How to replace a valve stem

The other day my brother bought this civic from a local dealership. I checked the car in great detail on and off the lot and I discovered that the car had a bad valve stem on the spare tire.

Warning:
Some vehicles are equipped with tire pressure monitoring system (TPMS). The TPMS could be part of the valve stem and could be expensive to replace.

Step 2: Remove the old valve stem.

Once you have gained access to the old valve stem you can remove it by cutting it or pulling it out with pliers.

Step 3: Lubrication/ glue

Next you have to use something will help the valve stem slide in place and when it dries you it should function like glue to prevent air form leaking out. I chose to use dish detergant but any other type of soap would do.

Step 4: Installing the valve stem

The installation process is straight forward. All you need to do is to put the stem trough the hoe and pull it trough. For these step you can use pliers or a valve tool. I use pliers because the tool was hitting the rim and I could not screw it in. I would recommend that you have a metal valve stem extender so you do not run into this problem.

Good instructables !!

I always meant to find out how those vavle stems were installed.

BTW, got a good chuckle when I read about the "mental valve extender"

an easier way to get a bead to seat is take the 4 way valve tool and remove the core with the tool then use a compressor to set the bead, do not exceed max psi for the tire to set it, also you need to lube the bead with soapy water if you break it

I have been meaning to get a "mental valve extender". sounds useful.
We had a handy little tool for this, made it far simpler to do because every now and again you'll wreck the threads on the valve stem, fine if dust caps are plastic but stem extenders just won't go on...
