A 1994 Ford Ranger typically uses R-134a refrigerant in its air conditioning system, and it requires about 2 to 3 pounds of refrigerant. The exact amount can vary based on the specific model and any modifications, so it's best to consult the owner's manual or a service manual for precise specifications. Always ensure proper handling and recovery of refrigerants when servicing the AC system.

Unless the system has been converted to R-134A, vehicles manufactured before 1995 use the R-12 refrigerant.
The 1994 for Ranger pickup truck air conditioning system has a Freon capacity of five pounds. The air conditioning Freon should never be overfilled.
