Take it to a professional. You have neither the tools nor the knowledge to does this properly. You also have a leak that needs fixing, or you wouldn't need to add refrigerant in the first place. This vehicle may have R12 or may have R134. If it has R12, I would convert it to R134a. R12 is very expensive.
28 ounces of R134a freon...............
R134a
1995 Ford Escort La uses 134a Freon.
R134a
The 1994 Ford Escort LX uses R-134a Freon. This type of refrigerant was used in all Ford Escorts from 1994 through 2002.
how do you chance a serpentine belt on a 1996 ford escort
Where is the computer located in a Ford Escort?
R134a
R-12
Low freon charge and faulty CCRM (Constant Control Relay Module).
Follow the line from the receiver/dryer (On the passenger side of the firewall, looks like a metal bottle with lines running into it) towards the compressor. You can't charge your year of Escort without getting the special fittings from Ford.
I do not know of any freon diagrams. I would not recommend trying to charge your air conditioning sytem; it is very complex and the system is under high pressure. Take your car to a professional.
