Coolant Reservoir: Service and Repair

Degas Bottle









Removal and Installation

NOTICE: Early build vehicle (built before January 19, 2009) cooling systems are filled with Motorcraft(R) Premium Gold Engine Coolant. Late build vehicle (built on or after January 19, 2009) cooling systems are filled with Motorcraft(R) Specialty Green Engine Coolant. Mixing coolant types degrades the corrosion protection of the coolant. Do not mix coolant types. Failure to follow these instructions may result in engine or cooling system damage.

1. WARNING: Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure relief cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may result in serious personal injury.

Release the pressure in the cooling system by slowly turning the pressure relief cap one half turn counterclockwise. When the pressure is released, remove the pressure relief cap.
