Description
A compressor with the wrong pulley or refrigerant connection will not solve an A/C system repair. Four Seasons 78377 is a new 10S20F-pattern compressor supplied with its clutch and intended to replace compatible OEM units with matching manifold arrangements.
The listed unit uses a four-groove serpentine pulley of approximately 108 mm outside diameter, a 12-volt clutch coil, R134a refrigerant and PAG 46 lubricant. The supplier notes that the original-equipment manifold may be required. Mounting hardware and the rest of the A/C system are not included.
