Severe Climates; Recycled Engine Coolant - Ford 2016 EXPEDITION Owner's Manual

3. Refill with engine coolant as soon as
possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
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
303).
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.
If you drive in extremely hot climates:
• It may be necessary to have an
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
Engine coolant concentrations below
40% decrease the freeze and corrosion
protection characteristics of the engine
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
What You Should Know About Fail-
Safe Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to
the red (hot) area and:
