Engine Cooling System: Maintenance Ford Transit VII

Draining

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to «JACKING & LIFTING»(ref-356737) .
2. 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.
3. Place a suitable container below the radiator drain valve. Open the radiator drain valve and allow the coolant to drain. Close the radiator drain valve.

Scheme 7

1. Install the RADIATOR REFILLER and follow the manufacturer's instructions to fill and bleed the cooling system. Recommended coolant concentration is 50/50 ethylene glycol to distilled water. Maximum coolant concentration is 60/40 for cold weather areas. Minimum coolant concentration is 40/60 for warm weather areas.

Filling and Bleeding without RADIATOR REFILLER

Note. 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. To maintain the integrity of the coolant and the cooling system: Vehicle cooling systems are filled with Motorcraft® Specialty Orange Engine Coolant. Mixing coolant types degrades the corrosion protection of the original coolant. Do not mix coolant types. Do not add alcohol, methanol or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles. Used engine coolant should be disposed of in an appropriate manner. Follow the community's regulations and standards for recycling and disposing of automotive fluids.

Note. The addition of stop leak pellets darkens engine coolant.

1. Fill the degas bottle to the max level mark. Recommended coolant concentration is 50/50 ethylene glycol to distilled water. Maximum coolant concentration is 60/40 for cold weather areas. Minimum coolant concentration is 40/60 for warm weather areas.
2. Install the degas bottle pressure relief cap.
3. Start the engine, run and hold at 2,500 RPM for approximately 8 minutes until the thermostat opens, then for another 3 minutes after the thermostat opens.
4. Increase the engine speed briefly to 4,000 RPM and hold for approximately 5 seconds.
5. Return the engine speed to 2,500 RPM and hold for another 3 minutes.
6. Shut the engine OFF and allow to cool.
7. Check the engine for any leaks.
8. Check the coolant level in the degas bottle and fill to the MAX fill line as necessary. Recommended coolant concentration is 50/50 ethylene glycol to distilled water. Maximum coolant concentration is 60/40 for cold weather areas. Minimum coolant concentration is 40/60 for warm weather areas.
