To remove the radiator, start by disconnecting the cable from the negative battery terminal. Then, remove the front bumper cover and the grille support and cover if they are present. On 1.8L models, remove the air intake ducts. Drain the cooling system and save the coolant if it is in good condition. Disconnect the upper and lower radiator hoses, and remove the charge air cooler on 1.4L models. On 1.8L models, disconnect the electrical connector to the air conditioning pressure switch and remove the harness from around the radiator. On 2016 and later models, remove the air deflectors from each side of the radiator. On automatic transaxle models, disconnect the transaxle oil cooler inlet line and remove the transmission cooler line clips. On 2015 and earlier models, remove the hood latch. On 2016 and later models, disconnect the electrical connector from the air conditioning pressure sensor and unclip the condenser. Unclip the cooling fan shroud from the radiator and remove the radiator upper mounting bolts and brackets on 2015 and earlier models. Carefully lift the radiator out. On 2016 and later models, remove the radiator lower bracket mounting bolts and the radiator assembly with the help of an assistant. Slide the lower mounts off the radiator studs, remove the cooling fan assembly, and unclip the charge air cooler. Make sure the rubber radiator insulators remain in place. To install the radiator, inspect the rubber insulators and make sure they are clean and intact. Install the radiator by reversing the removal steps, ensuring that the condenser and fan shroud are properly seated. Fill the cooling system with the correct mixture of antifreeze and water, reconnect the battery, and start the engine to check for leaks. Finally, check and add fluid as needed on automatic transaxle equipped vehicles.
