Common Problems This Part Can Address

• Noise traced to a clogged or damaged remote reservoir
• Heat-related plastic deterioration in the engine bay
• Reduced steering performance caused by restricted fluid flow

Installation Notes and Tips

Inspect the reservoir location before ordering, since it may be mounted on the firewall, inner fender, or near the pump depending on the vehicle. Check the return and outlet hoses for cracking, debris, or internal breakdown, and replace worn hoses as needed. If the fluid is foaming, bleed air from the system after installation to prevent cavitation and pump damage. Confirm the system is clean before filling with fresh power steering fluid.
