Q: How to remove and install an air conditioning condenser in a Ford Mustang?
A: Have the air conditioning system discharged by a dealer service department or by an automotive air conditioning shop before proceeding. Raise the front of the vehicle and secure it on jackstands. Remove the lower engine splash shield that is beneath the radiator, attached to the front bumper cover and air deflector, if equipped. On 2011 and later models, remove the radiator support cover fasteners and cover. On 2011 and later models, remove the air cleaner and air inlet tube. Disconnect the refrigerant inlet and outlet lines from the condenser by removing the fasteners for the fittings. Plug or cap all open line fittings to prevent dirt or contamination from entering the system. On 2010 and earlier models, remove the fasteners for the power steering cooler line brackets and move the line aside. On 2011 and later models, remove the upper radiator brackets. Slide the lower part of the condenser off the mounting studs and pull it down, being careful not to damage the flexible air deflectors and seals mounted on the front and rear sides of the condenser. The upper part of the condenser is seated into a bracket and insulator that is mounted to the top part of the radiator. On 2011 and later models, the condenser must be removed from below. If you're going to install a new condenser, pour two ounces of the appropriate refrigerant oil directly into the condenser prior to installing it. When placing the condenser into position, make certain that the condenser is seated into the upper mounts correctly and that the flexible air deflectors and seals are aligned properly. Before reconnecting the refrigerant lines to the condenser, be sure to coat a pair of new O-rings with the appropriate refrigerant oil and install them in the refrigerant line fittings. Tighten the condenser line fittings and mounting fasteners to the torque. Installation is otherwise the reverse of removal. Have the system evacuated, recharged, and leak tested by the shop that discharged it.
