This factory service and repair manual for the 1986 Chevrolet Spectrum documents a naturally aspirated 1.5L SOHC inline-four of 92 cubic inches fitted to a four-door sedan and a two-door hatchback, both in Base specification. Because a single engine and a single equipment level cover the range, the specifications, clearances and torque values given for the engine, driveline and chassis apply to either body, and diagnosis can be followed from the symptom without first establishing which version is on the lift.
