• Q: How to replace the TPMS Sensor on 2008 Chevrolet Cobalt?

  A: Motor vehicle maintenance begins with vehicle suspension elevation on proper support then wheel and tire extraction for Tire Pressure Indicator Sensor replacement. Ensure you place both the metallic cap and nickel-plated valve on a clean area before tire removal because aluminum and nickel prevent oxidation. Position the bead breaking fixture at a 90 degree angle from the valve stem when preparing to separate the tire bead from the wheel. Insert the tire iron or pry bar slightly clockwise of the sensor body before lifting the tire bead up with it. The tire machine requires operators to rotate the tire/wheel assembly clockwise to move tire beads externally from the rim. This procedure happens again for moving the inner bead to the wheel rim. Proceed to clean the inside surfaces from any remaining tire sealant after the tire removal. To proceed with installation start by removing the tire pressure sensor nut then the sensor itself. Begin by cleaning the grommet area then orient the sensor wheel hole with air passage directed inward and apply the nut until the sensor body maintains parallel position with the wheel's inside surface at 7 N.m (62 lb in. Torque) tightness. When mounting the tire keep the mounting/dismounting head angled opposite to the valve stem by 180 degrees while keeping the bead transition zone 45 degrees counterclockwise to the valve stem position during the gradual clockwise rotation of the tire/wheel combination for internal tire bead placement and then repeat this process for the outer bead. When attaching the tire to the wheel it is crucial to note that off-the-shelf tire pressure sensors come disabled and require manual wheel rotation at speeds above 40 km/h (25 mph) for 10 seconds before they become operational. The installation process ends with sensor learning after vehicle lowering and tire/wheel placement.
