Detailed Description
This Sunsong power steering return line hose assembly is made for the Acura RSX power steering return path from the pipe to the cooler. The hose uses CSM construction and is specified for return-side operation where heat resistance and stable fluid transfer matter more than high-pressure output. Sunsong 3405257 is a direct-fit replacement for 2002, 2003, 2004, 2005, and 2006 Acura RSX models in the pipe to cooler position.
The assembly is engineered to restore the original hose routing and connection style with 9.6 mm ID hose ends on both sides. This part cross-references Gates 352953 for the same application.
What It Helps Fix
- Power steering fluid seepage at the return hose
- Cracked or hardened hose material from heat exposure
- Restricted fluid return flow in the steering system
- Noise or uneven steering assist caused by a deteriorated return line
- Leak points at the pipe-to-cooler connection on the Acura RSX
Installation Notes and Tips
Verify the vehicle is a 2002-2006 Acura RSX with the pipe to cooler return-line layout before installation. Compare the hose length, end sizes, and routing to the original part before removal. Inspect adjacent pipes, clamps, and cooler connections for wear or corrosion so the new hose seals properly after installation.
Quality Assurance
Sunsong states that its return hoses exceed original equipment performance standards for low-pressure, high-temperature service. The tubing is manufactured from high-grade steel with a zinc electroplated coating to improve resistance to corrosion, rust, humidity, road salt, water, and grime.
