1986 Chevrolet S10 Blazer Service and Repair Manual
This factory service and repair manual for the 1986 Chevrolet S10 Blazer describes a two-door sport utility in Base, Sport and Tahoe trim, powered by either a 2.5-liter overhead-valve four of 151 cubic inches or a 2.8-liter overhead-valve V6 of 173. Both are naturally aspirated gasoline engines. Because the vehicle comes in one shape, the body, glass, door and interior procedures are written once and apply throughout, and the branching that does exist is confined to the powertrain chapters.

Known issues on the 1986 S10 Blazer. Four recalls sit on the federal record for this year. Three of them concern replacement lamps lacking amber side reflectors, which dims the vehicle's presence to drivers approaching from the side. The fourth involves incorrect tire and wheel information on the certification label, leaving the vehicle out of compliance with the federal tire selection standard. Thirty complaints are recorded, weighted toward seat belts with six, then engine and cooling with four and tires with three, all of them covered by procedures and specifications in this manual.
