Fit for COMPREHENSIVE VEHICLE COVERAGE. Loosen the tire: Remove the valve cap and core and deflate the tire. Dismount the tire: Clamp the tire onto the tire changer, and adjust the valve at 1 o’clock relative to the tire separation head. Insert the tire tool and lift the tire bead onto the mounting head to discount the head. Dismount the sensor: With a screwdriver remove the fastening screw and sensor from the Valve stem, then loosen the nut and remove the valve. Mount sensor and valve: Slide the valve stem through the valve hole of the rim. Tighten the screw-nut with 4.0 Nm with the help of the positioning pin. Assemble the sensor body against the rim and tighten the screw. Mount the tire: Place the tire on the rim, making sure that the valve faces the separation head at an angle of 180 degrees. Mount the tire over the rim. Please check the picture and the part number carefully to make sure that you bought the right part for your car.
