1985 Chevrolet S10 Service and Repair Manual
This factory service and repair manual for the 1985 Chevrolet S10 lists four engines, and the mix shifted this year: a 2.5-liter overhead-valve four of 151 cubic inches now sits alongside the 1.9-liter overhead-cam four of 119, the 2.8-liter V6 of 173 and the 2.2-liter diesel four of 134. Bodies stayed at three, standard cab, extended cab and cab and chassis, and the trim ladder still ran Base, Durango, Sport and Tahoe, so most of the variation a technician meets is in the engine bay rather than the sheet metal.

Known issues on the 1985 S10. Three recalls appear on the federal record for this model year, and all three cover replacement lamp assemblies sold without amber side reflectors, a shortfall that leaves the truck harder for other drivers to pick out from the side. Owners have logged fifteen complaints, weighted toward the power train with five and the engine and cooling system with four, and a pair on seat belts. The transmission, transfer case, cooling system and restraint procedures in this manual carry the specifications and diagnostic steps for exactly those areas.
