How To Remove A Stuck Corroded Valve Stem Cap

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.

No worries, down here in the city, they steal them before they have a chance to corrode

LOL, WI reported, not knowing if anyone need to steal those caps. But my point is if the Aluminum caps are hex shape, does it help?

[@roadkill5333]

S & A Auto Repair that's how we get rid of all our junk. Take it to the big apple, put a sign that says :KEEP OFF, on it, put yellow crime scene tape up around it, and my dad dresses like a security guard, grabs a thermos of coffee, and most of it is gone in a hour! BAM!! your cousins daddy ROBERT, is your uncle! It also works great for your excess Christmas garbage!! Just pack a couple of boxes up, and wrap them like Christmas presents!! Put them in the back of your pickup, and drive around with out of state plates on the truck, and WHAMMO!! Santa clause is coming to town!!

[@tomgregoire503]

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.

[@tsilveira5866]

That is very similar to what I did Tom. I used a hacksaw blade and made a cut lengthwise along the valve stem cap. Just as I saw the blade about to go all the way through I used a flat headed screwdriver to pry open the cap and take kit off.

[@anthonyjohn5136]

This saved me money and taught me a ton. A few big car repair services told me they would likely have to break the valve etc., I'm assuming due to the semi-tedious nature of this fix but after seeing your vid I used a Osc Dremel carbide rasp bit and viola! Thanks again! (Side note, I read the fine print on the back of my cap bag and it states to lubricate the cap before placing on and every time it's taken on/off so my error there more so than the cap. )

Man thanks for the great how to do video my job vehicle body man hooked me up and it was a breeze they came right off I'll never put those bogus caps on again, appreciate you brother !

[@ChrisG9978]

Thanks for this video. Super helpful. Ground down my seized stem cap with a Dremel and used a couple of Vise grips, came right off with no damage to the stem. Filled my tire, replaced with a plastic cap. Problem solved.

[@SouthMainAuto]

Excellent!

[@beejj6190]

Did mine today using; matches, pliers, a tiny flat -edged screwdriver, a small, quality serrated steak knife and some cloth tape. Protected the area of the wheel around the valve with the tape. Heated up the valve cap....still wouldn't budge using pliers . Prized part of cap away with the screwdriver... but still mainly stuck fast! Heated again with match flame, got the pliers grabbing the valve and started sawing across the cap with the steak knife. Came apart in one minute! 15 min trial and error in total but job done, only light thread damage but a load of money saved. WD40 the rest of the caps and had a plastic spare! Cheer$ : )

[@DarkRider2k3]

I've had to inform so many people not to use them even if they look good. GREAT tip for removal!!

[@pakak6948]

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.

[@alistairmcclure1930]

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!

[@13jrvernon]

A lighter didn't work but a torch did. 23 dollar one from Walmart worked. Didn't need 2 pliers either to remove.

[@pookatim]

Great tip! Could even be done with a file if no jazzy cut-off wheel is available.

[@zx8401ztv]

Nicely removed, no damage :-D. They do lock up in our damp environment, even without salt. I have seen aluminium caps on disabled peoples path transports. i always advise the owner to replace them with plastic, before it's too late :-(.

[@theliquidsword]

Amazing tip. Just removed 4 with little to no damage on the threads (the 4th tire came out much better than the 1st). Thank you so much for the tip! With any luck, I’ll never need to use it again ;)

[@Yawwee]

Good tidbit of advice, Eric !!!! Now, show a video on how to plug a tire that has a mail or screw hole in it - with rubber plug AND with gooey sticky rope like plugs - on and off the vehicle .... will help those stuck on the road temporarily till they can get to a garage !!!!

[@Yawwee]

@Bobby Brady Yes, Bobby, that's what I keep in my vehicles trunk - a patch kit and cigarette lighter plug air compressor pump. I ask for a video for the wives to know how to do this when they get a nail, screw or hole in the tire .... I live by 3 colleges, and so many times I have had college students (girls mostly) stuck on the side of the road with a flat tire with a screw or nail hole, and no AAA, or car club service, or vehicle insurance coverage for flats. I end up putting a plug in the tire, airing it and charging them a dollar. Then a quick lecture to watch a video on plugging a tire and getting your parents to get you a tire plug kit and air compressor for your safety - along with a good flashlight for night time repairs. I wonder how many of them actually did that ???

[@aaa000777]

I bet that customer was glad he brought the car to you!!! SMART FELLA!!

Awesome I got copper caps and learned my lesson!

[@JPilot2]

G'day, Mr. O! Wow! Great Quick Tip! Once the folks (customers) realize never to use those aluminium caps, ever again... Btw, that was amazing! I've had the same problem, too! Dealing with the corroded metal valve stem caps, on a VW Beetle TDI!! What I did was rather similar, on the flat end piece. Using a Dremel, cut a groove for a flathead screw driver. Then cut carefully down the side of cap. Lightly exposing and only until you see the thread of the valve copper. Then simply keep vice grips in place to allow yourself, using the flat head to break the corrosion bead. Thank you! Great job! Cheers! 😊✌🏼🛠❤️

[@rollingtones1]

if you ever move your shop to Charlotte, North Carolina you would have SO much more free shop time! Almost no problems with rust and corrosion down here compared to THE RUST BELT. You could spend your considerable mechanical skills on many more rewarding and technically challenging problems.

[@Parknest]

We have exactly the same problem over here in the UK. That's a handy little tip for getting them off without trashing the valve stem.

