How much Freon for 2002 Dodge Ram 1500?

how man cans of freeon it take for truck

The label found under the hood when the vehicle was new read 1.63 LBS of R-134A, not Freon.

Two 12 ounce cans of R-134A would be about right.

You can find this information in your owners manual as well as the label under the hood (if it’s still readable after 16 years). As @Nevada_545 pointed out, your truck uses R-134A, not Freon. Make sure you use the correct refrigerant.
