WHY IT MATTERS.

S197 launches with a three-valve modular V8 and a body inspired by the first generation. This engine family has its own service procedures, distinct from the later Coyote.

The 2005 car launched with a 4.0L V6 or three-valve 4.6L V8. The 2010 body update preceded the 2011 engine changes. The 2012–13 Boss 302 focused on road-course performance, and the 2013–14 GT500 used a supercharged 5.8L V8.

BUYING & SERVICING.

Match service information to the engine and model year. Inspect clutch and gearbox operation, rear-axle noise, water entry, and modifications. Three-valve and Coyote engines have different procedures and service concerns.

Check the exact vehicle's identification, records, and fitted equipment. Modified engines, transmissions, and brake packages require their own applicable documentation.
