This is a factory service and repair manual for the 2025 Ford Mustang, which is in its second year on the S650 platform. It gives 2025 procedures, specifications, torque values, wiring diagrams and diagnostics. Coverage includes both engines, the transmissions, brakes, suspension and electrical architecture.
The manual accounts for differences between trims and drivetrains, including output differences, manual and 10-speed automatic gearboxes, and Dark Horse-specific cooling and chassis parts. Its lighting, body control and transmission diagnostics cover faults addressed by recalls on this model year. These include a transmission valve body that may have been machined incorrectly, LED headlamp driver modules with a burnt diode, water entering the body control module, an EGR valve failure that can cut drive power, wipers stuck on high speed in the cold, and fractured engine-bay ground connections.
