Cooling System Draining, Filling and Bleeding: Draining

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never remove the pressure relief cap under any condition while the engine is operating or when the cooling system is hot. To avoid having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pressure relief cap from a hot degas bottle. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When certain all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions may result in damage to the cooling system or engine and/or result in personal injury.
CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly.
CAUTION: All vehicle cooling systems are filled with Motorcraft Premium Gold Engine Coolant or equivalent (yellow color). Always refill the cooling system with the same type of coolant that was drained from the system. Do not mix coolant types.
NOTE: The addition of Cooling System Stop Leak Pellets or equivalent meeting Ford specification WSS-M99B37-B6 darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.
  1. 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.
  2. Remove the splash shields.
