Adding Engine Coolant; Recycled Engine Coolant - Ford MUSTANG 2015 Owner's Manual

Adding Engine Coolant

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 warranty may not
cover these damages.
Note: During normal vehicle operation, the
engine coolant may change color from
orange to pink or light red.
As long as the engine coolant is clear and
uncontaminated, this color change does
not indicate that the engine coolant has
degraded, nor does it require that qualified
personnel drain the engine coolant, flush
the system or replace the engine coolant.
Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine's cooling
system. The use of an improper coolant
may harm engine and cooling system
components and may void the warranty.
Use prediluted engine coolant meeting the
Ford specification. See Capacities and
Specifications (page 265).
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 coolant 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.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.

Maintenance
• 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 Ford specification. See Capacities
and Specifications (page 265).
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

Ford Motor Company does not recommend
the use of recycled 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.
