Q: How Do I Remove and Replace the Receiver-Drier in an A/C System?A: Have a technician discharge and recover the refrigerant, then remove the condenser for 2004+ models, or the radiator cover for 2003 and earlier. Disconnect fittings from the A/C accumulator top, detach it from the bracket and remove. To install, reverse the process, using new O-rings coated in refrigerant oil. If replacing the A/C accumulator, add 1/3-ounce of oil to the new one, then have the system evacuated, charged and tested by the shop.
