WARNING: To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system
is under pressure. Steam and hot liquid
can come out forcefully when you loosen
the cap slightly. WARNING:
Do not add coolant
further than the MAX mark.
Note: Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the engine cooling or
heating systems. Your vehicle warranty
would not cover this damage.
• DO NOT MIX different colors or types
of coolant in your vehicle. Make sure
you use the correct coolant. Mixing of
engine coolants could harm your
engine ’s cooling system. The use of an
improper coolant could harm engine
and cooling system components and
could void the 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, drain
the cooling system, chemically clean
the system with Motorcraft® Premium
Cooling System Flush, and refill with
prediluted coolant as soon as possible.
Water alone without engine coolant
can cause engine damage from
corrosion, overheating or freezing.
Note: Do not use alcohol, methanol or brine
or any engine coolants mixed with alcohol
or methanol antifreeze coolant. Alcohol and
other liquids can cause engine damage from
overheating or freezing.
Note: Do not add extra inhibitors or
additives to the coolant. These can be
harmful and compromise the corrosion
protection of the engine coolant. Unscrew the cap slowly. Any pressure
could escape as you unscrew the cap.
Add prediluted engine coolant meeting our
specification. See the Capacities and
Specifications chapter of the Owner's
Manual for more information. Whenever
you add coolant, check the coolant level
in the coolant reservoir the next few times
you drive the vehicle. If necessary, add
enough prediluted coolant to bring the
coolant level to the proper level.
Coolant Refill Procedure
Use the following procedure when refilling
the cooling system after it has been
drained or become extremely low.
1. Remove the pressure relief cap from
the coolant reservoir as previously
outlined.
2. Slowly add prediluted coolant to the coolant reservoir until the coolant level
is between the
MIN and MAX marks
on the reservoir.
3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper
radiator hose is warm, which indicates
the thermostat is open and coolant is
flowing through the entire system.
5. Shut the engine off and let it cool.
6. Remove the pressure relief cap from the coolant reservoir as previously
outlined.
7. Add prediluted coolant to the coolant reservoir until the coolant level is
between the
MIN and MAX marks on
the reservoir.
8. Reinstall the pressure relief cap.
9. Check the coolant level in the reservoir
before you drive your vehicle the next
few times with the engine cool.
