How do you bleed coolant system on 03 Mach 1 mustang 4.6 dohc?

Answer 1

To bleed the coolant system on a 2003 Mach 1 Mustang with a 4.6 DOHC engine, first ensure the engine is cool and remove the radiator cap. Start the engine and let it idle with the heater set to maximum heat; this allows the coolant to circulate. As the engine warms up, check the coolant level and add coolant if necessary, continuing to do so until no air bubbles are visible. Once the engine reaches operating temperature and the thermostat opens, turn off the engine, allow it to cool, then recheck and top off the coolant level before securely replacing the radiator cap.
