Cooling System Draining, Filling And BleedingDraining
1. WARNING: Never remove the pressure relief cap under any conditions while the engine is operating. Failure to follow these instructions can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system, never remove 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 turn and remove the pressure relief cap (still with a cloth). Failure to follow these instructions may 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 and new coolant added.
NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Add new coolant if dirty, rusty or contaminated.
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. Place a suitable container below the radiator draincock.
3. Close the radiator draincock when finished.
Filling
1. CAUTION:
^ Engine coolant provides freeze protection, boil protection, cooling efficiency, and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
^ When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water. To maintain the integrity of the coolant and the cooling system:
^ Add Motorcraft Specialty Orange Engine Coolant VC-2, or equivalent, meeting Ford specification WSS-M97B44-D.
^ Do not add Motorcraft Premium Engine Coolant VC-4-A, or equivalent, meeting Ford specification ESE-M97B44-A (green color), or Motorcraft Premium Gold Engine Coolant VC-7-A, or equivalent, meeting Ford specification WSS-M97B51-A1 (yellow color). Mixing coolant may degrade the coolant's corrosion protection.
^ Do not add alcohol, methanol, or brine, or any engine coolants mixed with alcohol or methanol. These can cause engine damage from overheating or freezing.
^ Do not mix with recycled coolant unless it meets the requirements of Ford specification WSS-M97B44-D. Not all coolant recycling processes meet this Ford specification. Use of such a coolant may harm the engine and cooling system components.
Add the correct engine coolant mixture to the degas bottle and install the pressure relief cap
2. Move the temperature blend selector to the full warm position.
3. Run the engine until it reaches operating temperature.
4. Turn the engine off and allow to cool.
5. WARNING: Never remove the pressure relief cap under any conditions while the engine is operating. Failure to follow these instructions can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system, never remove 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 turn and remove the pressure relief cap (still with a cloth). Failure to follow these instructions may result in personal injury.
Remove the pressure relief cap.
6. Add the correct engine coolant mixture to the degas bottle until the coolant level is between the "COOLANT FILL LEVEL" marks. Install the pressure relief cap.
7. Repeat above steps until the degas bottle level is OK.
Bleeding
1. Select maximum heater temperature and blower motor speed settings. Position control to discharge air at the A/C vents in the instrument panel.
2. Start the engine and allow it to idle. While the engine is idling, feel for hot air at the A/C vents.
3. CAUTION: If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow to cool, and fill the cooling system as described.
Start the engine and allow it to idle until normal operating temperature is reached. Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.
4. Shut the engine off and allow it to cool.
5. Check the engine for coolant leaks.
6. Check the engine coolant level in the degas bottle and fill as necessary.
