IMPORTANT! Read product Safety Data Sheet before use.
- Carefully read these operating instructions before beginning vehicle service.
- Before handling any BG product, read its Safety Data Sheet.
- A combination of mechanical and local ventilation should be used to prevent operator exposure to noxious fumes.
- 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 the cooling system. Use EXTREME CAUTION when handling hoses and adaptors on BG cooling system service machine as they can reach the same temperature as coolant.
- 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.
The BG Remote Tank Cooling System Adaptor Set is designed for use with a BG cooling system service machine to perform a BG Cooling System Service on systems with external pressurized overflow tanks. These overflow tanks are referred to as degas bottles, surge tanks or expansion tanks depending on the manufacturer. These systems are easy to identify because the radiator cap is located on the expansion tank instead of the radiator. The purposes behind this type of system are to provide a location for fill, provide an air space in the cooling system that allows the coolant to expand and contract, provide air separation during operation, provide a central air bleed location and replenish the engine coolant to the system.
On expansion tanks that have one 3/8˝or 1/2˝ hose coming off the top, replace the radiator cap with the appropriate BG radiator cap adaptor. Remove the 3/8˝or 1/2˝ hose, install barb with quick connect and plug bottle. Attach BG cooling system service machine pump hose (P) on one quick connect and attach the return hose (R) on the other quick connect. On BG cooling system service machine, turn V1 control valve to “N” to perform the fluid exchange. Examine the cooling system to make sure the new coolant is allowed to go through the radiator and the engine before returning to the expansion tank. There will be situations where a bypass hose will need to be pinched off to prevent the new coolant from bypassing either the radiator, the engine or both.
On the expansion tanks that have two 3/8˝ hoses coming off the top, remove the 3/8˝ hoses and install barbs with quick connects. Pinch off the hose going to the bottom of the expansion tank. Attach the BG cooling system service machine pump hose (P) on one quick connect and attach the return hose (R) on the other quick connect. On BG cooling system service machine, turn V1 control valve to “N” to perform the fluid exchange. Examine the cooling system to make sure the new coolant is allowed to go through the radiator and the engine before returning to the opposite quick connect. There will be situations where a bypass hose will need to be pinched off to prevent the new coolant from bypassing either the radiator, the engine or both.
