This factory service and repair manual for the 2004 Chevrolet Tornado documents a compact pickup of the plainest kind: one engine, one body, one trim. The engine is a 1.8-liter inline-four of 110 cubic inches with a single overhead camshaft, naturally aspirated and fed on gasoline; the body is a two-door standard cab pickup; the trim is Base. There is nothing to identify before work begins, which means the specifications and torque values on any given page are the ones for the truck on the lift.
