Abstract
A refrigerant fluid is placed within a driveline component, and in particular an axle housing. This refrigerant fluid is received within a sealed reservoir such that it is sealed from the typical lubricant in the driveline component. The lubricant heats the refrigerant through a housing such that the refrigerant vaporizes within the driveline component housing, thus cooling the lubricant. The vaporized refrigerant travels to a cooling chamber mounted remotely from the reservoir. The cooled refrigerant is cooled to a liquid state, and then returned to the reservoir. Preferably the cooling chamber is positioned on the vehicle frame vertically above the driveline component.
