This factory service and repair manual for the 1987 Chevrolet S7 covers a cab-forward school bus rather than a passenger vehicle, and its specification is single-minded: one 6.0-liter V8 of 365 cubic inches running on gasoline, one body configuration, and one designation, S7T042. Everything in the book therefore applies to the same machine — engine mechanical work, driveline and chassis service, brake and steering specifications, and the wiring diagrams for the circuits a bus body depends on.
