• Fluid loss from cracked, hardened, or rusted steering return components

Installation Notes and Tips

Verify the hose routing and connection style before installation, especially on 2006-2008 Ford Focus models with different return-line layouts. Inspect adjacent fittings, clamps, and mounting points for wear before transferring the new assembly into place. Confirm the vehicle’s steering line position matches the listed application: 2008 Ford Focus, Cooler To Reservoir, and 2006-2007 Ford Focus, Pipe To Reservoir.
