1993 GMC G1500 Service and Repair Manual

This factory service and repair manual for the 1993 GMC G1500 is written so that one book answers for a stripped Vandura cargo van and a trimmed-out Rally STX passenger van alike, in standard or extended length. Under the hood it accounts for three naturally aspirated overhead valve engines, the 4.3L V6, the 5.0L V8 and the 5.7L V8. Tune-up data, clearances and torque sequences are listed per engine, and the driveline, chassis, brake and circuit sections carry their own specifications and diagnostic procedures.
