2008 Cadillac DTS TPMS Sensor

You may need to assemble the tire pressure sensor to the valve stem and install the new TORX screw and tighten the TORX screw to 1.3 N.m (11.5 lb in), then apply tire soap to the rubber portion of the valve stem, next using a tire valve stem mounting tool, pull the valve stem through in a direction parallel to the valve hole on the rim, mount the tire to the rim, install the tire/wheel assembly on the vehicle, finally lower the vehicle and learn the tire pressure sensors.

You will need to use the approved tire mounting lubricant. You mustn't use silicon or corrosive base compounds to lubricate the tire bead and the wheel rim. A corrosive type of compound can cause tire or rim deterioration.

You will need to raise the vehicle on a suitable support, remove the tire/wheel assembly, then dismount the tire from the rim, remove the TORX screw from the tire pressure sensor and pull it straight off the tire pressure valve stem, finally remove the tire pressure valve stem by pulling it through the rim.
