1988 BMW M5 Service and Repair Manual

This factory service and repair manual for the 1988 BMW M5 covers a four-door sedan carrying a 3.5L inline-six with double overhead camshafts, naturally aspirated, on gasoline, in a single trim. It is written for exact work: published clearances and torque values, adjustment procedures with the measurements that define them, and wiring diagrams drawn for the car as it was built rather than for a family of related models. Sections follow the vehicle from engine mechanical outward through the driveline, chassis and body.

Known issues on the 1988 M5. For a sedan of this age the manual serves as the missing reference. It carries engine mechanical specifications and torque figures for the 3.5L six, procedures and test values for its fuel, ignition and cooling systems, and the emission control data that goes with them. The gearbox, driveshaft and rear axle have their own specifications, the brakes and suspension their dimensions and geometry settings, and the wiring diagrams make an old harness followable connector by connector rather than by guesswork.
