What It Helps Address

Installation Notes and Tips

Verify the vehicle’s steering gear-to-cooler routing before ordering. Confirm the end styles match the application: 3/8 in. ID hose on one end and a 16 mm long swivel O-ring fitting on the other. Check bracket locations and hose length against the original line to ensure proper routing and clearance around heat sources and moving components. This part number 3401837 is listed for the specified Ford, Lincoln, and Mercury fitments only.
