The receiver-drier should be replaced whenever the compressor is replaced due to an internal failure. Have the air conditioning system discharged by an automotive air conditioning technician. Disconnect the cable from the negative battery terminal. Caution: On 2015 and later models, if equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable. Remove the air filter housing. Remove the drivebelt. Also, removing the power steering pump and positioning it aside will make access to the compressor easier. Disconnect the compressor clutch electrical connector. Disconnect the refrigerant lines from the compressor. Plug the open fittings to prevent entry of dirt and moisture and discard the O-ring seals. Raise the front of the vehicle and support it securely on jackstands. Remove the front engine splash shield. Unbolt the mounting fasteners and carefully remove the compressor from the vehicle. If a new compressor is being installed, follow the directions with the compressor regarding the draining of excess oil prior to installation. Any replacement compressor used must be designated as compatible with R-134a refrigerant. The clutch may have to be transferred from the original to the new compressor. Installation is the reverse of removal. Replace all O-rings with new ones specifically made for air conditioning system use and compatible with R-134a or R-1234yf refrigerant, as applicable. Lubricate them with refrigerant oil. Have the system evacuated, recharged and leak-tested by the shop that discharged it.
