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.

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.
