1987 GMC S15 Service and Repair Manual
Regular price
$29.99 USD
Unit price
This factory service and repair manual for the 1987 GMC S15 covers five trims — Base, EL, Gypsy, High Sierra and Sierra Classic — on three two-door bodies: an extended cab pickup, a standard cab pickup and a cab and chassis. Two gasoline engines are listed, a 2.8L overhead-valve V6 at 173 cubic inches and a 2.5L overhead-valve inline-four at 151 cubic inches. Trim variation shows up mostly in the wiring, and the diagrams, procedures, specifications, torque values and diagnostics are organized to account for it.

Known issues on the 1987 S15. Three recalls are on the federal record. Two involve replacement lamp assemblies sold for these trucks without the amber side reflectors federal lighting rules require, which leaves the vehicle poorly marked to traffic approaching from the side. The third is mechanical: inner tie rod nuts at the relay rod left under-torqued and uncrimped, able to work loose and let the tie rod separate, taking steering control with it. Four owner complaints are logged, led by engine and engine cooling, with single entries for the electrical system and steering. The steering linkage torque values and lighting diagnostics here address those systems.
INNER TIE ROD TO RELAY ROD NUTS ON STEERING LINKAGE MAY BE IIMPROPERLY TORQUED AND NOT CRIMPED.
Consequence
LOSS OF ONE OR BOTH NUTS COULD LEAD TO INNER TIE RODDISENGAGEMENT, WHICH COULD RESULT IN LOSS OF STE
Remedy
REPLACE STEERING LINKAGE ASSEMBLY.
