1998 Chevrolet Express 3500 Service and Repair Manual

This factory service and repair manual for the 1998 Chevrolet Express 3500 adds a sixth body to account for, a five-door standard cargo van, alongside the three-door cargo and passenger vans in standard and extended lengths and the two-door cutaway. Under the hood the choice is four engines wide: the turbocharged 6.5L diesel V8, the 7.4L of 454 cubic inches, the 4.3L V6 and the 5.7L V8. Base and LS are the only trims. Door count matters here, because it changes latch, wiring and seal procedures throughout the body sections.

Known issues on the 1998 Express 3500. Three complaints sit on the record, two of them touching the air bags and one the structure, a thin sample rather than a trend. The manual's value on this van lies elsewhere: supplemental restraint diagnostics and the precautions for disabling the system before body work, sheet metal and door repair procedures for the several shell configurations, engine coverage split between the diesel and the three gasoline units, and the torque values, clearances and wiring diagrams needed to put any of it back together correctly.
