Those sometimes stubborn evap schrader valves

Stephen Owner/Technician California Posted   Latest  

Sometimes those evap schraders can be tough to grab and not damage like on this ford. Had to get creative. Used a ¼ inch deep socket of the proper size, with a slightly snug drag, inserted it into the evap quick release connector. Worked out perfect for my evap test.

I don't understand the connection here. Your post indicates a problem with doing something (removing?) a valve, then the message is about adapting to a quick-connect fitting. What is the problem that you needed a solution for?

Hi Martin, I couldn't get the Schrader valve out for the EVAP test. My hose adapter does not have an internal plunger to push the Schrader valve in. Perhaps I should upgrade that. Had to improvise with what I had. It was just a workaround with what I had available. Perhaps I should have added more detail my initial post what I was trying to achieve

Stephen- evap test ports no longer exist on modern/newer cars. The Redline adapter kit is your best friend.

Plus one on the Evap Adapter kit!! The thing works great and fits everything I have had to use it on.

That makes sense. I never considered using an incorrect adapter, and didn't even know such a design is available, so I didn't understand your situation. Even though they are crazy expensive for what they are, they are well worth the money for the time that they save.

Hi Stephen. Did you try using “lefty tighty, righty loosey”? FWIW, evap test port Schrader valve cores are left hand thread, just in case you are not aware or forgot. The only time that I encountered techs unable to remove a metal valve core from the plastic fitting, they forgot that the thread was LH.

My schrader tool couldn't get a bite on the valve, so I didn't want to risk damaging it. But yes, thanks, they are a left hand thread. Easy to forget too!

For sure it's easy to forget Stephen and some may not have even encountered test ports. FWIW I used the Schrader tool for A/C refrigeration.

Little off subject, but what the heck. Reminds me of Left-hand lugs on Mopar and Pontiac up to the early 70's. Modern tire shops are dumbfounded with those.

Yeah, I used to love screwing around with the gas pumpers when they wanted to help me putting tires back on the car.

I guess I have never used a test port for EVAP smoke test. Honestly been a long time since I've had a car that even had one.

Good idea to use a socket.

I do something similar. I either use a length of 5/16" (8mm) steel brake line, or a length of 3/8" (9.5mm) steel brake line. I'll hook on a hose as you do. I'd say it fits 90% of the makes I work on. Edit: Polish the ends of the steel line so you don't rip or tear the O-Ring in the fitting.

That's how I do it as well.
