  Q: How to replace the TPMS Sensor (Clamp In Style) on GMC Sierra 3500 Classic?

  A: The process starts by lifting the vehicle onto a proper support type then disconnecting the tire/wheel assembly before proceeding. Position the sensor's both cap and valve onto a clean dry area and make sure to use only aluminum caps and nickel-plated valves to minimize corrosion. Use a bead breaking fixture at a 90-degree angle from the valve stem before inserting a tire iron or pry bar clockwise near the sensor body to pry the tire bead over the mounting/dismounting head. Operate the tire machine to turn the tire/wheel set clockwise so the tire bead crosses to the wheel rim's external side and apply this process again for the internal bead before extracting the tire from the wheel. All remaining tire sealant needs removal from the inner surfaces of tires and wheels. The procedure calls for sensor nut removal and sensor extraction. The installation requires cleaning of the grommet sealing area followed by sensor insertion into the wheel hole with the air passage directed toward the outside of the wheel while installing the sensor nut while positioning the sensor body parallel to the inside wheel surface then tightening it to 7 N.m (62 lb in). To resume tire installation start by positioning the mounting/dismounting head at right angles to the tire valve stem with both bead transitions oriented 45 degrees counterclockwise to the valve stem. The clockwise movement of the tire/wheel assembly directs the tire bead into the wheel rim followed by repeating the process for the outer bead. You must spin the tire/wheel combination faster than 20 mph or 32 km/h above the ground for at least ten seconds to operate the service replacement tire pressure sensor properly before reinstalling your vehicle's tire/wheel assembly.
