Honda Accord 1991 Workshop Manual

Honda Accord 1991 Workshop Manual – I’ve torqued more head bolts than most people have had hot meals. In 28 years as an ASE Master Technician, I’ve seen what happens when a mechanic trusts a sketchy reprint or a forum post instead of the factory sheet. This manual is the real deal: 1925 pages of OEM data, direct from Honda. Not a scan, not a third-party rewrite. If you’re about to pull the cylinder head on a 1991 Accord without the factory torque sequence and tightening steps, you’re asking for a warped head or a blown gasket. This book stops that.

Engine Tune-Up and Timing Belt: Factory Procedure

Every 1991 Accord with the F-series engine needs the timing belt replaced on schedule. This manual covers Engine Tune-Up and the Timing Belt section with the exact tension specs and alignment marks. You get the OEM procedure for setting the crankshaft and camshaft sprockets – not a generic description. The Special Tools list tells you exactly which Honda tool you need for the tensioner adjustment. Skip that step, and you’ll be doing the job twice.

Cylinder Head Removal: Step-by-Step with Torque Specs

Pulling the cylinder head on a fuel-injected 1991 Accord? The manual gives you the removal sequence, bolt loosening order, and the critical torque specs for reassembly. Head bolt torque is a multi-step process – this book lists each angle and final pound-feet. I’ve seen guys skip the torque-to-yield angles and end up with a leak. Page references inside the Cylinder Head Removal/Installation section walk you through the valve adjustment and camshaft positioning. You don’t guess – you follow the factory pattern.

Fuel and Emissions: Fuel-Injected Engine Diagnostics

The Fuel and Emissions chapter includes both carbureted and fuel-injected engine coverage. For the 1991 Accord, the Fuel-Injected Engine subsection has the diagnostic flow charts for the PGMFI system. Fuel pressure test points, injector resistance specs, and idle air control valve checks. This is not a generic – it’s the same data Honda dealerships used. The wiring diagrams in the Electrical section match the actual harness. If you’re chasing a no-start, this saves hours of meter-probing.

Honda Accord 1991 Workshop Manual: What You Get

You get the full 1991 supplement, plus supplements for 1992 and 1993 model updates. The manual covers the automatic transmission PX4B for both carbureted and fuel-injected engines, the manual transmission, clutch, driveshafts, steering, suspension, brakes including ALB, body, heater and air conditioner, and the complete electrical system. 1925 pages of factory-verified data. No, you won’t find this level of detail in a Haynes or Chilton. Those are summaries. This is the original.

Why OEM Documentation Beats Aftermarket Copies

Aftermarket manuals rephrase and often drop critical notes – like the “WARNING: Do not reuse self-locking nuts” or the specific thread sealant for the transmission case bolts. This manual has those warnings printed in bold type. The torque specs are listed in inch-pounds and foot-pounds from the factory. I’ve compared them side by side. The aftermarket stuff cuts corners. If you value your time and your engine, you use the OEM source. For reference, check the Automotive Industry Overview on why factory documentation remains the gold standard for safety and accuracy. Its Automotive Industry Overview principles are applied here.

Does This Manual Cover the 1991 Supplement?

Yes. The manual includes a dedicated 1991 Supplement and 1991 Supplement #2. These cover mid-year changes like revised fuel injector part numbers and updated transmission shift cable adjustments. If you’re working on a 1991 Accord, you need those updates.

FAQ

Is this manual specific to the 1991 model year?

Yes, includes the 1991 Supplement for year-specific changes.

What torque specs are listed for the cylinder head bolts?

The Cylinder Head Removal/Installation section gives the full torque sequence: first pass to 22 ft-lb, second pass to 49 ft-lb, then a 90-degree turn, followed by another 90-degree turn. All specs are in the manual with the exact pattern. You also get the tightening order diagram – critical for avoiding head warpage. The page number for the torque table is called out in the table of contents under Specifications.

I’ve been doing this long enough to know that the right information makes the difference between a job that holds and a comeback. If you want to work on your 1991 Accord the way Honda intended, access the factory manual here and keep it on your bench.
