Nissan 200SX 1980 Service Manual – OEM Factory Specs

Description

If you’ve ever fought an aftermarket reprint that skips the torque spec for a head bolt or gives you a wiring diagram that’s close but not correct, you know why I’m not gentle about this. 28 years in the shop have taught me one thing: factory documentation is the only thing that keeps a comeback from happening. This Nissan 200SX 1980 Service Manual is the genuine OEM print from Nissan Motor Co., Ltd., 572 pages of the same material the dealer techs used. No third-party edits, no scanning errors that turn 45 ft-lb into 35 ft-lb.

I’ve pulled plenty of these manual PDFs off the shelf at my shop in San Antonio. The first thing I check is the Quick Reference Index on page 2. Nineteen sections, each with its own contents list and page numbers for the specific topic you need. That index alone saves you from flipping through 500 pages to find the clutch adjustment procedure. Page 3 shows you How to Use This Manual—it tells you that measurements are given in SI units with metric and yard-pound equivalents, and it lists where to get the special service tools. Kent Moore Corporation. That’s the kind of detail a real factory manual gives you.

Nissan 200SX 1980 Service Manual: Engine Mechanical Chapter Detail

Section E–ENGINE MECHANICAL covers the SJ20 series engine. You’ll find cylinder head torque sequences, valve clearance specs, and the exact procedure for piston ring installation. The manual doesn’t assume you know where the timing marks are—it shows you. And if you’re doing an engine removal, Section EM (ENGINE REMOVAL INSTALLATION) gives you the lifting points and the tie-down method from the GENERAL INFORMATION section. All factory validated.

Engine Fuel and Exhaust Systems Coverage

The FUEL section (iF) and ENGINE CONTROL FUEL EXHAUST SYSTEMS (F) cover the carburetor setup and the emissions control components. If you’re working on a 1980 200SX that still has the original Hitachi carb, you need the float level adjustment on page [DATA NEEDED]. The manual also includes the emission control system (E) with vacuum routing diagrams. Aftermarket manuals often omit those diagrams because they’re hard to scan. This one has them clear.

What Torque Values Are Listed?

Every section that involves fasteners includes a tightening torque table. The TIGHTENING TORQUE OF STANDARD BOLT table in GENERAL INFORMATION gives you baseline values for common bolt grades. Then each section—like ENGINE LUBRICATION COOLING SYSTEMS (LC) for the oil pan bolts, or BRAKE SYSTEM (B) for caliper mounting bolts—lists its own torque specs. You don’t have to guess. You don’t have to call a buddy who once owned a 200SX. It’s printed right there, factory-approved.

3 Reasons OEM Documentation Beats Aftermarket Reprints

First, the wiring diagrams. The ELECTRICAL SYSTEM section (E) covers the entire car—lights, ignition, starting, charging. Aftermarket scanners often drop a ground or swap wire colors. Second, the troubleshooting charts. Each section includes TROUBLE DIAGNOSES AND CORRECTIONS that list likely causes and the corrective action. That’s not something a third-party outfit bothers to reproduce. Third, the special service tool list. If you need the SST to pull a bearing, the part number is there. You can order it instead of improvising with a socket and a hammer.

Get the Right Specs for the Brake System

Section B–BRAKE SYSTEM covers disc and drum brakes. If you’re replacing pads or shoes, you need the rotor runout spec and the brake drum diameter limit. This manual gives you those numbers. Same for the FRONT AXLE FRONT SUSPENSION (F) and REAR AXLE REAR SUSPENSION (R)—the alignment angles, the ball joint torque, the wheel bearing preload. The PROPELLER SHAFT DIFFERENTIAL CARRIER (P) section tells you the pinion bearing preload. That’s the kind of data that keeps a driveline from vibrating at 70 mph.

I’ve got a stack of aftermarket manuals in the corner of my shop that I use for door stops. For real work, I pull the OEM manual. If you’re doing a CLUTCH replacement (Section C) or working on the MANUAL TRANSMISSION (M) or AUTOMATIC TRANSMISSION (A), you’ll want the factory cross-sectional drawings and the shift fork adjustment specs. They’re all here.

External sources like Automotive Industry Overview show that OEM documentation quality is unmatched. The Automotive Industry Overview backs that up with data on repair accuracy.

Does this manual cover the automatic transmission?

Yes. Section A–AUTOMATIC TRANSMISSION includes disassembly, assembly, and hydraulic circuit testing.

What about the cooling system?

Section LC–ENGINE LUBRICATION COOLING SYSTEMS covers the water pump, thermostat, radiator, and fan. Torque specs for the water pump bolts are listed in that section’s service data.

Can I use this manual for a 1981 model?

No. This is specifically for the 1980 model year. Nissan made changes to the emissions system and wiring for 1981.

How do I find the suspension alignment specs?

Section F–FRONT AXLE FRONT SUSPENSION and Section R–REAR AXLE REAR SUSPENSION contain the factory alignment angles, including caster, camber, and toe. The pages are numbered separately within each section, so use the section contents list at the beginning.

You’re not going to find a better source for this car’s repair data. The 572 pages are what your local dealer would have used in 1980.
