Which

I’m trying to do a check on the A/C in my ‘22 Exp. The sticker says R-1234yf, but when I look at all the auto parts stores and enter my year, make and model they all push R-134a. I’m going to use the R-1234yf unless someone here with more knowledge says otherwise.

Go with the sticker hands down. This is a huge legal requirement during assembly.

As a side note as someone who's worked AC, if you suspect a leak, take it to a shop and have them pull a vacuum on the system to determine if you're low and leaking. The system is properly sealed and shouldn't need maintenance unless a seal goes or a line/condenser gets a hole. The home remedies off the shelf can do more damage if not careful, since you can't properly monitor high/low sides and have the system properly balanced.

This will be worth it so much more down the road.

For what its worth, I had AC issues with mine. At first dealer told me it was normal to need a charge after 4 to 5 years so it wouldnt be covered by the Ford ESP. I disagreed but needed my AC. Conversed with the dealer about putting dye in and if the problem returned within a year as I suspected, they would take care of me properly. I had the same issue the following year. The issue was a leak at the rear evap core. Its an entire assembly in the rear panel. Good luck.

If it is worth anything, I fully agree with Hilly.

Enough said, clear and concise.

Thank you Hilly,
