The accumulator should be replaced whenever the compressor is replaced. The compressor pumps refrigerant through the system and is driven by an engine drivebelt. Have the air conditioning system discharged and recovered. Disconnect the cable from the negative terminal of the battery. Disconnect the compressor clutch electrical connector. Remove the nuts that secure the refrigerant lines at the compressor, remove the lines, then plug the openings on the compressor and the lines. Remove the drivebelt. Disconnect the refrigerant lines from the compressor. Plug the open fittings to prevent entry of dirt and moisture. On 2.4L and 3.7L engines, unbolt the compressor from the mounting brackets and lift it out of the vehicle. On 4.0L models, remove the air filter housing then remove the right engine mount through-bolt. Using an engine hoist, raise the engine enough to access the compressor mounting bolts and secure the engine in this position using a jack, then remove the air conditioning compressor mounting bolts and compressor. 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 refrigerant R-134a. 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 refrigerant R-134a and lubricate them with refrigerant oil. Any refrigerant oil added must also be compatible with refrigerant R-134a. Have the system evacuated, recharged and leak-tested by the shop that discharged it.
