• Corrosion on steel tubing in humid or salted-road environments
• Restricted fluid return from a damaged hose assembly
• Noise or poor steering feel caused by fluid loss in the return line

Installation Notes and Tips

Verify routing from the cooler to the pump before installation and compare the original hose shape, fitting style, and length to the replacement part. Inspect adjacent steering components, clamps, and connection points for wear or contamination before filling and bleeding the system. Confirm that the hose seats fully on the ID hose ends and that all connections are clean and secure.
