This is a bilingual (English/French) factory air conditioning refrigerant specification caution label affixed under the hood of a Ford truck, uploaded to the gallery of a 1994 Ford Bronco. The label identifies the A/C system refrigerant as R-134a and gives the maximum operating charge weight of 0.94 kg (2 lb. 1 oz.). It specifies the refrigerant oil as Ford Spec. WSH-M1C231-B with a maximum lubricant charge volume of 207 cc (7 fl. oz.), and states the system meets SAE J639. The safety text warns that R-134a fluid is under high pressure, that improper service methods may cause injury, that the system should be serviced by qualified personnel only, and that R-12 refrigerant must never be used (consult the shop manual). The same information is repeated in French under the heading 'Mise en Garde / Climatiseur.' The label carries Ford part number F4TH-19A688-AB and the Ford oval logo with 'Dearborn, Mich.'
