The Manual On How To Take Care of A Shelby Mustang In 3 Clicks



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.


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,

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 Adding engine coolant

  • The coolant should be at the “cold fill range” as listed on the engine coolant reservoir and intercooler coolant reservoir.

  • 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.

Adding coolant

When adding coolant,

  • make sure it is a 50/50 mixture of coolant and distilled water.

  • Add the mixture to the coolant reservoir, when the engine is cool

  • Fill until the appropriate fill level is obtained.

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.


  • 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)

  • Add extra inhibitors or additives to the 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.

Brake/Clutch Fluid 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.

Brake Fluid Fill Levels

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.
