Installation Notes and Tips

When installing the Sunsong 3402459 power steering return line hose assembly, ensure the vehicle is safely lifted and the steering system is depressurized. Verify the hose length and fitting sizes match the original equipment. Since this assembly does not include a bracket, secure the hose according to the vehicle’s routing to avoid contact with moving parts or heat sources. The hose ends are designed as ID hose fittings, so confirm compatibility with the existing power steering pump and reservoir connections.
