Ford SHELBY GT350 MUSTANG Supplement Manual page 40

Note: For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your dealer.
Ford does not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
Be sure to read and understand
Precautions in your Owner s Manual. If the
coolant has not been checked at the
recommended interval, the engine coolant
reservoir may become low or empty. If the
reservoir is low or empty, add coolant to
the reservoir. See Adding Engine Coolant
in this chapter.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
For more information about engine coolant,
see the Maintenance chapter of the Owner s
Manual.
Adding Engine Coolant
WARNINGS
Do not add coolant when the engine
is hot. Steam and scalding liquids
released from a hot cooling system
can burn you badly. Also, you can be
burned if you spill coolant on hot engine
parts.
Do not put coolant in the windshield
washer fluid container. If sprayed on
the windshield, coolant could make
it difficult to see through the windshield.
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 the cap is loosened
slightly.
Do not add coolant further than the
MAX mark.

Maintenance
Note: Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the engine cooling or
heating systems. This damage would not
be covered under your vehicle s warranty.
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 the
engine coolant has degraded nor does it
require the engine coolant to be drained, the
system to be flushed, or the engine coolant
to be replaced.
• DO NOT MIX different colors or types
of coolant in your vehicle. Make sure
the correct coolant is used. 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.
• In case of emergency, a large amount
of water without engine coolant may
be added in order to reach a vehicle
service location. In this instance, the
cooling system must be drained,
chemically cleaned with Motorcraft®
Premium Cooling System Flush, and
refilled 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 will
escape as you unscrew the cap.
