Installation Notes and Tips

Confirm the end fittings before installation: 11 mm male captive O-ring on one end and 16 mm swivel O-ring on the other. Verify the vehicle uses the listed switch port configuration and compare the original hose routing, bracket locations, and overall length before removal. Clean the mating surfaces and inspect related steering components for wear or contamination before installing the new line.
