Detailed Description

Sunsong 3402912 is a steering return hose assembly made to replace the factory return line on 2009-2010 Chrysler 300 and 2009-2010 Dodge Charger vehicles with gear-to-cooler routing. The hose assembly uses a 16 mm male O-ring connection on one end and a 3/8 in. ID hose connection on the other, with a 52.8 in. length to match the specified application. Sunsong 3402912 is built with high-grade steel tubing and zinc coating to help resist rust and corrosion from humidity, road salt, water, and grime.

This part cross-references Four Seasons 55268 and Gates 365958 for the same application.

What It Helps Address

• Power steering fluid seepage at the return line
• Cracked, hardened, or deteriorated hose material
• Corrosion on the original return line tubing
• Improper routing or fitment from a worn steering hose assembly
• Noise or steering performance issues caused by restricted return flow

Installation Notes and Tips

Verify the vehicle routing before installation and confirm the gear-to-cooler configuration on the Chrysler 300 or Dodge Charger. Match the end styles and dimensions to the original hose path, and inspect nearby brackets, grommets, heat shields, bushings, and protective sleeves so the replacement restores the system to original condition where required.

Quality Assurance

Sunsong states that this return hose assembly exceeds original equipment performance standards for return-side steering service. The steel tubing is zinc electroplated for added resistance to corrosion and rust in harsh underbody conditions.
