Installation Notes and Tips
Confirm end fitting size, fitting type, and hose length before installation. This hose uses 16 mm male O-ring connections at both ends and does not include a bracket or PS switch port. Inspect mating surfaces, O-rings, and adjacent steering components for wear before reassembly. Proper routing is important to avoid contact with heat sources, moving parts, or sharp edges.
Use the vehicle’s service information for torque specifications, fluid type, and bleeding procedure after installation. For Honda Civic steering repairs and other OE-style applications, verify the original hose layout matches the 51-inch configuration before ordering.
