A 2001 Mercury Sable uses R-134a refrigerant for its air conditioning system. This type of refrigerant became common in vehicles after the phase-out of R-12 due to environmental concerns. If you're servicing the AC system, ensure to use the correct type and follow proper guidelines for handling refrigerants.
R134a
R-12 unless it has been converted over to R-134a.
According to the 2001 Mercury Sable Owner Guide : It came from the factory with a 50 / 50 mix of distilled water and GREEN color antifreeze ( meeting Ford specification ESE-M97B44-A )
Unless it has been converted over to R134 it came with R12. I suggest you convert it to R134a. R12 is very expensive.
