Sunsong 3604985 Power Steering Return Line Hose Assembly - Cooler Tube

Overview

The Sunsong 3604985 power steering return line hose assembly is built for low-pressure, high-temperature return flow service and is engineered for exact fit. It is a direct replacement for the return hose application on compatible Acura RL models and is made to restore worn wearable components to original condition.

Key Features

• Max working pressure of 250 psi for return-side steering fluid service.
• High-grade steel tubing with zinc electroplating for corrosion and rust resistance.
• Precision-engineered fit for consistent routing and installation.
• Includes brackets, grommets, heat shields, bushings, and protective sleeves as required.
• Compatible with Acura RL power steering return line hose applications.

Detailed Description

This Sunsong power steering return line hose assembly, part number 3604985, is designed for the return side of the steering hydraulic system where low pressure and elevated temperatures are common. The steel tubing is zinc coated to resist moisture, road salt, grime, and other corrosive exposure, helping maintain service life in demanding conditions. For Acura RL owners, this hose assembly provides a fit-focused replacement that addresses worn tubing and related wear items in one application-specific solution. This part cross-references Honda Genuine Parts (e.g., 53765SJA000) for the same application.

What It Helps Fix

• Leaking or deteriorated power steering return hose sections.
• Corrosion on exposed steering line tubing.
• Fluid seepage caused by worn hose routing components.
• Noise or steering performance issues related to restricted return flow.

Installation Notes

Verify the vehicle application and routing before installation. Match the hose assembly to the existing cooler tube configuration on the Acura RL and inspect adjacent brackets, grommets, and sleeves during replacement. Part number 3604985 should be confirmed against the original hose layout before service begins.

Quality Assurance

Sunsong manufactures this hose assembly to meet original equipment performance standards for return-hose service. The corrosion-resistant steel construction and precision fit support consistent replacement quality for the Acura RL application.
