Power Steering Pressure Line Hose Assembly

Sunsong 3602307 is a power steering pressure line hose assembly built for direct replacement on select Toyota and Lexus applications. It is engineered for the tube-to-rack position and uses 16 mm male O-ring fittings at both ends for a precise connection.

Compatible With 2001-2008 Toyota Camry, 2004-2008 Toyota Solara, 2002-2006 Lexus ES330, and 2002-2003 Lexus ES300 in the tube-to-rack position. This part number, 3602307, is a fitment-specific solution for restoring steering system pressure routing on these vehicles.

• Max working pressure rated to 1,500 psi
• Burst pressure rating of 8,700 psi
• Tensile strength rated at 1,600 lb
• Steel tubing with zinc electroplating for corrosion resistance
• Precision-engineered fit for the specified vehicle applications
• High-pressure tested before leaving the factory

Detailed Fitment and Construction

This Sunsong pressure hose assembly is built with high-grade steel tubing and a zinc-coated finish to resist rust and corrosion from humidity, road salt, water, and grime. The hose is designed to restore the original routing and connection style on the Toyota Camry, Toyota Solara, Lexus ES330, and Lexus ES300 applications listed above. Part number 3602307 uses male O-ring fittings at both ends and measures 9.1 inches (231 mm) in length.

This part cross-references Dorman - HELP 80390 and Gates 363390 for the same application.

Common Steering Issues It May Address

• Leaking or damaged power steering pressure line
• Loss of steering assist from pressure loss in the hydraulic circuit
• Corrosion-related hose deterioration
• Improper fit from a worn or incorrect replacement line
• Noise or fluid seepage at the pressure line connection points

Installation Notes and Tips

Verify the vehicle year, make, model, and tube-to-rack routing before installation. Confirm both 16 mm male O-ring connections match the original line and inspect the sealing surfaces, brackets, and nearby components for wear or damage. Because this hose is application-specific, compare the original routing and length to the replacement part number 3602307 before final assembly.

Quality Assurance

Each hose is pressure tested at the factory before shipment to help ensure proper operation after installation. Sunsong states that this pressure hose assembly exceeds original equipment performance standards for pressure, burst resistance, and tensile strength.
