Chevrolet B7 problems
The Chevrolet and GMC B series was a series of cowled chassis that were produced by General Motors. Produced across three generations from 1966 to 2003, the model line was a variant of medium-duty trucks marketed under the Chevrolet and GMC nameplates. Initially derived from the medium-duty C/K series, later examples were derived from the GMT530 architecture.
The B-series was constructed as a cowled-chassis design; also known as an incomplete vehicle, all bodywork aft of the firewall was produced by a second-stage manufacturer. While primarily used for school bus applications, General Motors offered the chassis for multiple commercial and specialty uses.
Following 2003 production, the B-series was discontinued as GM concentrated on bus production derived from cutaway cabs. Until its 2009 discontinuation, the medium-duty GMT560 chassis was used for bus applications (only in a cutaway configuration). As of current production, General Motors provides bus chassis for both school bus and commercial bus applications, deriving all production from the light-duty GMT610 (Chevrolet Express/GMC Savana) cutaway van.
