2023 Ford Mustang Service and Repair Manual

This factory service and repair manual for the 2023 Ford Mustang is a two-engine book: the naturally aspirated 5.0L DOHC V8 of 307 cubic inches and the turbocharged 2.3L DOHC inline-four of 140 cubic inches, both gasoline. Six trims are covered, EcoBoost, EcoBoost Premium, GT, GT Premium and GT V8 among them, in two-door convertible and two-door coupe bodies. With only the V8 and the turbocharged four to document, the procedures, specifications, torque values, wiring diagrams and diagnostics are split cleanly between the two, and the convertible's body sections are separated from the coupe's.

Known issues on the 2023 Mustang. Two recalls are on federal record for the 2023 car. One is a repeat of an earlier brake fluid level sensor recall, issued for cars whose first repair was done incorrectly and whose sensor may still fail to activate the visual warning. The other applies to cars with automatic transmissions and concerns the transmission itself. NHTSA lists 28 owner complaints for the year. The manual's brake system wiring diagrams and diagnostics and its automatic transmission procedures and specifications cover the two areas the recalls touch.
