You are absolutely correct I've had that happen when I went to air up a low tire form a nail. I could not get the aluminum cap Off. I almost destroyed the valve stem getting the bad cap off . I Change the rest of them immediately.
Metal caps with gasket are better than plastic ones, but chromed (perhaps nickel plated?) brass are the way to go. YMMV if you live in an area where lots of salt is used in winter
That is great advice, but at that point, you’re basically working for your wheel caps which seems a little bit too much for what they do for your car lol
@@johnd9541 I do agree, but I also think about how TPMS sensors have made people more lazy realistically nobody really checks their pressure anymore until that little light comes up on the dash
I have this very same issue at present with all 4 wheels as I stupidly put 4 metal valve caps on my car approx 6 - 8 months ago that I bought online coz I thought they looked nice and sporty! 🙄 Went to put air in my tires last week and all 4 valves are stuck and won't budge so can't get them off or put any air in tyres either now. Have tried WD40 and pliers on them but still nothing. Any advice or suggestions on how to get them off I would greatly appreciate? Never ever putting metal valves on my car again either when I do finally get them off. Lesson learned big time. 🙄😭
I hate plastic caps. I was recommended to use brass caps and not aluminum. So I purchased a set of brass ones and they've been on my tires for almost 3 years without any issues.
Thank god I watched this before I put similar ones on my Tacoma…idk what I was thinking haha no wonder when I went to try and put these on, it was difficult to thread which was an automatic red flag so I chucked them haha no wonder they were only 2$, I hate being cheap I gotta stop that🤣
Any issue with heavier caps on rubber stems? I recall people having valve stem failures back in the day when the led blink lights were still trendy. I was thinking about getting the TPMS caps for my motorcyle and I am hesitant to do that because of the size/weight and the fact I have rubber stems. One product specifically said only to use on metal stems, but all the other clones dont say that, and most people are saying its not a problem. But if that was the case why would the one brand have the warning.. I think the other companies just dont care and are selling unsafe products and the people that say its fine just dont know any better.
@@TheEnthusiastMechanic Thanks for your input. On the track my bike can go 200mph but on the street, I guess I'll have to take a judgment call between the risk of a slow leak vs the risk of being lazy and not checking my tire pressure. They are about the size of a penny in diameter, mostly plastic but of course have the metal button battery. My stems are straight vertical, id think that's better than the ones angles or 90 degrees. I did find a few horror stories lol, but that's always possible if your looking for it.
I never put on metal caps customers wind up doing this themselves. We’re in the Midwest. We get a lot of salt during the winter season the salt eats away, causing corrosion and the two fuse together, depending on where you live. If you’re in a warm climate, you may not have that issue.
@@TheEnthusiastMechanic some people just don't know how to do it right just like anything else but i been doing that since i was 18 im 49 now so i take car of my cars
copper grease doesn't react well with aluminum, lithium grease is compatible with aluminum and leaves a more durable film, just make sure you don't spray on the inside of the valve , just the threads
The problem only arises if the valve stem is brass and the caps are a different metal. Aluminum caps are by far the worst dissimilar metal you could use. If you use brass metal caps on brass valve stems you should not experience the problem.
I couldn't agree more. These valve caps are one of many automotive trends that are a total inconvenience for everyone.

This customer had this issue on all four wheels. Luckily, I was able to save them without damage. I did replace all of them with plastic.
Galvanic corrosion! Dissimilar metals.
I used some lithium grease on the threads to prevent sticking.
PS don't use copper grease because that doesn't react good with aluminum

Yeah, I missed chemist in HS and learned this the hard way.
Had them on my car I purchased a year ago. Tore my stem off trying to get it off and had the store change the other 3 while was there.
That is why I made the video to help people avoid that happening sucks that happened to you!
If you want to use metal caps, just apply a thin coat of petroleum jelly on the threads. Clean and reapply every 1-2 years.
Use dielectric grease when installing these caps to eliminate/reduce corrosion/binding. Loosen the caps every 2 months to work the threads.
That is great advice, but at that point, you’re basically working for your wheel caps which seems a little bit too much for what they do for your car lol
@@TheEnthusiastMechanic can't really call loosening your caps occasionally as work really. Should be checking air pressure monthly anyways.
@@johnd9541 I do agree, but I also think about how TPMS sensors have made people more lazy realistically nobody really checks their pressure anymore until that little light comes up on the dash
So essentially, if you have metal valve caps but the inner has a plastic thread, it’ll be ok? It’s just the aluminium on brass that’s causing issues?
I’ve got these on all my cars and have never encountered this. I’ll count myself lucky and use silicon grease next time I reinstall them
You are a lucky one.
are valve stem covers okay ? specifically metal ones ? do i need to lubricate the stem covers
The metal ones the plastic doesn’t have any issues

I have a video on how to remove them on my channel

I have this feeling that what if it exploded while im heating the valve 😢 is it safe to really heat it? Just making sure though 😅
I only put enough heat through it to warm it up not enough to make it explode hence the small little torch.
@@TheEnthusiastMechanic alright. Im going to try it now. Im a first time driver thats why im that worried. Thank you for understanding sir! 🙂

Those TPMS reading caps are actually quite small. I have a customer that had some on his vehicle and I was surprised by how tiny they were.

@ViciousXUSMC have you ever thought of converting it to a metallic stem I know you can do that on bikes
I used them, even after using grease. Got stuck! Ended up getting new valves! Never again
I've never had that problem you have to really make sure it is even when you are putting them on

@@TheEnthusiastMechanic I'm in Indianapolis and i have never had a problem i put Vaseline on the inside and on the valve stem
If your adding lube to them of course they won’t stick most people just put them on without lubricant and they seize
@@TheEnthusiastMechanic some people just don't know how to do it right just like anything else but i been doing that since i was 18 im 49 now so i take car of my cars
Truth!
How about wd40 or vaseline on the threads before install them?
WD dries up and I believe Vaseline inflames rubber,if you find a set with a plastic sleeve would be best or not to use them.
Silicon grease (dielectric grease) is safe on rubbers
I bought these bling valve caps from amazon omg they all wont come off what do i do ???😢
Can’t get them off you gotta replace the valve if heat doesn’t work
Yea I made same mistake. Valve stem 🙏 🪦
I went to put air in a metal stem because the car sat 2 years; pushed on the air and snap! It broke clean off. Wheel off, tire off, new stem time. 🥵
Very common now they are going back to brass stems that are rubber lined like the old school ones they are phasing out all metal
Wish I knew this before I did the same mistake smh
It happens not a lot of people are aware of this issue.
My car is 2004 toyota corolla no sensors on my car, also i dont have a mini torch
You’re gonna have to go to the tire shop and replace your valve then
How about grinding it down with my dremmel tool
metal caps looks cool but a PITA to remove.
Put some copper grease on them before you put them on !!!!
That’ll work but it can get messy!
@@TheEnthusiastMechanic if messy you've used too much !
