This factory service and repair manual for the 1990 Chevrolet S7 covers one body, one designation and two engines — the gasoline 6.0-liter V8 of 365 cubic inches and the diesel 8.2-liter V8 of 501 — on a cab-forward school bus. A vehicle this narrowly specified makes the book unusually direct to use: there is no trim ladder to sort through and no second body to check against, so the only branch a technician has to take is which engine is in front of them.

Known issues on the 1990 S7. No recalls and no owner complaints stand against the 1990 S7 on the federal record, which makes it clean. Its usefulness is in the procedures: mechanical, fuel and cooling service for each of the two V8 engines with the specifications and torque values proper to each, transmission and axle work, brake system diagnosis and adjustment, steering and suspension figures, and the wiring diagrams and diagnostic charts covering the chassis and body circuits.
