Metal valve stem caps-throw them all away

[Elkins45]

Just in case you haven't experienced the joy of removing a metal valve stem cap that has fused itself to the stem through galvanic corrosion, here's your reminder that you need to replace them with plastic ones. The RAV4 I bought last fall had them on three wheels and all three needed vice grips to remove.

dremel is sometimes needed. I've had it where you twist the valve stem in circles and it wont loosen.

But we check pressures monthly, right?

Only when our TPMS batteries are dead.

Just warm it up a little first. Daughter-in-laws old Accord had them. Right front hadn't been checked in who knows how long and was visually very low. Yup needed pliers on that one. First time she came over I was like and the rest that did come off, her grandfather put to 51psi since that was "sidewall" pressure.

Replaced them all with plastic and pressure to door placard all around. Her comment "the car rides so much better".

We get so little rain that my cars never get driven on a wet street. But this is something I've never thought about. I think I'll give them all a dab of anti seize just to be safe.

Wierd. I live in the rust belt with heavy use of salt in the winter and I do not ever experience metal caps seizing on. Never been an issue. I maintain five vehicles.
