I have an f150, Thanksgiving of 1994, this is a 1995 model, 302, towing,
with a highway gear ratio.
One wheel drive (Just a strange combo).
Question how do I find out if it is R12 or R132.
My search did not turn up anything,
All help welcome.

93 was the last year for R-12

94-up has R-134A

 

Look at the fittings - if they're big quick-connects, it has already been charged with 134, but NOT necessarily converted properly.

 

Another way to tell is that r12 uses york commpressor and 134 uses the smaller round sanden compressor.

 

not true my uncle has a 95 w/ r12 and my work truck is a 94 superduty and it has r 12

 

The York compressor hasn't been used since the early 80s.



Read these captions:

. . Check again. Ford switched Econolines to R-134a in '93 and all F-series/Broncos in '94.

 

Thanks for all responds.

Your pictures indicate 134a. Found the old gages and found.
Old style will not fit. (R12), right size wrong configuration).
I thought it was a normal slow leak,
on inspection, it is a valve leak, I could hear it
when the cap was removed.
Well back to ford. Yes I will replace all.
Thanks

You don't have to "replace all." Just the leaking valve core & the lost refrigerant. If you're quick, you won't even have to pull a vacuum on the system, but don't breathe the escaping refrigerant, or have any sparks/flames nearby. R-134a doesn't burn & hasn't been found to be an environmental hazard, but when it's exposed to spark/flame, it breaks down into hydroflouric acid. It also displaces air, so you can "drown" in it, and the liquid vaporizes around -13°F, so wear protective clothing.

The captions of those compressor diagrams indicate the ORIGINAL refrigerant used in them, but they're capable of working perfectly with either type, provided the rest of the system is compatible.

 

my superduty is a chassis cab and the compressor says r-12 and it has the 7.3 powerstroke diesel

 

Then it was probably the company that installed the body on it that put an R-12 system on it.

 

I was refering to the 150's (which is what he has and also what he was asking) not the 250', 350's or larger.

Same way with airbags, the 150's started using them in 94, but not the 250's.
