All to often here in the rust belt we have to deal with corroded metal valve stem caps and especially on TPMS sensors. There are 2 options. We either get them off or you have to replace the stem or TPMS sensor is some cases. -Enjoy!If an SMA Video has helped you out please consider giving using "Patreon" to help support us.

    Thank you for this video. It helped me out. I do not have grinder wheel but I did use an orbit sander with medium grit paper, and it did the trick. Spent about 10 min on each of them. Thanks! ✌🏼

    Ah loom in num… not ah loo minium 😖

  5. Avataaar/Circle Created with python_avatars Tsilveira says:

    I used a hacksaw blade to cut the valve stem cap lengthwise. When I saw that the blade was just starting to go all the way through I stopped and used a scredriver to pry the cap open and then unscrew it from the stem.

  6. Avataaar/Circle Created with python_avatars Sergiy Salamandyk says:

    Dealer installed them for me, because they have misplaced mine. Now I have to use your tip and try to remove them. Thank you.

  8. Avataaar/Circle Created with python_avatars AirborneRanger - Ret says:

    Tried the pliers, tried the lighter, tried the grinder. All good. Thx 🙂

  9. Avataaar/Circle Created with python_avatars Tom Gregoire says:

    Great tip. I used a file instead and it worked same way. Just be careful to occasionally check how deep you’ve gone. I went a bit too far and caught threads on stem.

  10. Avataaar/Circle Created with python_avatars Michael Sharp says:

    Oh okay, so grab a tool that nobody has, fuckin moron

  19. Avataaar/Circle Created with python_avatars IcySpicy says:

    the valve's been stuck corroded by the money

  20. Avataaar/Circle Created with python_avatars Alistair McClure says:

    Thanks for making and posting this. 100% accurate, heat and leverage as recommended by others do NOT work. Grinding away the side of the cap works really quickly and well as demonstrated. Also excellent tip cleaning up the threads after. Great stuff. Unlike the aluminium caps which are an abomination!

  21. Avataaar/Circle Created with python_avatars Ozzy Dotson says:

    You’re pronouncing aluminum incorrectly lol not hating though

  22. Avataaar/Circle Created with python_avatars P Cal says:

    THANK YOU!!!! Worked brilliantly!!!

  23. Avataaar/Circle Created with python_avatars tim uebbing says:

    What is the name of that air compressor tool you are using? I'm knew to the compressor world.

  24. Avataaar/Circle Created with python_avatars Mindburner says:

    nice

  25. Avataaar/Circle Created with python_avatars Brown's Appliance Services says:

    Hell yeah!!!! Worked great for me. Thank you!!!

  26. Avataaar/Circle Created with python_avatars Gavin Creber says:

    Borrowed a Dremel and in 10 minutes problem solved on all 4 tyres…saved me ££ here in the UK. Thank you.

  27. Avataaar/Circle Created with python_avatars Batking28 says:

    Still will never understand blingy dust caps beyond kids with their bikes. cheap black plastic ones anyway, $0.10 a cap, don't corrode, don't add weight to your wheel, better for sealing out water and dirt, no one wants to steal them and most importantly don't get stuck to your valve, imagine getting a flat, going for a quick plug repair to carry on your journey and then not being able to remove the cap to blow up the tyre.

  28. Avataaar/Circle Created with python_avatars Paka K says:

    Great tip! I had to grind both sides of the valve and cut a slot in the top, pried with flat screwdriver – cap broke in pieces – no thread damage.

  29. Avataaar/Circle Created with python_avatars Voidhowler says:

    Took 4 years but they finally got me

  30. Avataaar/Circle Created with python_avatars Terence Jay says:

    Had exactly the same thing. Stuck solid on two of four. Twisted one with pliers, valve stem snapped off, instant flat tyre.

  31. Avataaar/Circle Created with python_avatars John Morales says:

    PB BLASTER PENETRANT – The best product to use to loosen stubborn, seize bolts and fitting !!! Spray, let it soak for 3-5 minutes and then use 2 pliers, 1 to hold the stem and another to twist off the cap.

  32. Avataaar/Circle Created with python_avatars macgruff69 says:

    Thank you. I have been trying for days to get the aluminum caps off with no luck. I should have known better. They locked in place two years ago and I got lucky and got them off. I sprayed them with liquid wrench and put them back on and the would check them every few months. That worked fine until just now when I found two of them a locked on. I used the grinder and got them off. I’m using plain plastic ones from now on.

  33. Avataaar/Circle Created with python_avatars Likha Tale says:

    Thanks u

  34. Avataaar/Circle Created with python_avatars Bikerbro2007 says:

    Great tip!!! I used this method and it worked like a gem. I will never buy aluminum valve stem caps again.

  35. Avataaar/Circle Created with python_avatars Mike Anthony says:

    Exactly what I was thinking, to Dremel it off. This was my verification so thank you.
    Discount Tire would not replace the stem because the tire was like a month over the “needs to be 10 years or newer” policy. Even after purchasing a tire.

  36. Avataaar/Circle Created with python_avatars Raieed Malik says:

    Thank you! This was super helpful taking out rusty after market vavle stem caps on my 18 wrx.

  37. Avataaar/Circle Created with python_avatars Kevin Kennedy says:

    The way you speak is fun.. like Ga-van-ized, Allumninnyum and some others..lol

  38. Avataaar/Circle Created with python_avatars anddtayl1 says:

    Already a subscriber, Googled this issue (Ford + Alum caps) and got this video. That's just how great you are 😉

  39. Avataaar/Circle Created with python_avatars Alexander Jansing says:

    I'm in Utica and did this >.< if you were closer, I would have taken my car over to you!

  40. Avataaar/Circle Created with python_avatars Mark Wheeler says:

    Your valve stem tool looks an awful lot like the one I bought 50 years ago.
