1994 BMW 850Ci Service and Repair Manual

This factory service and repair manual for the 1994 BMW 850Ci addresses a car with one engine and one body: a naturally aspirated 5.0L V12 with single overhead camshafts, running on gasoline, in a two-door coupe sold in Base trim. A twelve-cylinder engine doubles much of the routine work across two banks, and the manual gives procedures and specifications for each side rather than covering one and leaving the other to inference. Torque values, clearances, wiring diagrams and diagnostic charts sit with the systems they belong to.

Engines covered

• 5.0L V12 — SOHC, naturally aspirated, gasoline

Body styles covered

• 2-door coupe

Trims covered

• Base

Known issues on the 1994 850Ci. For an engine of this size the coverage that earns its place is mechanical and thermal: cylinder head and timing service with the tightening sequences that go with them, lubrication specifications, and cooling system procedures including pressure testing, thermostat and pump work. Fuel delivery and ignition diagnostics follow, then the transmission and driveline sections. The coupe's chassis material gives suspension, steering and brake specifications, and the body sections carry climate control, lighting and closure hardware with the wiring diagrams needed to trace their circuits.
