Detailed Product Information

Sunsong 3405226 is a power steering return line hose assembly made for vehicles that route the return hose from the steering gear. It uses CSM construction and is specified for low-pressure, high-temperature operation, making it appropriate for the return side of the steering system rather than the high-pressure feed line. This part number is also referenced in the aftermarket under Sunsong 3405226 for select Chevrolet Impala and Chevrolet Monte Carlo police package applications.

Compatible With 2006-2011 Chevrolet Impala, from gear, w/ Police Package; 2008-2011 Chevrolet Impala, from gear, w/ Cooler Tube, w/ Police Package; and 2006 Chevrolet Monte Carlo, from gear, w/ Police Package. The hose length and OE-style end configurations support a direct replacement approach for vehicles that need the correct routing and connection style.

Common Steering Problems This Part Addresses

• Power steering fluid seepage at the return hose
• Cracked or hardened hose material from heat exposure
• Incorrect hose routing on from-gear steering setups
• Loss of steering assist caused by return-side leakage
• Corrosion-related deterioration on the original hose assembly

Installation Notes

Verify the vehicle’s steering layout before installation, especially the from-gear routing and police package configuration. Confirm the end fittings match the existing connections: male O-ring at one end and ID hose at the other. Inspect nearby cooler tube routing, clamps, and surrounding components for wear before installing the replacement hose.

Quality Assurance

Sunsong states that this return hose exceeds original equipment performance standards for return-side service and is built to resist corrosion and rust exposure from humidity, road salt, water, and grime. The part is precision engineered for exact fit and is intended to restore worn wearable components to original condition where applicable.
