Product Details

Built under Gates’ Pressure Line Assembly line, this hose assembly is engineered for power steering systems that require a precise pressure-side connection. The Gates 365540 uses a banjo fitting on one end and a female O-ring on the other, with 16 mm diameters to match the specified steering layout on 2000-2004 Toyota Avalon applications. The hose position is from pump, making it a direct replacement for the pressure line routing used in these vehicles. This part cross-references Dayco 92012 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks at the pressure hose
• Cracked or hardened hose material from age and heat exposure
• Damaged fittings or worn sealing surfaces at the pump connection
• Steering noise caused by pressure loss in the hydraulic line
• Reduced steering assist from a compromised pressure line assembly

Installation Notes and Tips

Verify the hose routing, end styles, and 16 mm connection sizes before installation. Replace the copper washers during service and inspect the pump, rack, and adjacent hard lines for wear, corrosion, or contamination. The included heat sleeves help protect the hose in high-temperature areas, and the anti-corrosion steel sleeve and zinc steel tube support long-term durability in the steering system.

Quality Assurance

Gates rates this pressure line assembly at OE performance and states that the rubber hose exceeds SAE J188 specifications. The Gates 365540 is built to meet the demands of hydraulic power steering service on Toyota Avalon applications.
