How to add A/C freon 2015 Chevy Tahoe

[@jkwebb02]

You’re supposed to pull a vacuum on the system if you opened the system up. Then add liquid through the high side and top off with vapor through the low side to get 2.02lbs

Good advice!! Although I've never done in that way on any of my cars in the past 30 years with no issues.

I wish I had watched this before buying the freon, I would have gotten a second can. My system only got up to 30 PSI.

Not tire mines take r134a it tells under the hood what freon

Wrong freon. Chevy Tahoe 2015+ uses newer 1234YF not R-134A.

[@marenothecarguy8361]

I made this video 2 years ago and it’s still blowing cold on what you call “ the wrong type of Freon”. Hmmmmm

[@snivesz32]

@@marenothecarguy8361 That’s a good data point, but I just had mine replaced and it called for 2.02lbs (920g) of R1234YF. I don’t know if the two are compatible or if the AC system will operate as efficiently if you use the improper refrigerant.

It is printed R-134a right on the sticker under the hood of his vehicle in the video.

Thanks a bunch.

My tahoe blows cold air when driving , but hot when idling. Not sure what to check

[@marenothecarguy8361]

Sounds like you are low on freon. The increase in engine speed will increase the rotation speed of the a/c compressor, which will result in the cold air even with low freon. But if your freon levels drop more, you won’t get cold air while driving.

How many cans did you add?

[@marenothecarguy8361]

One can was more than enough but more importantly, make sure the amount you add don’t exceed the safe zone on the can gauge.
