Power Steering Oil Reservoir Assembly
Mitsubishi FUSO®

The Power Steering Oil Reservoir Assembly (part number MK590330) is a component of a truck's power steering system. It is responsible for storing the power steering fluid that is used to lubricate and cool the system. The assembly typically consists of a plastic or metal container, a cap, and various hoses and fittings. The reservoir is located near the power steering pump and is connected to it by hoses. When the driver turns the steering wheel, the pump pressurizes the fluid in the reservoir, which then flows through the hoses to the steering rack or gearbox. The fluid helps reduce friction between moving parts and provides hydraulic assistance to make turning easier. Over time, the reservoir can develop leaks or cracks, which can cause a loss of power steering fluid and make it difficult to steer the truck. It is important to regularly check and replace any damaged components to ensure proper function of the power steering system.
