2006 Chevrolet Express 3500 Service and Repair Manual

This factory service and repair manual for the 2006 Chevrolet Express 3500 is a wide book by necessity. A turbocharged 6.6L diesel V8 of 403 cubic inches heads a four-engine lineup that also holds the 6.0L, 5.3L and 4.8L gasoline V8s; seven body configurations include four-door cargo and passenger versions; and three trims, Base, LS and LT, sit on top of all of it. More doors and more engines mean more branching in the wiring diagrams and more separate torque tables to work from.

Known issues on the 2006 Express 3500. Eight recalls are on the federal record. One covers a power steering hose built off specification that can fracture at full lock and lose fluid, taking power assist with it and, on vans with hydraulic brake boosters, some of the braking assist as well. Another covers front and rear belt buckles that will not latch or unlatch. Most of the rest cover aftermarket wheelchair lifts whose sensors may not detect a person on the platform. Eighteen complaints are logged, led by three on the structure.
