This particular valve stem is aluminum.It is sealed with a gasket on the inside.If it is leaking,have the gasket.If the valve stem core is leaking,you can have it tightened up or you can get a tool to do it yourself.But be careful,they are fragile.If those 2 aren't the problem,then a new valve stem might need to be replaced.

Dunk this tire so you know where the leak is coming from to start with so you know how to address the repair needed. Many shops will charge you and extra $10 for having to deal with that slime stuff. The fix a flat is not a repair.

SOURCE: 2008 kia sportage with damage to tire valve stem,

Replace the valve stem or have it replaced. There is a special tool to unscrew the valve stem. Remove the wheel and tire from the car and depress the pin in the stem to release the air in the tire. When you have about 90% of the air out of the tire, insert the tool into the stem an turn counterclockwise to remove. After you install the new valve stem, get a ride to a gas station that offers free air and fill the tire up. As long as the tire is still seated to the lip of the rim (check just for your safety but I very highly doubt it unseated from the rim) and fill the tire to the cold psi rating which is stamped on the sidewall of the tire. If you want to check the tire itself for a slow leak prior to doing the steps above, here is what to do. Get a pan or plastic tub that is sightly wider and longer than the tire and rim. Fill the tub with water and set them it in the water (while it is still filled with air) and slowly roll the tire in place and look for small air bubbles to rise. If you see bubbles, there is a leak.

Fuel rail shrader valve leaking how to replace


Yes it does come out. It takes a tire valve stem removal tool to get it out. And believe it or not, a tire valve stem. But before you take it out, just tighten it up. 99.9% of the time, they quit leaking. You can get the tool from any bicycle shop or hard ware store. Some auto parts store sells them. But usually the are for A/C stems. Bigger.

The tire pressure monitors are made in the valve stems. You will have to replace the valve stems then have the codes cleared at the shop. Most tire stores have the tool to reset the tire pressure monitors. It can be a little costly.

07 nissan sentra valve stem leaking


I'm assuming it is a TPMS sensor valve stem? I do not know o any reason the rim would break when replacing it, unless the rim was already cracked around the valve stem hole due to some kind o impact, in which case, the rim should be replaced anyway. As far as fixing it yourself. Unless you can break down the bead seat of the tire and unmount the tire from the rim, you will not be able to replace it yourself. Once the tire is of the rim, the sensor is held in place by a 11mm or a 12mm hex collar. When you remove this collar, the sensor will pull right out from the inside. ANY tire shop should be able to do this for you for very little charge.

My high side port valve is leaking how do i fix it ?


I am guessing you are talking about a/c. If so replaced the small valve inside the tube. It's almost like the valve core in you tire valve stem. Make sure you get the right part! If you use one from a tire, it will leak everything right back out.

How to turn of tire lite that looks like an


Check your tire pressure, and adjust as necessary first.

Next, have you changed anything having to do with the rims/tires/valve stems? The valve stems mounted in your factory rims have a tire pressure monitoring sensor/transmitter mounted on the inside. The valve stem itself is the antenna for the transmitter. If you have had the valve stems, valve cores, or even the valve caps replaced, that can cause a fault in the system.

Also if you used a canned flat repair like 'Fix-A-Flat', that could be clogging the sensor. I don't recommend using fix-a-flat on tires with TPMS, but if you're in a jam, sometimes you have to.

If you had the tires changed, the shop has to be careful when mounting and dismounting the tires. The sensors are easy to damage with tire tools.

In order to reset the TPMS, there is a small button either in the glove compartment, or under the steering wheel. Turn the ignition to the 'on' position without starting the engine. Press and hold the button for approximately three seconds. The light will begin flashing. Release the button and wait at least 7 seconds for the system to relearn the sensors. Then turn the key to the 'off' position. Start the engine, and check that the light turns off after about a second.

If the light still stays on, you need to have the TPMS serviced by a qualified mechanic. This should be either a Toyota dealer, or a shop that uses the appropriate TPMS testing equipment.

Good luck, I hope this helped!
