    Tire pressure sensor info needed...

    Is it easy to change the sensors from one rim to another? So far two tire shops have turned me down and told me that the dealer needs to do it.

    Those tire shops did you a favor by "sort of" admitting they couldn't do it. Word has not yet reached all tire shops on the proper technique for GM's sensors.

    A short course on dismounting is; pull valve core, remove nut from valve stem, push stem inside the tire, before using a bead-breaker.

    Remounting requires putting both tire beads on the rim before installing the stem (with a new grommet); not a fun job the first time you do it. Install stem mounting nut with 35 lb.-in. torque.

    Be to use the original valve core, or a GM specific replacement; they are nickel plated. And also use the original aluminum stem cap as the aluminum construction forms part of the sensor's antenna.

    If the wheel is installed in a different location on the car, you will have to re-set the RKE system so it can learn the new positions.

    Or, take it to a Cadillac dealer....

    Sorry for the late reply. I've gone into three dealerships and asked about the grommets. They looked at me like I had two heads (I don't). Is it absolutely necessary to use a new grommet? What makes it so hard to put a new grommet on? Do you lube them with rubber lube first? I'm going to have the old tire dismounted, remove the sensor myself, install it on the new rim and have the tire shop mount the new tire. I've gotten three $$ so far $120., $70. and $42. all from dealers. Thanks for the info.
    PS: I did find the grommets, about $2.50 a piece.

    Good news about the grommet; was that from a GM dealer?, or? part number?

    I did some checks with web based GM parts houses and found the sensor is either not available or priced at approx. $52.00 plus shipping. Part #25774006.

    Hope you are ready to rock and roll now....
