Use SAE 5W-50 full synthetic or an equivalent SAE 5W-50 full synthetic oil
Must meet Ford specification WSS-M2C931-B.
Do not use;
supplemental engine oil additives,
cleaners or
other engine treatments.
Change your engine oil and filter according to the appropriate schedule listed in the scheduled maintenance information.
ENGINE AND INTERCOOLER COOLANT
Check concentration and level of coolant at the mileage intervals listed in the scheduled maintenance information.
Coolant concentration should be
maintained at 50/50 coolant and water,
equates to a freeze point of -34°F (-36°C)
Coolant concentration testing
Use a hydrometer or antifreeze tester
(i.e. the Rotunda Battery and Antifreeze Tester, 0014–R1060).
The level of coolant should be maintained
at the “cold fill range” level in the coolant reservoir.
If the level falls below,
add coolant per the instructions in the
The Shelby Mustang is factory-filled with a 50/50 coolant and water concentration.
Engine parts could become damaged or not work properly if the concentration of coolant
falls below 40% or
is above 60%
A 50/50 mixture of coolant and water provides the following:
freeze protection down to -34°F (-36°C).
boiling protection up to 265°F (129°C).
protection against rust and other forms of corrosion.
an accurate temperature readout from the engine coolant gauge.
Check the level of the engine coolant in the reservoir.
When the engine is cold
Fill your engine coolant reservoir as outlined in

The coolant should be at the “cold fill range” as listed on the engine coolant reservoir and intercooler coolant reservoir.
To find out how much fluid your vehicle’s cooling system can hold, refer to
Refer to the scheduled maintenance information for service interval schedules.
Be sure to read and understand Precautions when servicing your vehicle in your Owner’s Guide.
If the reservoir is low or empty, add coolant to the reservoir. Refer to Adding coolant
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 the
When adding coolant,
make sure it is a 50/50 mixture of coolant and distilled water.
Add the mixture to the coolant reservoir,
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.
DO NOT
MIX different colors or types of coolant in your vehicle.
MIX recycled coolant and conventional coolant together in the vehicle.
USE stop leak pellets or cooling system sealants/additives
Use alcohol, methanol or brine or any engine coolants mixed with alcohol or methanol antifreeze (coolant)
Refer to Maintenance product specifications and capacities in this chapter.
A large amount of water without coolant may be added, in case of emergency. In this instance, the cooling system must be
drained and
refilled with a 50/50 mixture of coolant and distilled water
as soon as possible.
Water alone (without coolant) can cause engine damage from corrosion, overheating or freezing.
WARNING: 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.
Coolant and intercooler refill procedure
This procedure should be used when refilling the cooling system.
1. Remove the pressure relief cap from the coolant reservoir
2. Slowly add a
50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is at the “cold fill level.”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.
7. Add a
50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is at the “cold fill range.”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 a
50/50 mixture of coolant and distilled water to the coolant reservoir until the coolant level is at the “cold fill range.”After any coolant has been added, check the coolant concentration (refer to the Maintenance and Specifications chapter of your Owner’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.
Brake and clutch (if equipped) systems are supplied from the same reservoir.

The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced. Fluid levels between the MIN and MAX lines are within the normal operating range; there is no need to add fluid.
If the fluid levels are outside of the normal operating range, the performance of the system could be compromised; seek service from your authorized dealer immediately.
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.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 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. Please see the Warranty Guide for complete information.
SVT does not recommend the use of gasoline labeled as
Premium with octane ratings of less than 91.Refer to scheduled maintenance information
for the appropriate intervals for changing the air filter element. When changing the air filter element, use only the Motorcraft air filter element listed. Refer to Motorcraft part numbers .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.
