from the MCX-2F and transported to the area where it is to be emptied. A quick connect coupler is installed on the black hose to make this disconnection quick and clean. B. The MCX-2F can be used to pump the waste coolant directly from the Waste Tank into another waste collection tank. A 12 volt battery will be required to power the MCX-2F.

WASTE PUMP IMPELLER REPLACEMENT The waste pump impeller may require periodic replacement. The concentration of impurities in recovered old coolant affects the life of the pump impeller. Changing the impeller is quick and easy as follows: 1. Remove Hose Holder on rear of unit to access the end of the Waste Pump. 2. Remove 4 screws. 3. Remove cover plate, gasket and worn impeller. 4. Coat new impeller with Vaseline® petroleum jelly. 5. Align flats and press impeller onto shaft. 6.
