1990 Chevrolet B60 Service and Repair Manual
This factory service and repair manual for the 1990 Chevrolet B60 covers the cab forward bus in both the school and non-school versions listed for the year, under the B6P042 designation, with four engines available: the 6.0L OHV and 5.7L naturally aspirated gasoline V8s and the turbocharged and naturally aspirated 8.2L V8 diesels. The two body versions share their running gear, so the difference between them appears in the body and interior sections rather than in the engine, driveline or brake material.
