The tool is vacuum operated and requires a shop compressor for operation. The kit will work on BMW, Mini Cooper and most other vehicles. Kit includes an adapter which fits securely into the coolant tank or radiator filler neck. When activated the tool draws the entire cooling system and hoses into a vacuum. A built in shut off valve allows you to seal the system and hold it in vacuum, allowing you to check for leaks. If the system at this point does not hold vacuum, this is an indication of a leak in a hose, water pump seal, radiator or some other location. If the system does hold vacuum then that vacuum will draw fresh coolant into the system without starting the vehicle. The advantage is that leaks can be discovered and repaired without having to fill and drain the entire cooling system. Filling the system under vacuum also avoids trapped air pockets, which can cause thermostat malfunction.

Note: Requires Air Compressor
