Keep power steering fluid flowing back through the system with the Sunsong power steering return line hose assembly, part number 3403984. It is a direct-fit replacement for the 1999-2005 Hyundai Sonata and 2001-2005 Kia Optima, and it carries low-pressure return fluid in the from-gear, gear-to-cooler position. See the Buyer's Guide tab for engine-specific fitment.
- Rated for return duty: Sunsong return hoses exceed original equipment performance standards. They have a maximum working pressure of 250 psi and are suited to low-pressure, high-temperature operation.
- Precision-engineered fit: Return assemblies are engineered to exact fit. They include the additional components Sunsong specifies to bring the wearable parts back to original condition.
- Corrosion-resistant tubing: The tubing resists corrosion and rust from high humidity, road salt, water, and grime.
- Pressure-tested: Every return hose goes through a high-pressure quality assurance test before it leaves the factory.
Sunsong is a vertically integrated manufacturer that researches, develops, and builds automotive fluid transfer hoses and lines. It designs products around what installers need and aims to exceed industry quality standards. Signs this line may need replacing include power steering fluid leaks or drips near the hose, a steadily dropping fluid level, and visible damage or wetness along the line. A low fluid level can also cause pump whine. If a leaking return line is the cause, this assembly replaces it.
