2007 GMC Savana 1500 Service and Repair Manual

This factory service and repair manual for the 2007 GMC Savana 1500 notes a change in the V8: the 5.3L is listed as running flex-fuel or gasoline, while the 4.3L V6 stays a straightforward gasoline engine, both naturally aspirated with overhead valves. Bodies number four, three-door and four-door forms of the standard cargo and standard passenger vans, in Base, LS and LT trim. Fuel system content has to account for the flex-fuel calibration, and it sits with the usual procedures, specifications, torque values, wiring diagrams and diagnostics.

Known issues on the 2007 Savana 1500. The federal record holds three recalls against this model year. A pair of them cover platform-style wheelchair lifts fitted to some of these vans: the lift could move without being commanded and injure the person riding it. The remaining one involves wiring for the optional rear climate system, where an overheated circuit raises the risk of a fire. Thirteen owner complaints are logged, four on the service brakes, three on the air bags and two on the tires. Brake hydraulics, restraint system diagnostics and wheel and tire data are all specified in this manual.
