1999 BMW 323is Service and Repair Manual

This factory service and repair manual for the 1999 BMW 323is documents one coupe, one trim and one engine: a 2.5L DOHC inline-six of 152 cubic inches, naturally aspirated, on gasoline. The specification is plain, but the work often is not, because parts on a car of this vintage have usually been apart before. What the manual restores is certainty, in the form of the factory sequence, the factory torque figure and the factory measured value, in place of the accumulated guesswork of earlier repairs.
