71 www.moderntiredealer.com CAUTION: e use of tire sealants is strictly prohibited for vehicles equipped with TPMS. Tire sealants can clog tire pressure sensors. CAUTION: Before installing a tire pressure sensor, ensure you have the correct sensor. As noted, sensors can be easily identified by a black sensor body with a white outline (not solid) oval insignia on the sensor body. Copy the ID number off of the new pressure sensor before installing it into the spare tire. CAUTION: To prevent moisture and contamination from entering the valve stem, the cap used on this valve stem contains an "O" ring seal. Retain the original valve stem cap for reuse. A regular valve stem cap cannot be used as a substitute. Aer inspecting or adjusting the tire pressure, always reinstall the valve stem cap. is will prevent moisture and dirt entry into the valve stem, which could damage the wheel rim sensor. CAUTION: e valve stem used on this vehicle is made from aluminum, and the core is nickel-plated brass. Retain the original valve stem core for reinstallation. Do not substitute a valve stem made of a different material, as the different metals will cause corrosion. CAUTION: Any time a sensor is to be installed in a wheel, a new seal and washer must be installed on the stem to ensure airtight sealing. e nut and valve core should also be replaced (see Figure 1). CAUTION: Do not reuse the sensor- to-wheel grommet. Always use a new grommet when installing a pressure sensor and properly torque the sensor nut. Removal 1) Raise and support the vehicle. Remove the tire and wheel assem- bly from the vehicle. 2) Let the air out of the tire. 3) Remove the sensor nut. NOTE: Before reinstalling an existing tire pressure sensor, replace the valve core, seal and metal washer at the base of the valve stem to ensure proper sealing (see Figure 1). 1) Wipe the area clean around the sensor/valve stem mounting hole in the wheel. NOTE: Make sure the surface of the wheel is not damaged. CAUTION: To avoid damaging the sen- sor antenna strap, hold pressure against the rear of the metal valve stem while the sensor is inserted through the wheel mounting hole and the nut is installed (see Figures 2 and 3). 2) Insert the sensor through the wheel as shown keeping pressure against the rear of the metal valve stem. e poed side of the sensor is to be positioned toward the wheel. Do not aempt to mount the sensor otherwise, or damage may occur. Install the sensor nut (with pressed-in washer) by hand (see Figures 3 and 4). NOTE: Before tightening the sensor nut, push downward on the sensor housing in an aempt to make it flush with the interior contour of the wheel. 3) Using a thin-walled socket, install the sensor nut. While holding the sensor in position, tighten the sensor nut to 71 in.-lbs. (8 N.m). CAUTION: Over-torquing the sensor nut by as lile as 106 in.-lbs. (12 N.m) may result in sensor separation from the valve stem. Under this condition, the sensor may still function; however, the condition should be corrected immediately. 4) Mount the tire on the wheel following the tire changer manufacturer's instruc- tions, paying special attention to the following to avoid damaging the tire pressure sensor: Rotating wheel tire changers Once the wheel is mounted to the changer, position the sensor valve stem approximately 280 degrees from the head of the changer in a clockwise direction Figure 5: Mounting the tire using a rotating wheel machine.
