1988 BMW 325is Service and Repair Manual

This factory service and repair manual for the 1988 BMW 325is covers a two-door coupe in a single Base trim with a single engine: 2.5 liters, inline-six, 152 cubic inches, one overhead camshaft, naturally aspirated, gasoline. What that buys the reader is precision. Procedures are written for one layout of accessories and one routing of hoses and looms, so the sequence of steps matches the car on the lift instead of describing a family of cars in general terms.

Known issues on the 1988 325is. Fuel and ignition work is set out with the values needed to judge it: injection system pressures, sensor resistances, ignition timing figures and the test procedures that produce them. The engine mechanical sections cover the cylinder head, camshaft drive and bottom end with torque sequences given in order, and the emissions equipment is documented alongside the systems it monitors. Chassis coverage takes in the brakes, steering and suspension, and the wiring diagrams follow each circuit from its fuse through to its ground.
