1986 Chevrolet K5 Blazer Service and Repair Manual

This factory service and repair manual for the 1986 Chevrolet K5 Blazer covers the two-door sport utility in Custom and Silverado trim with a three-engine choice: a 5.0L V8 of 305 cubic inches, a 6.2L diesel V8 of 379 and a 5.7L V8 of 350. Trucks of this age are rarely original throughout, so the value of the manual is in the reference figures — what a given clearance, pressure or torque value is supposed to be — rather than in any account of how the vehicle was assembled.
