Built For Steering System Pressure

This power steering pressure hose assembly is designed around the original routing and connection points used on the Toyota Sienna. Sunsong 3402536 uses high-grade steel tubing with zinc electroplating for added resistance to corrosion from humidity, road salt, water, and grime. The hose is precision engineered for exact fitment and is subjected to high-pressure testing before it leaves the factory. This part cross-references Dorman - HELP 92432 and Gates 365841 for the same application.

Common Problems This Hose Can Address

• Leaking power steering pressure line on a Toyota Sienna
• Loss of steering assist caused by damaged hose construction
• Fluid seepage at the banjo or O-ring connection points
• Noise or inconsistent steering feel from a worn pressure line
• Corrosion-related hose deterioration in harsh road conditions

Installation Notes And Tips

Confirm the fitting style, hose length, and vehicle build date before installation. This hose uses a 16 mm banjo end and a 16 mm male O-ring end, so the connection points must match the original steering system layout. Inspect adjacent steering components, seals, and fluid condition during replacement to help restore proper operation.

Quality Assurance

Each Sunsong 3402536 hose is pressure tested at the factory to verify performance before shipment. The assembly is manufactured to meet demanding pressure and durability requirements for long service life in steering applications.
