Good evening,

If the coolant is full and is overheating then a good chance the thermostat is is bad and needs to be replaced.

NOTICE: Use Motorcraft Orange Antifreeze/Coolant. Do not mix coolant types. Mixing coolant types degrades the coolant corrosion protection and may damage the engine or cooling system.

NOTE: During normal vehicle operation, Motorcraft Orange Antifreeze/Coolant may change color from orange to pink or light red. As long as the engine coolant is clear and uncontaminated, this color change does not indicate the engine coolant has degraded nor does it require the engine coolant to be drained, the system to be flushed, or the engine coolant to be replaced.

Drain the cooling system. Refer to Cooling System Draining, Filling and Bleeding .
Remove the ACL outlet pipe. REFER to Section 303-12, Intake Air System Components - Exploded View .
