Early models use an A/C Accumulator that is replaceable. All later vehicles have an A/C Accumulator that's a part of the condenser and is not serviceable by itself. Have the refrigerant discharged by a certified air conditioning technician. Disconnect the negative battery cable. The A/C Accumulator is attached to the end of the condenser for early models with a separate A/C Accumulator. Disconnect the tube from each end of the A/C Accumulator. Seal the ends immediately to prevent contamination. Remove the A/C Accumulator from the end of the condenser. Add 40 cc of refrigerant oil to the system, then mount the new A/C Accumulator to the condenser. Replace the O-rings on the tubes with new ones, lubricate them with R-134a-compatible oil and tighten the nuts securely. For later models with an A/C Accumulator as an integral component of the condenser assembly, remove the condenser from the vehicle. Using an Allen wrench, detach the bottom cap and remove the desiccant from the A/C Accumulator with a pair of needle-nose pliers. Use new O-rings and a new bottom cap when installing the new desiccant and tighten the bottom cap to the torque. Be sure to lubricate the O-rings with R-134a-compatible refrigerant oil. Installation is the reverse of removal. Have the system evacuated, charged and leak tested by the shop that discharged it.
