Acura Integra 1998 Service Manual – The One the Dealer Techs Used

If you’ve ever tried to rebuild an Integra head using a Chilton’s manual and ended up with a snapped bolt because the torque spec was wrong, you know why this original factory manual matters. This is the 1998 Acura Integra 1998 Service Manual, 1681 pages, direct from Honda’s own service publication office. Not a reprint, not a third-party compilation. This is what the dealer techs used when you brought your car in for a valve adjustment or a timing belt job.

7 Major Systems Covered in This 1998 Integra Manual

Flip to any tabbed section and you get a dedicated table of contents, exploded views with bolt torques and thread sizes, disassembly and assembly procedures, inspection steps, testing and troubleshooting, repair, and adjustments. Sections include: General Info, Engine, Cooling, Fuel and Emissions, Transaxle, Steering, Suspension, Brakes (including ABS), Body, Heater and Air Conditioner, and Electrical (including SRS). Need charge pressure for the A/C? It’s in the HVAC section. Need the alignment specs for a dropped suspension? The Suspension chapter has them. The manual is built so you can find the first page of each section without hunting through a full contents page – every section starts with a black tab that lines up with the thumb index on the cover.

ABS Diagnostics: Factory Procedure vs Aftermarket Guesswork

The ABS chapter in this manual is the real deal – Honda’s own troubleshooting steps for the 1998 Integra’s anti-lock system. Aftermarket manuals will tell you to “check the wheel speed sensor” but leave out the resistance ranges and the exact voltage at the ECU pins. Page 1-12 (Parts Marking Locations) also warns you about SRS components – special precautions required when servicing any section marked with an asterisk. That asterisk covers Brakes (Including ABS), Steering, Transaxle, Body, and Electrical – basically anywhere an airbag or pretensioner could bite you. If you skip the factory procedure and use a generic ABS bleed sequence, you risk introducing air into the modulator. This manual gives you the Honda-approved bleed order and the exact pedal-pumping sequence.

What You Get from the OEM Wiring Diagrams

The Electrical section includes SRS and runs over 300 pages of wire colors, connector views, and ground locations. Every circuit – from the main relay to the tail lights – is drawn with Honda’s own numbering system. The diagram for the cooling fan circuit, for example, shows the relay pinouts, the thermoswitch resistance at temperature, and the test points for the ECM. You won’t find that in a Haynes or a generic PDF that’s been scanned and OCR’d three times. If you’re diagnosing a no-start on a 1998 Integra LS, the manual’s troubleshooting tree walks you through the main relay, the ignition switch, and the immobilizer (if equipped) with factory test values. Automotive Industry Overview may teach you theory, but this manual teaches you the specific 1998 Integra.

Specifications: Why You Need the Factory Numbers

Torque values, fluid capacities, valve clearances, and spark plug gaps – the Specs section at the front of this manual lists them all in imperial units for North America. The engine section gives you the head bolt torque sequence and angle for the B18B1 and B18C1. The cooling section tells you the exact coolant bleed procedure for the 1998 Integra, including the air bleed bolt location on the thermostat housing. Don’t trust a forum post that says “just tighten it to 80 ft-lb” – that’s how you end up with a warped head. The manual’s values are from Honda’s own engineering. Want to confirm the transmission fluid type? The Transaxle section specifies Honda Genuine ATF or equivalent, with a fill procedure that includes the dipstick temperature check.

Suspension and Steering: When to Use the Factory Alignment Specs

The Suspension chapter includes camber, caster, and toe specs for the front and rear. If you’ve lowered your Integra on coilovers and the alignment shop says they can’t get it within specs, you need the factory ride height specifications to calculate the adjustment ranges. The manual also covers the rear trailing arm bushing replacement procedure with the special tool part numbers – you’ll see the tool list on the first page of the Suspension section. Steering column removal and intermediate shaft alignment are covered step by step. And because the asterisk sections include SRS, the manual tells you exactly how to disarm the airbag before touching the steering wheel. Automotive Industry Overview might explain why airbags deploy, but this manual tells you how to keep them from deploying while you work.

Acura Integra 1998 Service Manual: What’s Inside That Others Don’t Have

This isn’t a reprint or a compilation from a third party. The original file was distributed by Honda for free – the first page makes that clear. AutoRepairManuals is the largest collection of OEM shop manuals in North America, and this one is the real 1998 dealer-level document. Every section (including those with SRS components) has warnings and cautions specific to the vehicle. The manual also lists the under-hood emissions control label and the warning/caution label locations (page 1-5). If you’re trying to pass a smog check, those label positions and the vacuum hose routing diagrams are critical. The lift and support points on page 1-9 show you exactly where to place the floor jack and safety stands – not the “just lift it on the pinch weld” advice you get online. The Special Tools section lists every Honda-specific tool you’ll need, with part numbers. You don’t have to guess.

Does this manual cover the B18C1 engine used in the Integra Type R?

Yes, this manual covers all 1998 Integra models including Type R, LS, GS, and RS. Engine specs, timing belt procedure, and valve adjustments are included for B18B1 and B18C1.

Can I use this manual for a 1999 Integra?

The 1998 manual covers the chassis and engine specs that carried over into early 1999 models, but Honda made running changes. For example, the 1999 Integra got different ABS modulator part numbers. You’d want the 1999 manual for exact torque specs on the ABS unit. That said, 90% of the engine and suspension data is identical. If you’re doing a clutch swap or timing belt, this manual will get you through. Just cross-check any electrical connector pinouts with the vehicle’s actual harness.

Is this a PDF format or a printed book?

It’s a digital access – a high-resolution PDF of the original factory manual. You can print specific pages for your workbench or view it on a tablet. The 1681-page file is fully bookmarked and searchable.

How are the wiring diagrams in this manual compared to aftermarket ones?

The wiring diagrams are OEM – color-coded (in black and white but with labels), with connector face views, pin numbers, and wire gauge. Aftermarket manuals often compress multiple years into one diagram, leading to errors. This manual is specific to the 1998 model year.

You’ve read the specs, you know the philosophy. Now get the document that will save you a head gasket failure and a trip to the dealership. Access the Factory Manual and keep it on your shop tablet or print the section you need. No more guessing, no more broken bolts. Your Integra deserves the same treatment the factory intended.
