Making sure to change your 2003 Ford Explorer's antifreeze fluid annually can prevent you from being stranded roadside during inclement winter weather. Being stranded roadside in those conditions could be dangerous for you and your passengers. The Explorer's antifreeze is responsible for allowing the engine to operate in conditions under freezing. Having old antifreeze in your vehicle is almost as bad as having no antifreeze at all.
Place the car ramps in front of the Explorer's front tires. Drive the vehicle onto the ramps, and place it in "Park" for automatic transmissions and in first gear for manual transmissions.
Turn the vehicle off, and allow the engine to cool down for 15 minutes. Locate the bottom of the radiator by laying on your back under the front of the vehicle.
Place the drain pan below the antifreeze drain plug on the bottom of the radiator. Remove the drain plug bolt using the crescent wrench to allow the old fluid to drain into the pan.
Reattach the drain bolt once the antifreeze flow stops. Raise the vehicle's hood, and open the radiator reservoir. Fill the radiator with new antifreeze fluid.
Reattach the reservoir cap, and close the hood. Start the vehicle, and drive off of the ramps.
