WARNINGTo avoid personal injury, do not unscrew the radiator cap while the engine is operating or 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 personal injury.
CAUTIONThe coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly.
CAUTIONAll vehicles are filled with Motorcraft Premium Gold Engine Coolant. Always fill the cooling system with the same type coolant that is present in the system. Do not mix coolant types.

Note. The addition of Cooling System Stop Leak Pellets darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

Note. Less than 80 percent of the coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty or contaminated coolant requires replacement.

  1. Make sure the engine is cool.
  2. Wrap a thick cloth around the radiator cap. Slowly turn the cap counterclockwise (left) until the pressure begins to release.
  3. Step back while the pressure releases.
  4. When you are sure all the pressure has been released, use the cloth to turn and remove the cap.
  5. Place a suitable container below the radiator draincock. Drain the coolant. Tighten the radiator draincock when finished.