[@johnbuttner5698]

Great tip. I will have to try it if I see that issue. I don't really like TPMS. I used to think that people should know if there tire is flat, then one day I say a person get out of there car at the grocery store and I mentioned to them that their tire was really low and they seemed very surprised until I showed them.

[@jeffryblackmon4846]

Thanks, Eric! Maybe some anti-seize compound would help. All things considered, I will continue to use the rubber caps.

[@nostalgia46]

Jesus, I wish I had known this a year ago. I bought some custom Z71 valve stem covers and just as you said, they essentially welded themselves to my tire stems. Wish I had known this a long time ago and would have just "stuck" with the plastic cap covers. Sheesh!

[@Kobafied]

You can use an aluminum cap if the TPMS valve stem is also aluminum. Galvanic corrosion occurs between dissimilar metals. My Lexus has aluminum stems with aluminum caps and there’s no problem. That said, plastic caps will work with any type of metal, as it does not corrode.

[@phprofYT]

My Jeep Patriot's rotted off after about 6-7 years in UP of Michigan. They just don't corrode as fast and it isn't the galvanic mechanism but they will still turn to oxide dust at some point. Give me brass and rubber caps, please, is what I tell the dealers and tire shops.

[@dafirnz]

@@phprofYT The aluminium Chrysler uses in TPMS sensors is garbage. No other brand corrodes quite the way theirs do.

[@phprofYT]

@dafirnz That makes me feel warm a fuzzy all over. I even bought a Ram to replace it. At least the Ram uses rubber valve stems.

[@cyrex686]

A decent part of my friend's bicycle shop business is removing aluminium seat posts form steel framed bicycles. Drill + adjustable reamer is the solution there.

[@NY411Info]

cyrex686 I didn't think about that. I wonder about the Ford aluminum body against steel how that is gonna pan out. hmm...I guess we will see. I doubt Ford is using any isolators to keep electrolysis from happening . As thin as the aluminum is I don't think it will last long as a anode. I should ask SMA if he has seen any aluminum Ford trucks, and what they look like after becoming a battery in the salt.

[@Arnold7221]

Yeah another good tip, thanks. Got some metal chrome plated valve stem caps, wire brush the threads slightly and a touch of grease both sides all pretty, and very easy to remove. Especially in a snow storm in Idaho, for a tire needing a few Lbs of air.

[@Voidhowler]

Took 4 years but they finally got me

[@colintrout1095]

With some knowledge and patience,you can do a lot. Most shops would just chop that whole valve stem,and charge the customer to remount all 4 tires.love your approach to problems

[@ryanmg92]

It is also worth a note, some vehicles tpms valves now have replaceable valve stems that are a quick and easy swap. Some are still single piece though. Company I work for used to get replacement stems from a company called autogem, don't know if they supply in the states though but I'm sure you can get them from other sources. Handy to know as really they should be replaced with any tyre changes

This is an awesome tip! Eric O. Saved the day without having to spend hundreds on new TPS's 😃

[@macgruff69]

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.

[@Gabriel-unicorn]

Hey Eric, love your channel and your advice. Likely the best channel I have seen. You have a very personal and knowledgable touch. My question: Why do tire repair shops always recommend replacing valve stems when you buy tires. I understand if they are damaged or rubber, but if they are metal and not corroded, then why do they want to replace them? Seems unfair and scamy. Thanks.

Yah Right, where were you and your tip 2 years ago when my rav4 caps corroded on and I twisted the damn stem off.

Great stuff doctor o. Keep them coming sooner or later I'm bound to be a little bit smarter anyway. Another helpful hint for your viewers is if you have a leak in a tire and just can't find it. Wiggle the valve stem just a little bit while spraying some sort of leak detector and you will find that mystery leak. They get old and cracked just like us.

[@throttlebottle5906]

giver some heat pete! meaning "torch it" and squeeze around in a circle, the expands the cap diameter some and pliers help break up the crud. obviously don't cook the whole stem or set there heating it for ages, 5 to 10 seconds bursts is plenty. map gas/propane torch is plenty, I've used lighters before with the flame cranked, sometimes it takes multiple heat cycles and the wind is not your friend. of course cutting them off works 100% of the time, if your in a shop or happen to have cordless/other tools.

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.

[@SmittySmithsonite]

I just ran into this for the first time a few years ago. Never used to see this happen, back when we had normal rubber and brass stems. I've also had quite a few with the valve core hopelessly seized inside when they leave the caps off - have to cut or drill the stem out, unless you want to sit there for 20 minutes holding the shrader valve in (I've done that a few times, if the customer doesn't have the dough for new ones). 21st Century quality automotive parts for ya ... 🤢😡 Great tip! 👍👍

[@NY411Info]

Smitty Smithsonite Yes if you use 2 different metals then it will cause electrolysis and eat away and seize. This is why I only use plastic caps now. However I was a kid once and did the same thing and put chrome caps, of course on brass stems...lol. Dremel got them off. What about tractor tires that have calcium in them that corrode the schraders in.

[@SmittySmithsonite]

@@NY411Info - Oh yeah, seen many a tractor rim completely destroyed, once the tube wears away, or gets pinholes and starts leaking, or leaks out the valve stem. Worst stuff ever, although pound for pound it's an excellent ballast. I had one customer that had some fancy jeweled crown valve caps - every single one had to come off in pieces. What a mess!

[@manuelsalvatierra2940]

It's a charm when there is no cap at all and the the wrong valve stem core is installed in the tpms valve. Them cores get stuck and at times they break and spin but do not come out. When it's a 1 piece tpms, you find yourself in a pickle. It's mostly with the Kias and Nissans
