Start by having an air conditioning technician discharge the system and recover the refrigerant. Disconnect the negative battery cable and raise the front of the vehicle on jackstands. Remove the engine cover, air filter and intake hose assembly, and drain the cooling system. Take off the front bumper cover and disconnect the electrical horn connectors. On newer models, remove the under-vehicle splash shield. For 2015 and later models, remove the large multi-purpose bracket to the front of the radiator/condenser by following a series of steps. Disconnect the upper and lower radiator hoses and the electrical connectors for the radiator fan. Remove the engine cooling fan assembly if necessary. Disconnect the A/C lines attached to the condenser and remove the transmission cooler bracket. On older models, compress the plastic tabs on top of the radiator to release it from the support frame. On newer models, remove the Torx screws and tilt the radiator rearward to release it. Lift the radiator and air conditioning condenser assembly from the vehicle and separate the condenser from the radiator.

Make sure the air conditioning condenser is properly attached before seating the radiator into the lower rubber mounts. Fill the cooling system with the proper mixture of antifreeze and water. Start the engine, check for leaks, and allow it to reach normal operating temperature. Recheck the coolant level and add more if necessary.
