1. Turn the engine off and allow it to cool down. The engine and the coolant will be very hot after running, so it is important to let them cool down before starting to work on the radiator.
2. Park your car on a level surface and engage the parking brake. This will help to prevent your car from rolling while you are working on it.
3. Remove the front bumper cover. There are two screws on the top of the bumper cover, two screws on the bottom of the bumper cover, and one screw on each side of the bumper cover. Use a Phillips head screwdriver to remove the screws. Once the screws are removed, you can pull the bumper cover off by hand.
4. Drain the coolant from the radiator. Place an oil drain pan underneath the radiator drain plug. Use a 12mm wrench to loosen the drain plug and allow the coolant to drain.
5. Disconnect the upper and lower radiator hoses. Use a 10mm wrench to loosen the hose clamps on the upper and lower radiator hoses. Once the hose clamps are loosened, you can pull the hoses off of the radiator.
6. Remove the radiator. Use a 9mm wrench to remove the four bolts that hold the radiator in place. Once the bolts are removed, you can lift the radiator out of the car.
7. Install the new radiator. Place the new radiator in the car and insert the four bolts that hold it in place. Tighten the bolts snugly.
8. Reconnect the upper and lower radiator hoses. Attach the upper and lower radiator hoses to the radiator and tighten the hose clamps.
9. Reinstall the front bumper cover. Line up the bumper cover with the mounting holes and insert the screws. Tighten the screws snugly.
10. Fill the radiator with coolant. Use a funnel to add coolant to the radiator until the radiator is full.
11. Bleed the cooling system. Start the engine and let it run for a few minutes. Turn the heater on and off a few times to help circulate the coolant. Squeeze the upper and lower radiator hoses a few times to help remove any air bubbles. If necessary, add more coolant to the radiator.
12. Test the cooling system. Take your car for a short drive and make sure that the temperature gauge is reading normal. If the temperature gauge is reading high, check the coolant level and make sure that the cooling system is properly bled.
