It takes R-134a. Good luck.
It came from the factory with R12. Due to the high cost of R12, I would have it converted to R134.
It takes R134a, which is the new EPA "standard" freon.
Always use safety glasses and gloves! To remove the A/C compressor you must evacuate system & properly dispose of old R-134A. Then unbolt and remove old compressor. (You should be certified to handle R-134A to charge system)
A 2000 Ford Excursion would be ( 134a ) in the air conditioning system
Its 134a it says it right under the hood.
First you need to find out if the system is a 134a system or not. It is then it recharged through the low port using one of those recharge kits from Walmart or Autozone or wherever. The port only fits on one side. If it is not a 134a system then you will have to have the expensive older freon put in or get a retrofit kit. The later is cheaper. Then refill with 134a. If system has been opened up then the system will have to be hooked to a vacuum pump and then filled with the proper amount of refrigerant and oil. Hope this helps.
Unless your system has been convert to take R-134a you would need 25oz of R-12. If your system has been convert to R-134a you would use 20oz to 21.25oz of R-134a.

The change-over to 134a refrigerant happened in the early 90's - so this one is definitely 134a. See "Related Questions" below for more
