Draining
| WARNING | Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. 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 degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. |
| 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 | Care must be taken to ensure the accessory drive belt does not become contaminated with engine coolant. |
| CAUTION | Some vehicle cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specifications ESE-M97B44-A (green color). Others are filled with Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always refill the cooling system with the same coolant that was drained from the system. Do not mix coolant types. |
- 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.
- Place a suitable container below the radiator draincock. If equipped, disconnect the coolant return hose at the oil cooler. Close the radiator draincock when finished.
Filling-Bleeding
| 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 Premium Engine Coolant VC-4-A (VC-5 in Oregon, CXC-10 in Canada) 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). Use the same coolant that was drained from the cooling system. Do not mix coolant types. Do not add orange-colored Motorcraft Speciality Orange Engine Coolant VC-2 meeting Ford specification WSS-M97B44-D. Mixing coolants may degrade the coolant's corrosion protection. Do not add alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. Do not mix recycled coolant unless it meets the requirements of Ford specification ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications. Use of such a coolant may harm the engine and cooling system components. |

- Fill the hydraulic cooling fan reservoir to the MAX level. Use Motorcraft MERCON® Multi-Purpose (ATF) Transmission Fluid.
- Apply vacuum for two to three minutes. Remove the vacuum pump
- Start the engine and turn the A/C on MAX. This will run the hydraulic fan. If a whining noise is heard, repeat the procedure.
