BMW 325i, 316i, 318i, 320i, 318is 1994 Workshop Manual

If you’re cracking open a 1994 BMW 3 Series and the only thing between you and a stripped head bolt is a Chilton’s paperback, you’re already losing. I’ve seen it happen. Someone trusts a generic torque spec from a third-party manual and ends up chasing a coolant leak for two days. This 111-page workshop manual—published in 1994 by ANETO-ETAI—is the real deal. It covers the BMW 325i, 316i, 318i, 320i, 318is 1994 Workshop Manual models from the 1991-onward E36 generation. No aftermarket translation, no guesswork. Straight factory-derived data.

BMW 325i, 316i, 318i, 320i, 318is 1994 Workshop Manual: Engine and Transmission

Four-cylinder motors (M40, M42, M43) get their own section starting at page 7. Six-cylinder engines (M50, M50TU for the 325i) run from page 25. Each section breaks down the cylinder head torque sequence, oil pump clearances, and timing chain tension. For the 318is, the M42 engine is documented with its specific VANOS oil line routing. The manual covers the ZF gearbox starting page 41—both the S5-31 and S5-32—and the Getrag 260 from page 46. Automatic transmissions from ZF (page 50) and GM (page 54) are included. Torque converter bolt patterns are factory-specified, not approximated. If you’re swapping a transmission, you want these numbers.

Torque Specs and Brake Procedures

Brake work without factory torque values is a liability. The manual’s section on Frenos (page 73) lists caliper mounting bolt torque in Nm and kilogram-meters. For the 325i front calipers, you’ll see 110 Nm—convert to 81 ft-lb. Rear calipers come in at 35 Nm (26 ft-lb). The parking brake shoe adjustment procedure is step-by-step, not a paragraph of hand-waving. You also get wheel bearing preload specs for both front and rear hubs (pages 67 and 70). No generic “tighten until it feels right.” That’s how bearings fail.

Does This Manual Cover Electrical Diagnostics?

Yes, the Equipo eléctrico section runs from page 81. It includes wiring diagrams for the DME (engine control unit), ABS controller, and central locking. Pinouts are printed, not scanned from a fuzzy copy. You’ll trace a no-start condition by checking the main relay circuit shown on page 85. The manual also covers the alternator and starter replacement sequences—removal steps, bolt sizes, and torque values. One note: the manual is in Spanish, but the diagrams and numbers are universal. If you can read a wiring schematic, you’re fine. For newer models, check the BMW 3 Series 1999-2005 Service Manual.

Why OEM Documentation Beats Aftermarket Reprints

Every time I see a reprinted manual that says “typical” instead of “required,” I want to throw a wrench. This 1994 publication came from ANETO-ETAI, a technical publisher that worked with BMW’s factory data. The table of contents matches the OEM layout: Identificación, Motor 4 cilindros, Motor 6 cilindros, Embrague, each gearbox variant, and suspension. There are 111 pages—no filler. The brake bleeding procedure on page 73 uses the exact sequence from the factory service information system. Aftermarket manuals skip the two-man bleed method and tell you to pump the pedal until it firms up. That’s not a repair; that’s a gamble. Get the original data.

Get the Right Torque Data for Your BMW

Torque specs are the backbone of any engine or drivetrain job. This manual gives you cylinder head bolt torque for the 4-cylinder: 30 Nm + 90° + 90° (page 7). For the six-cylinder 325i, it’s 30 Nm + 90° + 90° + 90° (page 25). Oil pan bolts, flywheel bolts, and even the thermostat housing torque is listed. You also get fluid capacities in liters—for the 325i manual transmission, it takes 1.3 liters of ATF. The ZF automatic holds 3.0 liters. These numbers come from the factory, not from a forum. For earlier models, see the BMW 3-Series 5-Series 1981-1991 Service and Repair Manual. For late 90s, check BMW 3 Series 1992-1998 Service Manual. External resources like Automotive Industry Overview can give you background on Bosch injection systems, but for your specific 318i or 320i, this manual is the only source you need.

Frequently Asked Questions

Is this manual in English?

No, it’s in Spanish. But torque specs and diagrams are universal.

Does it cover the 325i convertible?

The manual covers the 1991-onward 3 Series sedan, coupe, and convertible. The chassis and drivetrain sections apply to all body styles. However, convertible-specific top mechanisms are not detailed in this document. You will need a separate body manual for the hydraulic pump and linkage. The 325i engine and transmission data are fully included.

Can I use this for a 1993 318i?

Yes, the manual covers 316i, 318i, 318is, 320i, 325i from 1991 onward. Your 1993 318i is included.

What torque values are given?

The manual lists torque values both in Nm and the equivalent in kg-m (kilogram-meters). You will need to convert to ft-lb if you are working in imperial units. For example, cylinder head bolts on the 4-cylinder M43 engine are specified at 30 Nm + 90° + 90° (page 7). Brake caliper mounting bolts are listed on page 73. Always use the factory values, not aftermarket guesses. The manual also provides tightening angles for torque-to-yield bolts. That information alone is worth the price.

You’ve got a 1994 BMW sitting in your bay—or your garage—and you need to pull the head, rebuild the brake system, or swap a transmission. A generic manual won’t give you the clutch release bearing preload or the correct fluid type for the Getrag gearbox. This 111-page workshop manual delivers the factory data. Every torque value is original. Every procedure follows the sequence BMW engineers wrote. Don’t trust your job to a third-party reprint. Automotive Industry Overview backs up the importance of OEM documentation. Access the Factory Manual and keep it on your bench.
