10P15F A/C Compressor

The 10P15F compressor uses a special paraffin base refrigerant oil YN-9 (E73Z-19557-A) or equivalent refrigerant oil meeting Ford Specification ESH-M2C31-A2. A total oil charge of 240 ml (8 fluid ounces) is used in an A/C system.

CAUTION: It is important that only the specified type and quantity of refrigerant oil be used in the compressor. If there is a surplus of oil in the system, excessive oil will circulate with the refrigerant reducing the cooling capacity of the system. Too little oil will result in poor lubrication of the compressor.

NOTE: When it is necessary to replace a component of the refrigerant system, the procedure must be followed to ensure that the total oil charge in the system is correct after the new part is installed. When the compressor is operated, oil gradually leaves the compressor and is circulated through the system with the refrigerant. Eventually a balanced condition is reached in which a certain amount of oil is retained in the compressor and a certain amount is continually circulated. If a component of the system is removed after the system has been operated, some oil will go with it. To maintain the original total oil charge, it is necessary to compensate for this by adding the lost oil to the new replacement part.

DURING COMPRESSOR REPLACEMENT

NOTE: The suction accumulator/drier and the orifice tube should also be replaced whenever the compressor is replaced.

A new service replacement compressor contains 43 ml (1.4 oz) of refrigerant oil YN-9 (E73Z-19557-A) or equivalent refrigerant oil. Prior to installing the replacement compressor, drain the oil from the removed (old) compressor into a clean calibrated container. Then, drain the oil from the new compressor into another clean calibrated container. If the amount of oil drained from the old compressor is between 3 and 5 ounces, pour the same amount of clean refrigerant oil into the new compressor. If the amount of oil drained from the old compressor is greater than 5 ounces, add 5 ounces of clean oil to the new compressor. If the amount of oil removed is less than 3 ounces, pour 3 ounces of clean oil into the new compressor. Use only the specified compressor oil. This will maintain the system total oil charge within the specified limits.
