Filling and Bleeding with a Vacuum Cooling System Filler
NOTE:
Always fill the cooling system with the manufacturer's specified coolant. If a non-specified coolant has been used the cooling system must be chemically flushed. Refer to COOLING SYSTEM FLUSHING . Failure to follow these instructions may damage the engine or cooling system.
NOTE:
Engine coolant provides boil protection, corrosion protection, freeze protection, and cooling efficiency to the engine and cooling components. In order to obtain these protections, maintain the engine coolant at the correct concentration and fluid level in the degas bottle.
To maintain the integrity of the coolant and the cooling system:
To maintain the integrity of the coolant and the cooling system:
- Add Motorcraft® Premium Gold Engine Coolant or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Do not mix coolant types.
- Do not add or mix with any other type of engine coolant. Mixing coolants may degrade the coolant's corrosion protection.
- 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 originally equipped with Motorcraft® Premium Gold Engine Coolant since a Ford-approved recycling process is not yet available.
- Install the lower radiator air deflector. For additional information, refer to BODY PANEL SYSTEM - FRONT END BODY PANELS article.
- Install the vacuum cooling system filler and follow the manufacturer's instructions to fill and bleed the cooling system.
- Recommended coolant concentration is 50/50 ethylene glycol to distilled water.
- For extremely cold climates (less than -37°C [-34°F]):
- It may be necessary to increase the coolant concentration above 50%.
- NEVER increase the coolant concentration above 60%.
- Maximum coolant concentration is 60/40 for cold weather areas.
- A coolant concentration of 60% will provide freeze point protection down to -50°C (-58°F).
- Engine coolant concentration above 60% will decrease the overheat protection characteristics of the engine coolant and may damage the engine.
- For extremely hot climates:
- It is still necessary to maintain the coolant concentration above 40%.
- NEVER decrease the coolant concentration below 40%.
- Minimum coolant concentration is 40/60 for warm weather areas.
- A coolant concentration of 40% will provide freeze point protection down to -26°C (-15°F).
- Engine coolant concentration below 40% will decrease the corrosion and freeze protection characteristics of the engine coolant and may damage the engine.
- Vehicles driven year-round in non-extreme climates should use a 50/50 mixture of engine coolant and distilled water for optimum cooling system and engine protection.
