Installation Notes and Tips

Verify the end fittings before installation: one end uses a 3/8 in. ID hose connection and the other uses a 16 mm male O-ring fitting. Confirm the routing style on the vehicle, especially for from-gear and gear-to-cooler configurations. Inspect the steering cooler, hard lines, and connection points for wear or corrosion before installing the replacement hose.

Quality Assurance

This Sunsong hose assembly is manufactured to exceed original equipment performance standards for return-side steering service. High-grade steel tubing with zinc electroplating is used where applicable to improve resistance to corrosion, rust, road salt, water, grime, and humidity.
