2025 Ford Mustang Service and Repair Manual

In its second year on the S650 platform, the 2025 Mustang sticks with a turbocharged 2.3L EcoBoost four and the 5.0L Coyote V8, rated at 480 or 486 horsepower in the GT depending on exhaust. EcoBoost, EcoBoost Premium, GT and GT Premium come as coupe or convertible, while the track-focused Dark Horse and Dark Horse Premium are coupe only. Output differences, manual and 10-speed automatic gearboxes, and Dark Horse-specific cooling and chassis parts all change the numbers, so this factory service and repair manual gives 2025 procedures, specifications, torque values, wiring diagrams and diagnostics for both engines, the transmissions, brakes, suspension and electrical architecture.

Known issues on the 2025 Mustang. Six recalls are on federal record for this model year, and owners have filed 17 complaints with NHTSA, mostly on exterior lighting, the electrical system and the engine. The recalls cover a transmission valve body that may have been machined incorrectly, LED headlamp driver modules with a burnt diode, water entering the body control module and killing rear and side lighting, and an EGR valve failure that can cut drive power; two more address wipers stuck on high speed in the cold and fractured engine-bay ground connections. Lighting, body control and transmission diagnostics in this service and repair manual cover these faults.
