Abstract
A multipurpose vehicle coolant recycling device is described. The multipurpose vehicle coolant recycling device includes a pump for pumping coolant through said recycling device, a processing tank for receiving used coolant, a fresh coolant tank for receiving fresh coolant, a filter for removing particulates from coolant, a coolant outlet hose constructed for attachment to a cooling system of a motor vehicle, a coolant inlet hose constructed for attachment to a cooling system of a motor vehicle, and a plurality of control valves for directing flow of coolant through the recycling device. The plurality of control valves are adjustable between a first configuration, a second configuration, a third configuration, and a fourth configuration. The first configuration is constructed for directing coolant from the fresh coolant tank through the pump and through the coolant outlet hose, and directing coolant from a cooling system of a motor vehicle through the coolant inlet hose and into the processing tank. The second configuration is constructed for directing coolant from the processing tank, through the pump, the filter, the coolant outlet hose, and into a cooling system of a motor vehic…
