• Noise or steering effort caused by degraded hose condition
• Fluid seepage from worn hose material or aged connections

Installation Notes

Verify routing, length, and end fitting style before installation. This hose uses an ID hose end at one connection and is intended for reservoir-to-pump placement on the listed Mazda 6 applications. Inspect surrounding steering components, clamps, and mounting points for wear before completing the repair.

Quality Assurance

Sunsong manufactures this return hose to exceed original equipment performance standards for the specified application. The corrosion-resistant steel construction and precision fit support a repair that restores the steering fluid path to original-condition operation on compatible Mazda 6 models.
