DRIVING YOUR SHELBY GT500 THROUGH WATER
The Ford Shelby GT500 has aerodynamic devices attached to the
underbody designed to help control airflow for superior performance.
Therefore, the driver must be especially careful to avoid driving through
deep or standing water. If driving through deep or standing water is
unavoidable, do not exceed 10 mph (16 km/h). Never drive through
water that is higher than the bottom of the wheel rims. Water may enter
through the air intake due to the vacuum generated in the engine.
Damage caused by the intake of water in the engine is not covered by
the warranty.
WASHING YOUR SHELBY GT500
Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track. Wash
your vehicle by hand, or by using a touchless commercial wash with no
mechanical tracks on the floor. Do not use a power washer or high
pressure wand on the striped surfaces or stripe edges. See theOwner’s
Manualfor information on cleaning products and vehicle care.
To maintain proper cooling and aerodynamics at high speeds, your
vehicle has heat exchangers integrated with the front fascia designed to
maximize performance.
Note:Do not use a power washer or high powered spray nozzle as
damage to the fins could occur.
Note:For heavy accumulation of debris or dirt, clean with a non-metallic
soft bristle car wash brush and warm soapy water as needed.

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 understandPrecautionsin yourOwner’s Manual.
If the coolant has not been checked at the recommended interval, the
engine or intercooler coolant reservoir may become low or empty. If the
reservoir is low or empty, add coolant to the reservoir. SeeAdding
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. For more information about engine coolant,
see theMaintenancechapter of theOwner’s Manual.
Adding Engine Coolant
WARNING: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.
WARNING: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.
WARNING: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.
WARNING:Do not add coolant further than the MAX mark.
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.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specificationsfor more information. 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 prediluted coolant to bring the coolant level to the proper level.
Coolant and Intercooler 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 coolant reservoir as
previously outlined.
2. Slowly add prediluted coolant to the coolant reservoir until the coolant
level is between the MIN and MAX marks 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 coolant reservoir as
previously outlined.

7. Add prediluted coolant to the coolant reservoir until the coolant level
is between the MIN and MAX marks 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 prediluted coolant to the coolant reservoir until the
coolant level is between the MIN and MAX marks on the reservoir.
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 prediluted coolant to bring the coolant 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 45000 miles (72000 kilometers).
See the Motorcraft® Part Numbers chart for the specific spark plug
application.
OCTANE RECOMMENDATIONS
Premium unleaded gasoline with an
(R+M)/2 octane rating of 91 or
higher is required. 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 an octane
rating lower than 91 can lead to severe mechanical damage to your
vehicle, may degrade vehicle performance, and may affect your warranty
coverage.
