Well my 2023 XL w/3.5 cooling problem erupted the other day while parked in the shade for [3] hours.

I was walking back to my truck on Sunday with my family and heard what I thought was a tire that blew or sounded like a shot gun then a hiss.
Looked around and didn't see any evidence of damage, there was also a police vehicle[Ford Explorer] idling next to my truck and was hoping
that was that vehicle provided they are always running and ridden pretty hard.
I did smell an oil or refrigerant smell , turns out it was a refrigerant line that separated at the steel to flex hose joint under the hood.
Just wanted to share this rare problem and hope this doesn't happen to anyone else out there in the F150 family.
Ironically, my 2021 250 SD has had to be recharged twice while under factory warranty, seems to be holding at this time fortunately.

Back to the F150, odd that the line ruptured while not running and not in heated pressure situation. Granted it was hot outside [105] but my truck
was off for [3] hours and sitting in the shade.
I had just returned from a 700 mile road trip , fortunately it didn't happen then as it would of been an uncomfortable ride through the desert.
I am not upset, as we all know that stuff happens, just suprised.

Curios if this has happened to anyone else out there!

 

Pic?

 

Willing to bet it was low side failure. When system is running you have 1 side of the AC system that can see 250+ psi and the other side would be below 40 psi (lots of variables for these pressure values). Obviously the high side is designed to handle higher pressures. When the system is off both sides equalize and pressure will be dependent on the ambient temp. So ironically the low side will see much higher pressures (especially at 105 F) when the AC is off. For example, R-1234yf at 105 F would be at 135 psi. but only 67 psi at 65 F ambient.

 

What a time of year for that to happen. How soon can dealer take it in. Wonder if they'll have to order the part. I'd hate to be without a perfectly drivable truck for something like this. Even if it has no AC.

 

fortunately it is repaired already.
dropped it off on Monday, completed
on Thursday
The servicing dealership was good
to deal with
thanks!

 

yeah, I’ll find out which line it was
your probably correct as I have been in the HVAC business for a long time and would think the discharge line would be stronger than the line on the suction side.
I see you have your PT chart handy!

 

Do you want to give a plug for the dealer that helped you out so quickly?
