1993 Chevrolet G20 Service and Repair Manual

This factory service and repair manual for the 1993 Chevrolet G20 treats one van in three body forms, extended passenger, standard cargo and extended cargo, sold as Beauville, Chevy and Sportvan. Its engine list runs four deep and mixes fuels: a 4.3L V6 of 262 cubic inches, a 5.0L V8 of 305, a 5.7L V8 of 350 and a 6.2L diesel V8 of 379, all overhead-valve and naturally aspirated. Diagnostics, torque values and wiring diagrams are indexed by system, so a job on one engine does not mean reading past the other three.

Known issues on the 1993 G20. The complaint record for this year runs to 106 reports, and the service brakes account for 44 of them, far ahead of the power train at eleven and the electrical system at nine. A van used at or near its rated load asks a great deal of its brakes, and this manual gives the hydraulic system in detail: pedal and booster checks, master cylinder and wheel cylinder specifications, lining and rotor limits, bleeding sequences, and the diagnostic charts that separate a hydraulic fault from a mechanical one. Transmission and body wiring material follows the same pattern.
