2004 Chevrolet Trailblazer EXT Service and Repair Manual
This factory service and repair manual for the 2004 Chevrolet Trailblazer EXT has the widest specification list in this range: five engines against a single four-door sport utility body and seven trims. They run from a pair of turbocharged twin-cam inline-threes, 1.2L and 1.3L, to the naturally aspirated 4.2L inline-six and the 5.3L and 6.0L overhead-valve V8s. With that much variety, the first step in any engine procedure is identification, and the specifications are indexed so the right set is easy to reach.

Complaints run much higher at 1,357, with 716 against the electrical system, 145 against the fuel system and 70 against exterior lighting — the wiring diagrams, circuit tests and fuel delivery diagnostics here cover all three.
