Toyota 2L-T, 3L 1990 Repair Manual

If you’ve ever wasted a Saturday chasing a compression spec on a 2L-T diesel because the aftermarket manual skipped the turbocharger section, you know exactly why this supplement exists. That manual you grabbed off the shelf probably left out the Toyota 2L-T, 3L 1990 Repair Manual – the actual supplement Toyota issued for dealers in January 1990. 174 pages, factory binding, no copyright photocopy. This is the supplement for the 2L-T and 3L engines in Land Cruiser and Hilux models. TOYOTA 2L 2L-T 3L 5L Engines 1997 Repair Manual – Section: Index Alphabetique Id covers later years, but this 1990 edition is the one you need for these specific engines.

Engine Mechanical – What the Supplement Adds to the Base Manual

The base 2L,3L manual (RM123E) gets you started. This supplement picks up where that leaves off. The Engine Mechanical section on page 3 lists compression verification, cylinder head service, and the venturi system – procedures that changed for the 2L-T and 3L. You get the factory diagnostic tree for engine mechanical faults, separate electrical diagnostics for Austria and other markets, and the exact sequence for timing belt and head bolt torque. Torque values are not “tighten to feel” – they’re listed in ft-lb and N·m in the Standard Bolt Torque Specifications section.

Turbocharger System: Precautions and Diagnostics

Skip the warning section in this manual and you’ll be buying parts. The Turbocharger System chapter starts with precautions – things like never running the engine without the air cleaner, proper oil feed line priming, and what happens if you over-torque the turbine housing bolts. Then it drops into a diagnostic table for low boost, oil leaks, and unusual noise. Each remedy references a specific repair procedure. Toyota 2L-T 3L Engine Repair Manual Supplement 1990 is the same document, but if you need the full bound copy, this is it.

Fuel System – Does It Include Injection Timing Data?

Yes. The Fuel System chapter covers the entire injection circuit: electric fuel supply system, injection nozzles, nozzle leakage pipes, and the injection pump. Page 5 shows the repair procedure overview with torque values for injection pipes and nozzle holders – 250 kg-cm (18 ft-lb, 25 N·m) for the injection pipe nuts. The fuel section also includes a troubleshooting table for hard starting, low power, and black smoke. If you’re doing a pump overhaul, you need the base manual too – this supplement assumes you have RM123E for pump disassembly.

3 Critical Systems: Cooling, Lubrication, and Starting

Each of these has its own chapter in this supplement. The cooling system covers thermostat testing and coolant flow diagnostics – no aftermarket guesswork on opening temperatures. Lubrication gives you the oil pressure check procedure and filter replacement steps, plus the oil cooler service. The starting system is specific to the 2L-T: it includes the glow plug circuit (labeled Circuit de préchauffage in the French-language index) with resistance specs and relay testing. These systems are often skipped in generic manuals, but here they’re laid out with the same factory logic Toyota used for its techs.

Torque Specs and Service Specifications – Page References

You don’t need to hunt for torque values. The Service Specifications section (which appears as Caractéristiques d’entretien in the French TOC) lists all critical adjustments: valve clearance, injection timing, compression pressure, and fluid capacities. The Standard Bolt Torque Specifications page gives you the head bolt tightening sequence in stages – no “use blue Loctite” nonsense. These are OEM numbers, not aftermarket translations. Toyota Land Cruiser, 2L, 3L, 5L, Hilux 1999 Repair Manual – OEM Specs extends coverage to later vehicles, but this 1990 supplement is the authoritative source for the early 2L-T and 3L.

Before you start any tear-down, read the How to Use This Manual section on page 5. It shows the index system, precaution placement, and troubleshooting table format. That page alone saved me from going down a wrong diagnosis on a no-start Land Cruiser – the electrical diagnostic flow for the 2L-T starting circuit was right there, with the correct glow plug resistance values.

Frequently Asked Questions

Is this manual a reprint or a copy?

No. This is an original OEM supplement printed by Toyota Motor Corporation.

What specific models does it cover?

It covers the 2L-T and 3L diesel engines mounted on Toyota Land Cruiser L*70,72,73,77,79 series and Hilux LN106,111,130,135 series from the 1990 model year. The supplement is meant to be used together with the base 2L,3L Engine Repair Manual (RM123E). It includes updated turbocharger system diagnostics, injection timing procedures, and special tool references that were not in the earlier manual. There are separate electrical diagnostics for Austria and other regions, and full compression test specs.
