Product Details

Cardone’s Power Steering Reservoir line is intended as a stand-alone replacement when the reservoir is the source of the problem, or as part of a broader power steering service. Part number 3R-308 follows the original equipment layout and material approach to help restore proper fluid storage and return flow in the steering system. This part cross-references Kia 571502G000 for the same application.

Compatible With 2006-2010 Kia Optima, N/A; 2007-2010 Kia Magentis, N/A; and 2007-2012 Kia Rondo, N/A. The white plastic reservoir is designed for remote mounting and is supplied with the cap, making it a practical replacement for a leaking, cracked, or clogged reservoir on these Kia models.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked reservoir body
• Foaming fluid caused by trapped air or restricted fluid return
• Noise related to a clogged or deteriorated remote reservoir
• Heat-related plastic failure in the engine compartment
• Poor steering system fluid circulation from reservoir contamination

Installation Notes and Tips

Inspect the outlet and return hoses before installation, since hose deterioration can contribute to leaks and contamination. If the fluid is grey, black, or contains debris, service the hoses and fluid as part of the repair. After installation, bleed air from the power steering system to reduce foaming, cavitation, and noise. Depending on the vehicle, the reservoir may be mounted on the firewall, inner fender, or near the pump.

Quality Assurance

Cardone manufactures this reservoir to OE design standards and tests each unit to confirm proper fit and function. The OE-grade material selection and heat resistance support consistent performance in demanding underhood conditions.
