1990 GMC S15 Service and Repair Manual
Regular price
$29.99 USD
Unit price
This factory service and repair manual for the 1990 GMC S15 covers the extended cab and standard cab pickups in Base, High Sierra and Sierra Classic trim, with a 2.8L overhead-valve V6, a 4.3L overhead-valve V6 and a 2.5L overhead-valve inline-four as the engine choices, all naturally aspirated and running on gasoline. Where a repair differs between the four-cylinder and the two V6s, the manual separates the procedures, and it gives specifications, torque values, wiring diagrams and diagnostics for each engine and for the chassis they share.

Known issues on the 1990 S15. Three recalls are on the federal record for the 1990 S15. Two concern replacement lamp assemblies missing the amber side reflectors federal lighting rules require. The third covers cooling fan blades that fatigue and break, with the risk falling on anyone working near a running engine. Three owner complaints are logged, touching engine and engine cooling and the electrical system. The cooling system procedures and specifications, the fan service instructions and torque values, and the wiring diagrams with matching diagnostics all cover that ground.
