No Job is Too Much for the Right TPMS Valve Stem
Tire pressure monitoring system (TPMS) valve stems have a tough job. They prevent air from forcing their way out of our tires. They are continuously exposed to moisture, dirt and extreme temperatures. They also work in tandem with the TPMS sensors to transmit valuable data about your tire's air pressure. That is why you'll always need the right TPMS valve stem for the job. Here's a small guide to finding the right one for you.
Valve stem sizes are pretty much the same for a wide range of vehicles so there is no need to worry too much about the fit. They can fit just about any rim hole and shut them tight, preventing air from escaping.
Sticking their necks out
Valve stems are usually straight for easy access. This unfortunately makes it vulnerable to being damaged or even torn off by debris on the road. You could try looking at a number of angled valve stems instead. They are relatively less vulnerable to the dangers of the road but may prove a bit of a challenge to manipulate. Be sure to get a valve stem with the right angle to prevent any difficulties in the future.
Valve stems for clamp-in sensors
These sensors have metal valves stems, like aluminum, attached to them. These valve stems are then "clamped" onto the rim of the car with a nut, thus giving its name. They're definitely more expensive but significantly more durable at the same time. Off-roaders should consider getting them, especially since the wheels of their trucks go through all types of punishment.
Valve stems for snap-in sensors
Rubber valve stems are used for snap-in sensors. They are simply pushed into the air hole of the car's rim where they "snap" into place. Rubber valve stems are the cheap and readily available in the market. They're somewhat durable despite its cheap price, making it a good purchase for anybody, especially if you stick to the city roads.
A note about snap-in TPMS valve stems
After changing your tires or replacing the TPMS sensors, you might ask yourself, "Can't I just reuse my snap-in valve after removing them from the rim? They seem to snap into place just fine." Rubber materials weaken and break down with time. Sure, they might fit perfectly with your sensors but not all faults could be seen with the naked eye. Tiny air leaks could occur when reusing rubber valve stems. Everyone would hate to be the guy who comes back to a flat tire. Be sure to get a new rubber valve stem to be safe.
Under Pressure: Replacing TPMS Valve Stems
Tire pressure monitoring system (TPMS) valve stems work in tandem with the TPMS to monitor the pressure of your tires. They also act as the main passageway for air in and out of the tires. A broken or leaking valve steam can quickly result in a flat tire, making their immediate replacement necessary..
Difficulty level: Easy
Tools that you'll need:
- Valve stems
- Flathead screwdriver
- Hydraulic jack
- Crescent wrench or any tool appropriate for the valve stem
- Liquid detergent
Note: This repair job is for snap-in TMPS valve stems.
Step 1:Remove the wheels from your car. In case you're new to automotive maintenance, be sure to jack up the car before doing so.
Step 2:Deflate the tire using any appropriate method. You can depress the Schrader valve of your valve stem, unscrew it from the stem or remove it.
Step 3:Push the tire bead away from the rim to be able to lift them over the TPMS device. Do this carefully to avoid any damage to the TPMS.
Step 4:Detach the TPMS monitor from the valve stem. The methods required to do this may differ so consult with a user manual to determine how to do so.
Step 5:Use the flathead screwdriver to pry the valve stem from the rim. Insert the screw driver in the edges of the valve stem underneath the rim.
Step 6:Grasp the valve stem on the outside of the rim with a set of pliers and slowly push the valve stem in the rim to make it go out the other side. You may have to rock the valve stem back and forth or rotate it a bit to move it.
Step 7:Wash the valve hole with some liquid detergent. Wipe to dry before adding some liquid detergent to lubricate the hole.
Step 8:Install the new valve stem to the rim. Insert the valve stem through the hole. Use a pair of pliers to pull on the valve stem to make sure it is attached securely.
Step 9:Attach the TPMS to the new valve stem according to manufacturer specifications.
Step 10:Move the tire bead over the TPMS and reattach it around the rim.
Step 11:Inflate the tires and check for air leaks.
Step 12:Reattach the wheel to the car.
Step 13:Repeat the process for all the other wheels.
