Start with draining the power steering system and then uninstall the washer bottle. Then, stop the car, remove the coupler bolt from the gear and remove both the power steering pressure and return lines from the gear. For installation, first run the power steering pressure and return line to the gear, securing them tight at 35 Nm (25 ft. lbs.). After that, install the coupler to the gear, snugging it down to 49 Nm (36 ft. lbs.) and reassemble the washer bottle while refilling the power steering system.
