I did some at work before.Just used the regular VS remover.Just snug them.The Advanced store had a new S10 truck that the rubber seal to the rim was leaking.I fiked that with a rubber from a thread in valve stem.The GM dealer couldnt get one and they only sold the whole unit.Its still working and that was almost a year ago.Rocky

you might see if you can locate one of those metal chrome valve stem caps that has the slotted nub on top for that very purpose. Even if you bought a new set of 4 cheapies in a blister pack it'd sure be cheaper than $25.

Do you realize what I am talking about? Have you recently worked on any rims with TPS? I get the feeling you really haven't. 
If you have, then you'd know exactly what I am talking about as far as torquing them down to prevent stripping it out and damaging the TPS unit or getting messages on your monitor that your tires are low on air all of the time!
FYI- they make a screwdriver tool that properly torques the valve core into the TPS stem -something like 3-5 inch pounds. It has to be torqued to spec. It ain't like the old days when you just tightened the hell out of the core with the core installer screwdriver my friend!

You may not have had them much,but they are getting more and more common.
FWIW,buy the kit that has the torque wrench,valve stem core tool and the service kits.
Bridgeport/Schrader has a complete kit our shop uses.
It is recommended to replace the O-ring,nut,and crush sleeve on most TPMS sensors when servicing tires.
The GM valve stems are available from them and as well from the dealer.
I attended the training seminars and the proper way to dismount a tire wiht a TPMS sensor is remove the valve core,then nut and push the sensor inside the tire and break the tire down.
Of course the guys in the shop skip that and break the bead 180 degrees away from the sensor.
The problem our shop exprienced is Northern climates with salt on the roads can sieze up the valve cores.We have snapped many a sensor that is corroded from winter driving.
It is important to have correct valve stem caps on the sensors.
Fancy chrome caps,or regular plastic ones do not keep moisture out.
Make sure you "test" the valve core before going further.If it is not going to come out,tell the customer heads up that a new sensor may be required.Make sure you get price and availability before proceeding so you wont have a sitting duck on your hands.
Hope this helps.

Check out this page: http://www.schrader-bridgeport.com/index...&Itemid=111Contact your jobber and see if they deal with Schrader. We use their kits and tools in our shop. As noted on the site,never use the regular brass valve cores with the TPMS sensors--always use the nickle plated cores.

Like I said I did a bunch at work.I was just careful not to get zealous reinstalling the stem.Its like rotating tires on them.You have to reset them on the car to shut the light off.We rotated then turn on ign let some air out reair and wait for the horn to beep to recoginise the sensor.Just more work and then people wonder why working on the new stuff costs more.We had one girl with a Pontiac that kept bending rims.She wnet thru 5 new ones and we straightened 4 more.She kept hitting pretty much the same pot hole.Never guess what color hair she had.Rocky

So anytime you rotate the tires on a car with TPS, you have to reset the light? Didn't know that.
So once you rotate the tires, turn on the ignition switch to on position, then you let air out of each one until its about 20 psi. Then re-air them to correct pressure and the horn will beep when the sensors are recognized?

Thats what you have to do on GMs for sure.Takes about 20 minutes total.Have to start charging more than 12 bucks to rotate tires.Rocky

Frankie you need to add a "W" to your explanation,TPS means T-hrottle P-osition S-ensor and TPWS means T-ire P-ressure W-arning S-ensor. Now with terminology out of the way you can get a kit from your local Toyota dealer that has a nut,washer,and seal to repair the "TPWS". Gus

I do this on some of the older stuff I own. One package will cover 4 cars. Here is a tip that can save you some $$$$$. Some of the later model cars ( those with air pressure sensors attached to valve stems, use aluminum valve stems. Do not screw steel caps on these stems ( they come with wimpy looking plastic caps for a reason ). If you switch to steel caps, you will end up with a dissimilar metal corrosion problem right where the metal cap stops on the threaded portion of the valve stem. When you go to check tire pressure, the stem will snap off right at the cap threads due to the corrosion in that area. Only repair is a new sensor / stem. That will be $130 please. Being the dumb arss that I am, took me twice to figure it out:(
