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
toRefill capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than –34° F [–36° C ]):
•It may be necessary to increase the coolant concentration
above 50%.
•NEVER increase the coolant concentration above 60%.
•Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
freeze protection at the temperatures in which you drive in the
winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.

Lubricant Specificationsin this chapter. DOT 3 fluid is recommended.
However, if DOT 3 is not available, DOT 4 fluid can be used.
2Ensure the correct automatic transmission fluid is used. MERCONand
MERCONV are not interchangeable. DO NOT MIX MERCONand
MERCONV. Refer to thescheduled maintenance informationto
determine the correct service interval.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick’s normal operating range.
4Add the coolant type originally equipped in your vehicle.
5Rear axles are considered lubricated for life when the vehicle is used for
normal service. See yourscheduled maintenance informationfor
Severe Duty requirements.
6Add 4 oz. (118 ml) of Additive Friction Modifier XL-3 or equivalent
meeting Ford specification EST-M2C118–A for complete refill of
Traction-Lok rear axle.
7Use of synthetic or synthetic blend motor oil is not mandatory. Engine
oil need only meet the requirements of Ford specification
WSS-M2C930-A and the API Certification mark.
