Power Steering Fluid Cooler: Description and Operation
DESCRIPTIONThe purpose of the power steering cooler is to keep the temperature of the power steering system fluid from rising to a level that would affect the performance of the power steering system.
The cooler is placed in series with the power steering fluid return hose, between the steering gear fluid outlet port and the power steering fluid reservoir. It is mounted to the bumper reinforcement in front of the radiator. The cooler is secured to the power steering fluid return hose using standard adjustable clamps or crimp clamps.
OPERATION
The cooler used on this vehicle is referred to as a fluid-to-air type cooler. This means that the air flow across the tubes of the cooler is used to extract the heat from the cooler which it has absorbed from the power steering fluid flowing through it. The temperature of the power steering fluid is lowered prior to it entering the power steering fluid reservoir where it is resupplied to the power steering pump.
