Known issues on the 1990 G2500. Nothing is recorded against the 1990 G2500 on the federal side, with no recalls and no owner complaints logged with NHTSA. The manual is left to cover the work itself, which on a van this size means engine specifications for the V6 and both gasoline V8s, separate diesel procedures for the 6.2L, torque values through the chassis and driveline, and wiring diagrams paired with diagnostics for the electrical circuits. Cargo and passenger bodies are treated alongside each other rather than in separate books.
