To avoid scalding hot steam or coolant from being released from
the engine cooling system, never remove the radiator cap while
the engine is running or hot. Failure to follow this warning may result
in damage to the engine’s cooling system and possible severe personal
injury.
If you must remove the radiator cap, follow these steps to avoid personal
injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Recycled engine coolant
Ford Motor Company recommends the use of recycled engine coolant
produced by Ford-approved processes.
Not all coolant recycling processes produce coolant which meets Ford
specification ESE-M97B44-A, and use of such coolant may harm engine
and cooling system components.
Always dispose of used automotive fluids in a responsible manner.
Follow your community’s regulations and standards for recycling and
disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to Refill capacities in the Capacities and specifications chapter.
Fill your engine coolant reservoir as outlined in Adding engine coolant
in this chapter.
Severe winter climate
If you drive in extremely cold climates (less than –36°C [–34°F]), it may
be necessary to increase the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the coolant concentration in
your vehicle is such that the coolant will not freeze at the temperature
level in which you drive during winter months.
