Detailed Description

This Sunsong power steering return line hose assembly is built to restore the return path between steering components on 1991-1993 Volvo 940 and 1991-1992 Volvo 740 applications.

What It Helps Address

• Power steering fluid seepage from a worn return hose
• Cracked or hardened hose material from heat and age
• Corrosion on original steel tubing and fittings
• Improper routing or fitment from a damaged replacement line
• Noisy or inconsistent steering caused by return-side hose deterioration

Installation Notes and Tips

Verify the original hose length, fitting style, and routing before installation. This assembly uses a 16 mm banjo fitting on one end and a 3/8 in. ID hose connection on the other, so matching the original connection points is important for correct installation. Inspect adjacent seals, clamps, and steering components for wear before reassembly.

Quality Assurance

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