Maintenance and Specifications

Recycled engine coolant

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.
Used engine coolant should be disposed of in an appropriate
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 this chapter.

Severe climates

If you drive in extremely cold (less than –36° C [–34° F]) or extremely
hot climates, it may be necessary to adjust the coolant concentration
levels.
• Extreme cold: increase the coolant concentration above 50%.
NEVER increase the coolant concentration above 60%.
• Extreme hot: it is acceptable to decrease the coolant concentration
below 50%. NEVER decrease the coolant concentration below
40%.
The coolant concentration in severe climates must always be
between 40% and 60%. Coolant concentrations not within the
40%-60% range may cause engine damage.
Refer to the chart on the coolant container to ensure the coolant
concentration in your vehicle will provide adequate protection at the
temperatures in which you drive.

What you should know about fail-safe cooling

If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The "fail-safe" distance depends on ambient temperatures, vehicle load
and terrain.
