Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine's cooling
system. Use prediluted engine coolant
meeting the correct specification. See
Capacities and Specifications (page 351).
The use of an incorrect coolant may harm
the engine or cooling system components
and may not be covered by the vehicle
Warranty.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system with
Motorcraft Premium Cooling System
Flush.
3. Refill with engine coolant as soon as
possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.

Maintenance
Do not use the following as a coolant
substitute:
•
Alcohol.
•
Methanol.
•
Brine.
•
Any engine coolant mixed with alcohol
or methanol antifreeze or coolant.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressure
will escape as you unscrew the cap.
2. Add prediluted engine coolant meeting
the correct specification. See Capacities
and Specifications (page 351).
3. Check the coolant level in the coolant
reservoir the next few times you drive
your vehicle.

4. If necessary, add enough prediluted
engine coolant to bring the coolant level
to the proper level.
Recycled Engine Coolant
We do not recommend the use of recycled
engine coolant as an 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.
Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to have an
authorized dealer increase the coolant
concentration above 50%.
•
A coolant concentration of 60% provides
improved freeze point protection. Engine
coolant concentrations above 60%
decrease the overheat protection
characteristics of the engine coolant and
may cause engine damage.
