Dodge Journey: Assembly

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Failure to properly adjust the refrigerant oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.

NOTE: When replacing multiple A/C system components, refer to the REFRIGERANT OIL CAPACITIES to determine how much oil should be added to the refrigerant system. NOTE: If only the rear A/C evaporator is being replaced, add 30 milliliters (1 fluid ounce) of refrigerant oil to the refrigerant system. Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.

NOTE: Replacement of the refrigerant line O-ring seals is required anytime a refrigerant line or expansion valve is disconnected. Failure to replace the rubber O-ring seals could result in a refrigerant system leak.
