Q: How to Replace an A/C Condenser on a Subaru Legacy?A: Have an AC technician discharge and recover the refrigerant. Disconnect the battery, remove the air intake duct and radiator brackets. For certain Legacy and Forester models, remove the front grill. Disconnect and cap the refrigerant lines from the condenser. Remove the condenser bolts, lean the radiator back and remove the condenser. Drain the oil from the old condenser and add fresh oil to the new one. Lower the new condenser in place, ensuring lower guides are seated. Reverse the removal process for installation, using new O-rings coated with refrigerant oil. Tighten all bolts and fittings, use specific A/C O-rings, reconnect the battery, and have the system tested by an AC technician.
