Replace AC Schrader Valve

- Vehicle AC isn't working? Often, when the air conditioner in your car isn't working, a schrader valve is leaking or loose. I'll show you how to replace a schrader valve stem on a vehicle air conditioner system. Over time, the O rings on schrader valves get old and brittle and allow the refrigerant to pass through the schrader valve, service port and service port cap, so the AC system loses refrigerant. As a result, the air conditioner won't blow cold or won't work at all.
These warning cuts are well appreciated.not many DIY doers know the risks of some self repairs. Thank you
Wow!
I never would have thought of modifying a tire repair tool for this.
Great idea!!!
Good morning, Richard. It worked like a charm and got the job done. We're frugal gals and try to use what we have rather than buy yet another tool. We're running out of space to store all of our tools and DIY stuff. :)
@@frugaldiy1 lol......I know what you mean. My tools and workshop (3,200 square feet) have more room than my house.
I have to admit, I'm envious of your workshop. Lucky guy! We feel your pain, Richard. I have 2 bedrooms filled with DIY stuff because the garage is filled up. My living room is now housing the materials for my upcoming siding job--Hardie plank, plywood, insulation, trim and so on. Sister's house (right next door) is the same way. Plus, she built 3 sheds, and those are packed too. It's a crazy DIY life! We likely need to seek professional help related to our addiction to DIY stuff. :)
Same here ☺️ it was great to see it .
@@frugaldiy1 lol.......I hate to admit it but my shop is full also (with other peoples stuff) but that is changing this year as everyone has been given 60 days to get their stuff or I'm taking it to the dump. BTW, Hardie plank is a great product but I have two suggestions, paint all sides with a good quality primer including the edges then install and paint the exterior with a high quality paint. Also, Hardie plank does NOT like to be immersed in water so be sure to follow the manufacturers instructions as to how close you put it to the ground. Other than that Hardie plank lasts almost like the old asbestos shingles (I was a GC and still have those shingles on my own house with fresh paint of course) but that stuff can't be beat for longevity and paint retention without peeling. Good luck and GOD bless!!!
Take a shot every time she says “Schrader valve”
Thank you for the great video. You helped get my 2005 Dodge Ram diesel back to blowing Ice Cold Air! I learned how to make a new tool in the process😅!
I'm glad the video helped you, Jon. ;)
Thanks for sharing, I have a 2007 Corolla s , this winter I had a problem with the heater, every time I tern the heater on the AC compressor goes on! With hot air on the left side and cold on the right.what could be the problem? my mechanic said take the connector for the compressor off in winter and reconnect in summer. Which made me upset with him.
You're welcome. Re your issue, my guess is faulty climate/temperature selector panel inside the car and either a damper that is not operating correctly or some obstruction in the venting.
@@frugaldiy1 thanks ❣️👍🙏 I appreciate your reply I'll look into it this weekend and reply.
Dr nidaa, the damper controls whether hot air or cool/cold air flows through the vents. I'd look at that. I'm not familiar with the climate selection controls in your Corolla, but I do know that the climate control switches can become faulty. I had that happen in a 1991 Camry, so the AC would not turn on. I replaced the switch with one I got from an auto salvage yard, and it worked like a charm. I'm confident you can find and fix the problem yourself. ;)
@@frugaldiy1 yes I'm sure you are right, I remember 2 years ago I tried to install a new cd player and the the technician pulled out the middle switch without removing the middle screw and broke it. I'll check their first thanks.
I disagree with having to replace the Receiver/Dryer if the Scrader valve is leaking, but there is still pressure in the system.... if there is pressure, no moisture can get into the system.
So I got a kit with just the filter? Do I replace the filter or whole recover drier?
And...if there is still pressure in the system you can use a core remover tool that doesn't require an evac. These are a bit more expensive than the $6 valve tool.
Why 650 to replace Schrader valve?
I have to replace the LOW side schrader valve on my Subaru, anybody know if I have to vacuum my lines still? :L
Yes, you need to vacuum out the system whether you replace the high or low schrader valve because if the valves is leaking, air and moisture have been introduced into the AC system.
@@frugaldiy1 Thank you! (:
Of course. Happy to help. You can get a loaner vacuum from a local auto parts store. Make sure the vacuum has enough oil in it before you leave the store. If it doesn't, ask them to add some. If it helps you, here's a link to my video on how to pull a vacuum on an AC system: czcams.com/video/cJYdai_mcZg/video.html
When you replace the schrader valve, or any part on the AC system, you should also replace the receiver/dryer because air and moisture has been introduced into the system. Here's a link to my video on changing the receiver dryer: czcams.com/video/rFZ6HbEFt_c/video.html
Here's a link to my video on charging an AC system: czcams.com/video/7TM2nH_3hqI/video.html
You got this! Happy DIYing!
There is also a tool to remove a schrader valve without having to evacuate the refrigerant in the system (most ac tech have it).
Those schrader valves always have micro leak even new cars.
