Detailed Description

Sunsong 3405245 is a power steering return line hose assembly engineered for the return side of the steering system, where fluid moves from the gear to the cooler. The hose is built to meet original equipment performance expectations and uses materials selected for durability in demanding underhood and undercar conditions. Its steel tubing is electroplated with zinc to help protect against corrosion, while the CSM hose section is suited to the heat and pressure conditions found in return-line service. If you are replacing a worn or leaking steering return hose on a Chevrolet Camaro or Pontiac Firebird, this part number 3405245 provides a direct replacement path.

This part cross-references ACI 81284 for the same application.

Common Problems This Part Can Address

• Power steering fluid seepage or leakage at the return line
• Cracked, hardened, or deteriorated hose material
• Corrosion on the steel tube section of the steering line
• Restricted fluid return from the steering gear to the cooler
• Noise or poor steering feel caused by a compromised return hose

Installation Notes and Tips

Verify the routing from gear to cooler before installation and compare the end fittings to the original hose. Inspect nearby clamps, seals, and connection points for wear, and replace any damaged sealing surfaces before filling the system. After installation, check for leaks with the engine running and cycle the steering from lock to lock to confirm proper fluid circulation.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for low-pressure steering return applications. The combination of zinc-coated steel tubing and CSM hose material is intended to support corrosion resistance and long-term service in harsh road conditions.
