1987 Chevrolet C20 Service and Repair Manual

This factory service and repair manual for the 1987 Chevrolet C20 narrows to a single engine, the 5.7L V8 of 350 cubic inches, overhead-valve, naturally aspirated and gasoline-fueled, in a two-door standard cab pickup offered as Base or Cheyenne. There is no diesel chapter and no second displacement to check against, so the engine sections state one set of clearances, timing figures and torque sequences and stay with them, while the chassis, brake, steering and electrical material covers the two trims without branching partway through.

Known issues on the 1987 C20. Three owner complaints have come in for this year, one each on seat belts, steering and the fuel system: too thin to read as a pattern, but a fair map of where an old truck asks for attention. All three are covered in detail here, with belt anchorage and retractor procedures and their torque values, steering gear adjustment, linkage inspection and alignment specifications, and fuel pump, line and tank service with the test values to measure against, plus the diagnostics that connect a symptom to a cause.
