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

  A:

  To replace the tire pressure indicator sensor (Snap In Style) lift the vehicle on an applicable support and remove the tire-wheel assembly. Remove the tire from the rim, with the use of a new Schrader(R) tire pressure monitor (TPM) and new torx screw (in the case of fixing it). Erase the torx screw from the tire pressure sensor and create plain off the tire pressure valve stem, careful not to scope or break the clean coat packaging on the wheels which are of aluminum. Pull off the tire pressure check valve stem, through the rim. During installation, make sure the flat of the valve is aligned with the flats of the snap in the enclosure and keep a note that tpm valves and torx screws are one-time-use only. Mount the tire pressure sensor to the valve stem and slide the new torx screw down locking it in with 1.3 N.m (11.5 lb in). Consult an approved tire mounting lubricant, and do not use the silicon or the corrosive base. Soap up the rubber portion that extends out from the valve stem, and use the tire valve stem mounting tool to "pull" the valve right through again parallel to the valve hole on the rim. Note that Snap Fit tpm sensors are designed to arrive in the off state but will go from this stage when the tire is deflated and the technician will be able to program the vehicle normally. Mount the tire on the rim, tire-wheel assembly is then installed on the vehicle, lower the vehicle, learn the tire pressure sensors.
