This is also the position that the valves are returned to after each procedure.
Fill New Tank 1. Turn all panel valves to the Home position. 2. Connect shop air to VCX Shop Air Coupler. 3. Turn all panel valves to the Fill New Tank position as shown in the illustration below. This orientation can also be obtained by positioning the panel valves toward the green highlights closest to each valve. 4. Place the Cone Adapter, with the Adapter Hose attached, into the container of new coolant. Open the Cone Adapter Valve to draw coolant into the New Coolant Tank. 5.
Empty Radiator 1. Run the vehicle with the heater turned on to bring the engine to operating temperature. Turn the engine off. 2. Turn all panel valves to the Home Position as shown on page 4. 3. Connect shop air to VCX Shop Air Coupler. 4. Turn all panel valves to the Empty Radiator position as shown in the illustration below. This orientation can also be obtained by positioning the panel valves toward the black highlights closest to each valve. 5. Insert the Adapter Hose into the Cone Adapter.
Empty Radiator (Continued) Waste Coolant Tank 6. Carefully remove radiator cap. Use a shop rag over the cap when removing to avoid injury in case there is still pressure. New Coolant Tank Cone Adapter Valve Hose Adapter 7. 8. 9. Place VCX Cone Adapter snugly into the radiator spout. Do not force the Cone Adapter into the spout, the suction pressure from the VCX should secure it adequately. Verify that the Cone Adapter Valve is in the open position.
Special Hookups Seal Tight Radiator 1. Insert the Adapter Hose into the end of the Cone Plug Adapter. 2. Place the Cone Adapter snugly into the radiator, coiling the excess length of Adapter Hose at the bottom. 3. Follow the Empty Radiator procedure steps 1-9.

Fill Radiator Fill Radiator MAKE SURE THE ENGINE IS OFF 1. Turn all panel valves to the Home position. 2. Turn all panel valves to the Fill Radiator position shown in the illustration below, this orientation can also be obtained by positioning the panel valves toward the magenta highlights closest to each valve. Verify that the Cone Adapter Valve is open. 3. New coolant is automatically pulled out of the VCX New Coolant Tank and into the vehicle radiator through the clear hose.
Top Off 1. Turn all panel valves to the Home position. 2. Turn the Cone Adapter Valve to the closed position. 3. WASTE COOLANT (PRESSURE) Open the Cone Adapter Valve to fill the radiator and overflow to the proper levels. 5. Turn all valves to the Home position. 6. Close the Cone Adapter valve when done. 7. Replace radiator and overflow caps. (VACUUM) EMPTY WASTE TANK EMPTY NEW TANK TOP OFF Turn all panel valves to the Top Off position as shown in the illustration.
Empty Waste Tank 1. Turn all panel valves to the Home position. 2. Connect shop air to VCX Shop Air Coupler. 3. Close Cone Adapter Valve. 4. Turn all panel valves to the Empty Waste Tank position shown in the illustration below. This orientation can also be obtained by positioning the panel valves toward the red highlights closest to each valve. 5. Place the end of the clear hose into a bulk waste container and open the Cone Adapter Valve. 6.

Troubleshooting Problem Vacuum becomes weak Solution Inside of the VCX, there is a venturi vacuum generator that may have collected debris during the operation of the unit. If this occurs, the vacuum will become weak resulting in a lower vacuum reading on the System Vacuum gauge and poor performance. Remove the venturi from the line and blow shop air through it. Use the Parts Identification (page 12) to locate the venturi. Reconnect to correct lines when done.
