10. If necessary, add a50/50 mixtureof coolant and distilled water to
the 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 coolantin theOwner’s Guide).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 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 coolant per month,
have your dealer check the 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.
ENGINE SPARK PLUG INTERVAL
To keep your high performance engine operating at peak performance,
the spark plug service interval is every 45,000 miles (72,000 km).
Reference the Motorcraft Part Numbers chart for the specific spark plug
application.
OCTANE RECOMMENDATIONS
Your vehicle is designed to use
“Premium” unleaded gasoline only,
with an (R+M)/2 octane rating of 91
or higher. SVT recommends using
unleaded gasoline with octane rating
of 93 or higher for optimal performance of this vehicle. Recommended
fuel is an important part of the proper maintenance and optimal
performance of this vehicle. The use of gasoline with octane ratings of 91
or lower can lead to severe mechanical damage to your vehicle, may
degrade vehicle performance and may affect your warranty coverage.
Please see the Warranty Guide for complete information.
SVT does not recommend the use of gasoline labeled asPremiumwith
octane ratings of less than 91.

When changing the air filter element, use only the Motorcraft air filter
element listed. Refer toMotorcraft part numbersin this chapter.
WARNING: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. Loosen the air filter clamp bolt
enough to allow the air filter to slip
off the air filter housing easily.
2. Slip the air filter off from the air
filter housing.
3. Wipe the air filter housing clean
to remove any dirt or debris.
4. Install the new air filter taking
care not to damage the air filter
element. Align tab on closed end of
filter with notch in air filter housing.
5. Tighten the air filter clamp bolt.

1Add the coolant type originally equipped in your vehicle.2Rear axle lubricants do not need to be checked or changed unless a leak is suspected, service is
required or the axle assembly has been submerged in water. The axle lubricant should be changed
any time the rear axle has been submerged in water, using SAE 75W-140 High Performance rear
axle lube, meeting Ford specification WSL-M2C192–A.

automatic transmission fluid. Ensure that the correct MERCONV ATF automatic transmission
fluid is used as indicated on the label on your transmission.4Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface.

WARRANTY COVERAGE
The Shelby GT500 carries the same 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 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.
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 vehicle 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.
•Install Ford Racing brake cooling duct kit. Excessive brake wear will
occur if the vehicle is subjected to competitive conditions without
installation of a brake cooling kit.
Additionally, perform Multi-Point Inspection and the inspections outlined
in the 150,000 mile (240,000 km) Normal Maintenance Schedule of the
scheduled maintenance informationbefore and after track use. Refer
to the Vehicle Service Manual for removal and installation procedures.
Replace with Genuine Ford and Motorcraft service parts as needed.
These modifications may not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications may render repairs
non-reimbursable under the warranty.
