Coverage varies by engine and model year. Refer to the chapter list and online content for full details on what's included for your specific vehicle.

For Mustang owners who want to know their car inside and out

The S550 Mustang attracts a particular kind of owner - someone who cares about how the car feels, how it sounds, and how it performs. Whether you daily drive it, track it on weekends, or keep it for weekends only, that enthusiasm is well served by actually understanding what's under the hood.

This manual gives you vehicle-specific procedures for everything from routine maintenance to engine repair and transmission service. For EcoBoost owners, that means understanding the turbo system, intercooler, and the specific service intervals the engine requires. For V8 owners, it means correct torque specs, fluid capacities, and the procedures Ford's own technicians follow.

If you're considering modifications down the line, understanding your stock systems first is the right starting point. The manual is also useful for pre-purchase inspections - knowing how to check a used Mustang against what it should look like can save you from an expensive surprise.

Keep this manual in the garage. When something needs attention, you'll know exactly where to look.
