Claim 3:
4. A system for controlling a temperature of an axle fluid, the system comprising:
an axle of a vehicle, the axle forming a cavity;
a volume of axle fluid disposed in the cavity;
a fluid cooling system in fluid communication with the cavity; and
a controller configured to sense a temperature of the axle fluid and selectively operate the fluid cooling system to cool the axle fluid when the sensed axle fluid temperature satisfies a first selected criteria and selectively cease operation of fluid cooling system when the sensed axle fluid temperature no longer satisfies the first selected criteria,
wherein the controller is operable to detect a viscosity of the axle fluid, determine whether the viscosity of the axle fluid satisfies a second selected criteria, and pass the axle fluid through a filter when the sensed axle fluid temperature does not satisfy the first selected criteria and when the sensed axle fluid viscosity does not satisfy the second selected criteria.
