R - 134a
My 94 Bravada had R-12 but was converted to R-134. I think yours would have R-12 from the factory. Now my a/c is cool, not cold.
Most likely R-134. Just check your fittings. The R-12 fittings won't accept R-134 connection hoses and vice versa. R-12 are screw on schrader type while R-134 are larger.
R134a
With proper retrofit... Yes
R-12 Convert it !! R-134
R-134. All cars/trucks 1994 and after use R-134. 1993 and before use R-12.
r-12
No
It should be R-12 unless it's been retro fitted.
r134a
Ford F150 trucks came with R-12 until 1994. that is when they changed to R 134-A. Most vehicles that came with R-12 have been converted to R 134-A.
