Ford Mustang 1979 Repair Manual – Factory-Authorised for 1964-1973 V8

If you’re pulling a 289 out of a ’65 fastback and the aftermarket book says “refer to factory manual” when you need the main bearing bolt torque, you know the drill. That manual you’re missing is this one. The Ford Mustang 1979 Repair Manual – Haynes 36048 – was built from a complete teardown and rebuild of the actual car. Not a reprint. Not a compilation. 290 pages of procedures that match the car on your lift, not some generic write-up.

Engine Overhaul (Pages 15-45)

Chapter 1 starts on page 15 and runs 30 pages of engine removal, disassembly, valve grind specs, and torque sequences. You get the factory firing order, ring gaps, and bearing clearances for the 260, 289, 302, 351, 390, 427, 428, and 429. No guesswork on head bolt torque – it’s listed in the spec table. If you’re rebuilding a 302 that’s been overheated, you need the deck warpage limits on page 26. I’ve seen too many guys skip that step and blow a head gasket a month later.

Cooling System Content: What Page 46 Covers

Chapter 2 is a tight 6 pages – cooling system diagnosis, water pump replacement, thermostat testing, and radiator R&R. It includes the coolant capacity in quarts and the belt tension specs. If you’re fighting an overheating 390, the flow sequence diagram on page 48 shows you the bypass circuit. Automotive Industry Overview standards are reflected in the safety warnings: never open a hot radiator cap, always use a 50/50 mix. That’s the kind of reminder that keeps your face out of the steam cloud.

Fuel System Diagnostics: Chapter 3 Details

Chapter 3 covers fuel, exhaust, and emission controls over 39 pages. Carburetor overhaul for the Autolite 2100 and 4100, fuel pump pressure tests, and emission system troubleshooting for the Thermactor and PCV. Page 58 gives you the float level adjustment step by step. If you’re chasing a lean stumble on a 351 Cleveland, the vacuum line routing diagram on page 68 saves hours of guessing. The manual doesn’t assume you have a scan tool – it gives you the test light and vacuum gauge approach that actually works on these cars.

Transmission Removal Sequence: Page 106 Procedure

Chapter 6 starts on page 106 and runs 20 pages on the transmission – both manual and automatic (C4, C6, FMX). You get the torque converter drain procedure, bellhousing alignment, and shift linkage adjustment. Page 114 has the automatic transmission clutch pack clearance specs. If you’re swapping a C6 into a car that originally had a C4, cross-reference the driveshaft length specs on page 126. Missing that step can destroy the tail housing on the first drive.

That’s the kind of detail that separates this manual from a generic PDF. The guy who wrote it – J.H. Haynes – actually removed and reinstalled every part. The photos show real grease, real tools, real hands. You won’t find “left-hand thread” hidden in a footnote. It’s right there in the procedure.

Who This Manual Actually Serves

If you own a 1964½ through 1973 Mustang with a V8 – from a 260 to a 429 – this is the manual. It covers coupe, fastback, convertible, and Mach 1. The audience includes home garage enthusiasts who want to do their own clutch replacement, as well as shops that need a quick reference for torque values on older builds. One real-world use: a customer brought in a ’68 with a slipping clutch. The aftermarket CD I had said “remove transmission”. This manual gave me the clutch disc alignment tool part number (from the tool list on page 8) and the flywheel bolt torque in ft-lbs. Job took half the time because I didn’t have to stop and think.

A short paragraph for emphasis: That saved 45 minutes of guesswork. Worth the price of the manual right there.

Source Authenticity: Why This 1979 Manual Beats a Digital Copy

This is the original Haynes North America print, not a third-party reprint or a scanned copy from a forum. The copyright is 1979, but the procedures are based on the actual 1964-1973 vehicles. Every spec comes from Ford Motor Company technical information, as stated in the acknowledgements. The index runs from page 286 – type in your subject and find the page. Compare that to a generic online manual where you scroll through ad-filled pages. 290 pages bound in paper, no battery required. If you’ve ever been stuck on the side of the road with a dead phone, you understand why paper still wins.

FAQ – Frequently Asked Questions

Does this manual cover the 429 Cobra Jet?

Yes. Page 15 lists all V8 engines covered, including the 429. The manual specifically states it covers 260, 289, 302, 351, 390, 427, 428, and 429 cubic inch engines.

Can I use this for a 1979 Mustang?

No. This manual covers Mustang models built from 1964½ through 1973. The 1979 in the title is the publication year. For a 1979-1992 Mustang, get the Ford Mustang Mercury Capri 1979-1992 Repair Manual. Also check the Ford Mustang 1994-1997 Repair Manual if you have an SN95. For diagnostics on a 2006, the Ford Mustang 2006 Troubleshooting Manual – OEM Factory Diagnostics is the right pick.

What about wiring diagrams?

Chapter 10 (Electrical system) starts on page 153 and includes wiring diagrams for the entire car – lighting, ignition, charging, and accessories. The diagrams are black and white but clearly labeled. A good test light and this chapter will get you through most electrical gremlins.

Is the torque spec table easy to find?

Torque specs are listed in each chapter. The engine chapter on page 26 has the head bolt sequence and torque values. The transmission chapter on page 114 has bellhousing bolt torque. Use the index on page 286 to find “torque” for a full list.

This manual sits on my bench next to the scan tool. When a 1969 SportsRoof comes in with a rattling top-end, I grab it before I grab my meter. That’s the level of trust a real factory-data manual earns. Download the Factory Manual and get the same reference I use.
