Product Details

The Cardone Power Steering Reservoir line is focused on replacing the reservoir itself when the pump is not the source of the problem. On many vehicles, restricted flow, contamination, or a damaged reservoir can create noise, foaming fluid, or pressure concerns that are often mistaken for pump failure. Part number 3R-129 follows the original equipment layout and is designed for the Toyota Highlander power steering system used from 2001 through 2007. This part cross-references Toyota 4436048030 for the same application.

Common Problems This Part Can Address

• Power steering fluid foaming caused by trapped air or restricted reservoir flow
• Reservoir leaks from cracking in the body or hose tube areas
• Noise or cavitation traced to a clogged or damaged remote reservoir
• Loss of steering assist related to contaminated fluid circulation
• Heat-related plastic deterioration in the engine compartment

Installation Notes and Tips

On the Toyota Highlander, the reservoir location can vary by vehicle layout, but remote reservoirs are commonly mounted near the pump, on an inner fender, or on the firewall. Inspect the return and outlet hoses for cracking, debris, or fluid discoloration before installation. If the fluid is grey or black, or if debris is present, service the hoses and fluid as needed and bleed air from the system after installation to prevent foaming and cavitation.

Quality Assurance

Cardone manufactures this reservoir to match OE fit, function, and performance, using OE-grade materials and 100% testing to verify proper fit and leak-free operation. The design is intended to meet the filtration efficiency of OE reservoirs that use an integrated filter.
