OPERATING INSTRUCTIONS

IMPORTANT! Read product Safety Data Sheet before use. Carefully read BG Xpress® Cooling System Fluid Exchange System instructions before attempting to place this system into operation on any vehicle. A combination of mechanical and local ventilation should be used to prevent operator exposure to noxious fumes. This machine incorporates parts such as snap switches and receptacles that may produce arcs or sparks. When located in a garage, this machine should be in a room or enclosure provided for purpose or should be 18 inches (46 cm) or more above floor. Keep all hoses and tools away from moving engine parts. Check all lines and adaptors for cracks and leaks before and after service. Use EXTREME CAUTION when removing radiator cap to prevent being burned by hot fluid escaping from cooling system. Use EXTREME CAUTION when handling hoses and adaptors on BG Xpress® as they can become as hot as coolant. Ensure that BG Xpress® S1 pump switch is in “Off” (O) position before connecting to power source. DO NOT dispose of any cooling system fluids or filters in a manner that is not in compliance with federal, state or local environmental regulations. BG Xpress® is designed to be used only with a vehicle cooling system service. DO NOT use BG Xpress® to pump or transfer any flammable or combustible liquids.

1. Make sure used coolant (U) hose is inserted into a waste fluid container.
2. Make sure S1 pump switch is set to “Off” (O).
3. Connect power cables to a 12-volt battery or other 12-volt power source.
4. Attach suction wand to pump hose (P) and place wand into a new or recycled 50/50 coolant supply.
5. Turn V1 control valve to “N.”
6. Turn S1 pump switch to “Remove” (–). This will fill BG Xpress® new coolant (N) container.
7. Turn S1 pump switch to “Off” (O).

1. Remove radiator cap and insert suction wand end of pump hose (P) as deep into radiator as possible.
2. Turn V1 control valve to “U.”
3. Turn S1 pump switch to “Remove” (–). Remove enough used coolant to allow for a dry removal of upper radiator hose, then turn S1 pump switch to “Off” (O).
4. Move suction wand to radiator overflow tank.
5. Turn S1 pump switch to “Remove” (–) to remove all used coolant from it.
6. Turn S1 pump switch to “Off” (O).
7. Clamp off upper radiator hose about 4–6 inches (10–15 cm) from end that connects to radiator. Remove upper radiator hose from radiator.
8. Determine correct sized adaptor and matching short hose/adaptor assembly needed for upper radiator hose. Screw CT700 adaptors into base unit—it makes no difference which adaptor goes into which end. Put loose clamp into place on hose—do not tighten.
9. Install CT700 adaptor between radiator and upper radiator hose and tighten all clamps. Be sure ball valve on connector hose is in open position (handle parallel to hose).

Note: CT700 is non–directional.

1. Install one 12 oz. (355 mL) bottle of BG Universal Cooling System Cleaner, PN 540, into mouth of radiator.
2. Insert suction wand into radiator.
3. Turn V1 control valve halfway between “N” and “U.”
4. Turn S1 pump switch to “Add” (+).
5. Turn V1 control valve slowly to “U” to avoid splashing coolant. Fill radiator.
6. Turn S1 pump switch to “Off” (O).
7. Replace radiator cap securely.
8. Start engine and run at idle 10–15 minutes to circulate BG Universal Cooling System Cleaner.
9. Stop engine and remove suction wand from end of pump hose (P).

1. Reverse BG Xpress® service hoses (P and R) at BG CT700, so pump hose (P) is attached to side opposite thermostat. Return hose (R) should be attached to thermostat side.
2. Open ball valve on CT700
3. Start engine and run until it reaches full operating temperature.
4. Close ball valve on CT700.
5. Turn V1 control valve to “N.”
6. Turn S1 pump switch to “Add” (+).
7. It will be necessary to pinch off small hose to recovery tank to prevent radiator cap from releasing coolant as thermostat closes and opens. Pump motor will also likely cycle on and off as pressure builds when thermostat closes.

1. Attach pump hose (P) to engine side of CT700.
2. Attach return hose (R) to radiator side of CT700.
3. Close ball valve on CT700.
4. Turn V1 control valve to “N.”
5. Turn S1 pump switch to “Add” (+).

1. Attach pump hose (P) to radiator side of CT700.
2. Attach return hose (R) to engine side of CT700.
3. Close ball valve on CT700.
4. Pinch off small tube that connects radiator fill neck to recovery tank. (Failure to pinch off this hose may allow cap to vent coolant under pressure to recovery tank causing it to fill and overflow.)
5. Turn V1 control valve to “N.”
6. Turn S1 pump switch to “Add” (+).

NOTE: If attempting to do service and pump stops or flutters (turns off and on repeatedly),* check for flow through service hoses. If there is flow, service will proceed without a problem. Fluttering can be stopped by moving control valve towards center position (do not completely shut off flow). If there is no flow, check quick coupler connections and verify thermostat location for proper flow direction.
*The BG Xpress® contains a pressure switch that is set to prevent over-pressurizing of cooling system. Motor will start again when pressure is released. If flow cannot be achieved with engine off, service can be performed with engine running.

1. When transfusion is complete, turn S1 pump switch to “Off” (O).
2. Turn vehicle engine off.
3. Open ball valve on CT700 to release any trapped pressure from engine.
4. Important! Allow engine to cool before removing radiator cap! Remove radiator cap.
5. Disconnect both service hoses (P and R) from CT700.
6. Attach suction wand to pump hose (P) and insert suction wand deep into radiator.
7. Turn V1 control valve to “N”.
8. Turn S1 pump switch to “Remove” (–). This will transfer new coolant in upper radiator into BG Xpress® new coolant (N) container.
9. Remove CT700 and reconnect upper radiator hose securely.
10. Add BG Universal Super Cool,® PN 546, to radiator.
11. Place suction wand back into radiator.
12. Turn V1 control valve half way between “N” and “U.”
13. Turn S1 pump switch to “Add” (+).
14. Turn V1 control valve slowly to “N” to avoid splashing coolant. Refill radiator with new coolant.
15. Turn S1 pump switch to “Off” (O).
16. Replace radiator cap securely.
17. Move suction wand to overflow tank and fill to normal level with new coolant.
