To bleed the cooling radiator on a 2003 Explorer Sport Trac, first ensure the engine is cool and the radiator cap is removed. Start the engine and let it run until it reaches operating temperature, then turn the heater on to its highest setting. Carefully add coolant to the radiator as air bubbles escape, and keep the reservoir filled. Once the bubbles stop, replace the radiator cap and check the coolant level in the reservoir.
