ENGINE OVER-REV
Note:Engine torque and maximum rpm are limited until coolant
temperature reaches 170°F (77°C). Warm up is indicated when the redline
indicator band starting point changes from 6250 rpm to 7000 rpm.
Your vehicle is equipped with an over-rev feature to increase the
performance range of your Shelby GT500. When conditions permit,
over-rev is indicated on the tachometer with redline marked at 7000 rpm.
If conditions limit over-rev accessibility, the band is illuminated red from
6250 rpm to 7000 rpm.

5. Locate and carefully remove the
engine oil level dipstick.
6. Wipe the dipstick clean. Insert the
dipstick fully, then remove it again.
•If the oil level is between the
lower and upper holes, the oil level
is acceptable. DO NOT ADD OIL.
•If the oil level is below the lower
hole, add enough oil to raise the
level within the lower and upper
holes.
•
The maximum oil level is between
the upper hash mark and the
upper hole. Oil levels above this
range may cause engine damage.
Some oil must be removed from
the engine by an authorized dealer.
7. Put the dipstick back in and make sure it is fully seated.
ENGINE AND INTERCOOLER COOLANT
The concentration and level of engine coolant should be checked at the
mileage intervals listed in thescheduled maintenance information.
Note:Make sure that the level is between the MIN and MAX marks on
the engine and intercooler coolant reservoirs.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark. If the level is at the MIN mark, add coolant immediately.
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. Refer toAdding
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.

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, 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
and concentration.
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 45,000 miles (72,000 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.

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. For vehicles with a cooler, the axle pump
must be running to perform the service refill.
Fill 1/4-9/16 inch (6-14 millimeters) below bottom of fill hole.3The TREMEC 6060 6-speed manual transmission on your Shelby GT500 uses MERCON® V
automatic transmission fluid. Make sure that the correct MERCON® V 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. For vehicles with a transmission cooler, the engine must be running,
the clutch pedal must be released, and the transmission must be in neutral to perform the service
refill.
