Tires/2008 Nissan Pathfinder Valve stem leak


My valve stem is leaking air and I have to add air every other day.  Is this something that I can replace myself or do I have to pay $250 to have it done at the car dealer?  It has a sensor in it - it is not just a regular valve stem.


For practical purposes, this is something that requires specialized equipment.

And, no, it might not cost $250, especially if the leak is only on the valve portion and not the sensor portion.  Use a regular tire shop, not the dealer.  They will be less expensive.

I have over 30 years experience in the design, manufacturing, and testing of tires. I have served as the technical advisor to the "800" number. I have authored or co-authored many publications - usually without credit. I can answer almost any technical question, but please don`t ask me to compare brands. I probably have prejudices because of my work experience.
