What It Helps Address

• Power steering fluid leaks from aged or damaged hose assemblies
• Hard steering caused by pressure loss in the steering circuit
• Noisy steering operation related to hose deterioration
• Incorrect hose routing after prior repairs
• Extended repair time from replacing pressure and return hoses separately

Installation Notes and Tips

Verify the vehicle year, engine configuration, and cooling equipment before installation. This assembly is listed for 2001-2003 Toyota Highlander with oil cooler and 2004-2007 Toyota Highlander applications; confirm the original hose routing and bracket locations against the removed part. Inspect mating fittings, seals, and surrounding steering components before filling and bleeding the system.

Quality Assurance

Each pressure hose is high-pressure tested before leaving the factory. The pressure hose is rated beyond original equipment performance targets, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure, and 1,600 lb tensile strength for durable service in the steering system.
