1991 Chevrolet Sprint Service and Repair Manual

This factory service and repair manual for the 1991 Chevrolet Sprint documents a small car with a wide spread of shapes: two-door convertible, four-door hatchback and two-door hatchback, all sold as Base. Power comes from a 1.0L 61-cubic-inch SOHC inline-three in two forms, turbocharged and naturally aspirated, both burning gasoline. Because the same bay accepts either, service data is written per engine, with induction plumbing, fuel and spark calibration, cooling capacity and lubrication requirements stated where they differ and the shared chassis and body work following.

Known issues on the 1991 Sprint. Owner reporting for this year amounts to two complaints, both entered under engine and engine cooling. Two entries make a note rather than a pattern, but they point at the part of the car this manual treats in most depth: coolant circuit testing, thermostat and radiator service, water pump replacement, fan and belt drive checks, head and gasket procedures with their torque sequences, and the overheating diagnostic charts that separate a flow problem from a combustion one. Turbocharged cars get their own cooling and lubrication requirements alongside.
