When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “cold fill range” as listed on the
engine coolant reservoir.
•Refer to the scheduled maintenance guide for service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein yourOwner’s Guide.
If the engine 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 engine coolant to the reservoir. Refer toAdding
engine coolantin 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.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.

Do not add engine 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 engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
The cooling system in your vehicle is filled with either green-colored
Motorcraft Premium Engine Coolant meeting Ford specification
ESE-M97B44–A or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification WSS-M97B51-A1. To determine your
vehicle’s coolant type (color), check your coolant reservoir.
•Add Motorcraft Premium Engine Coolant (green-colored),
VC-5-A (U.S., Mexico) or CXC-10 (Canada) or Motorcraft
Premium Gold Engine Coolant (yellow-colored), VC-7-B,
depending on the type of coolant originally equipped in your
vehicle.If you are unsure which type of coolant your vehicle requires,
check your coolant reservoir or contact your local dealer.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Speciality Orange Engine Coolant, VC-3 (U.S.,
Mexico) or CXC-209 (Canada), meeting Ford specification
WSS-M97B44-D with the factory-filled coolant.Mixing Motorcraft
Speciality Orange Engine Coolant or any orange-colored extended life
product with your factory filled coolant can result in degraded
corrosion protection.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•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.
•Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.

•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
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.
If you must remove the pressure relief cap or radiator cap (depending
upon engine application), follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Engine coolant refill procedure
The following procedure should be used when refilling the cooling
system after it has been drained or become extremely low.
1. Remove the pressure relief cap from the engine coolant reservoir as
previously outlined.
2. Slowly add a50/50 mixtureof engine coolant and distilled water to
the engine coolant reservoir until the coolant level is at the “cold fill
level” as listed on the reservoir.
3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper radiator hose is warm (this
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 engine coolant reservoir as
previously outlined.
7. Add a50/50 mixtureof engine coolant and distilled water to the
engine coolant reservoir until the coolant level is at the “cold fill range”
as listed 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).

10. If necessary, add a50/50 mixtureof engine coolant and distilled
water to the engine coolant reservoir until the coolant level is at the
“cold fill range” as listed on the reservoir.
After any coolant has been added, check the coolant concentration (refer
toChecking Engine Coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle.
If necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your dealer check the engine cooling system. Your cooling
system may have a leak. Operating an engine with a low level of coolant
can result in engine overheating and possible engine damage.
OCTANE RECOMMENDATIONS
Your vehicle is designed to use
“Premium” unleaded gasoline with
an (R+M)/2 octane rating of 91 or
higher for optimum performance.
The use of gasolines with lower
octane ratings may degrade performance. We do not recommend the use
of gasolines labeled as “Premium” in high altitude areas that are sold
with octane ratings of less than 91.
If your engine knocks under most driving conditions while you are using
fuel with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft part numbersin this chapter.
To reduce the risk of vehicle damage and/or personal burn
injuries do not start your engine with the air cleaner removed
and do not remove it while the engine is running.

Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter
element edges between the air filter
housing and cover. This could cause
filter damage and allow unfiltered
air to enter the engine if not
properly seated.
6. Replace the air filter housing
cover and secure the clamps.

WARRANTY COVERAGE
The Shelby GT500 carries the same New Vehicle Limited Warranty as
other Ford Mustang models. This information is covered in its entirety in
the Ford Motor Company Warranty Guide.
Warranty service for the Shelby GT500 or any SVT vehicle can be
obtained at any Ford or Lincoln Mercury dealer nationwide.
SVT does not recommend modifying or racing SVT vehicles, as they are
designed and built to be driven as delivered from the factory. The Ford
Motor Company Warranty Guide discusses vehicle usage and the
installation of aftermarket parts and their effect on warranty coverage as
follows:
Repairs are not reimbursable under warranty when damage is caused by:
•misusing the vehicle, such as driving over curbs, overloading, racing,
or using the vehicle as a stationary power source.
•altering or modifying the vehicle — including the body, chassis, or
components — after the vehicle leaves Ford’s control.
•non-Ford parts installed after the vehicle leaves Ford’s control,
including, but not limited to, cellular phones, alarm systems and
automatic starting systems.
Please see the Warranty Guide for complete information.
In the event the vehicle is intended for track use, and the loss of
warranty coverage is not of concern, the following powertrain durability
modifications are recommended:
•install transmission oil cooler. Permanent damage to the transmission
will result if the vehicle is subjected to competition conditions without
installation of a transmission oil cooler.
•install rear differential cooler. Permanent damage to the rear
differential will result if the vehicle is subjected to competition
conditions without installation of a differential cooler.
Additionally, perform Multi-Point Inspection and the inspections outlined
in the 120,000 mile Normal Maintenance Schedule outlined in the
Scheduled Maintenance Guide. Refer to the Vehicle Service Manual for
removal and installation procedures. Replace with Genuine Ford and
Motorcraft service parts as needed.
These modifications will not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications will render repairs
non-reimbursable under the New Vehicle Limited Warranty.
