Toyota 2L-T, 3L 1990 Repair Manual

If you’re working on a Toyota 2L-T or 3L diesel and you’re relying on a generic online PDF, stop. You’re gambling with torque specs and timing marks that can sink a head gasket job in five seconds. This supplement was printed by Toyota Motor Corporation in January 1990 specifically for the 2L-T and 3L engines mounted on the LJ70, LN106, and related series. It is not a reprint or a third-party compilation. It is the actual OEM publication you need to avoid guessing on turbocharger clearances or fuel injection timing.

Toyota 2L-T, 3L 1990 Repair Manual: What This Supplement Contains

Forty-nine pages of factory procedures that differ from the base 2L/3L manual (Pub. No. RM123E). The supplement covers engine mechanical, turbocharger system, fuel system, cooling, lubrication, starting, and charging systems. It also includes service specifications and standard bolt torque specs. If you own a HILUX or 4RUNNER with a 2L-T or 3L, this is the document that tells you exactly where the base manual stops and the turbo-specific work begins.

Engine Mechanical Section – The Critical Differences

Start on page EM-1, which states: “The following pages contain only the points which differ from the above listed manual.” That means you need both manuals. The supplement gives you troubleshooting for diesel engine diagnosis (diesel knock, hard starting, overheating) and electrical system diagnosis for the 2L-T. You also get the compression check steps and cylinder head removal procedures specific to the 2L-T. Skip this section and you risk misaligning the intake venturi system on LN 2L-T models – a mistake that will cost you hours of rework.

7 Systems Covered in the Manual

• Turbocharger System (TC) – charge pressure checks and wastegate adjustment
• Fuel System (FU) – injection pump timing and ACSD (Automatic Cold Start Device) settings
• Cooling System (CO) – thermostat and fan clutch specs
• Lubrication System (LU) – oil pump and relief valve data
• Starting System (ST) – starting motor and glow plug circuit
• Charging System (CH) – alternator output ratings
• Engine Mechanical (EM) – cylinder head, block, and piston ring gaps

Each section ends with a page of service specifications. For example, the turbocharger section lists the compressor wheel clearance limits. You will not find these numbers in a Haynes or Chilton manual. The supplement is the only source for the exact values Toyota used during production.

Does the Manual Include Turbocharger System Specs?

Yes. The TC chapter covers the CT20 turbocharger used on the 2L-T. You get the turbine shaft thrust clearance, compressor housing torque sequence, and oil feed pipe routing. The manual also includes a note about using SST (Special Service Tools) for the turbine housing removal. Do not attempt a turbo rebuild without this supplement – the torque on the center housing bolts is different from the base 3L engine. One stripped stud and you are sourcing a new turbo core.

Get the Right Tools and Safety Warnings

Page C (the appendix) lists the SST and SSM (Special Service Materials) like FIPG (Formed In Place Gasket) Part No. 00295-00103. The manual warns you to use Toyota-approved sealant on the intake manifold gasket for the 2L-T. Ignore that and you will chase vacuum leaks for a week. Before you start any fuel system work, disconnect the battery and relieve the high-pressure injection line – the supplement tells you exactly how. This is the same procedure Toyota expects its dealership technicians to follow.

For the base 2L/3L engine repair manual, check the TOYOTA 2L 2L-T 3L 5L Engines 1997 Repair Manual – Section: Index Alphabetique Id. If you need a more complete set that combines the supplement with the main manual, the Toyota 2L-T, 3L 1990 Repair Manual – OEM Supplement is the exact PDF you are looking at. For later model years, the Toyota Land Cruiser, 2L, 3L, 5L, Hilux 1999 Repair Manual – OEM Specs covers the 5L engine as well. Outside sources like Toyota’s own owner resources Automotive Industry Overview can give you general maintenance schedules, but for engine repair you need the factory supplement.

Is this manual for the 2L engine as well?

No. This supplement covers only the 2L-T and 3L engines. For the normally aspirated 2L you need Pub. No. RM123E.

What models does this manual apply to?

It covers the LJ70, 72, 73, 77, 79 series and LN106, 111, 130, 135 series. That includes the Toyota Land Cruiser, HILUX, and 4RUNNER with 2L-T or 3L. The manual explicitly notes that basic engine service procedures are in the 2L, 3L Engine Repair Manual (RM123E). You must own both to complete a full overhaul. The supplement only contains the differences – turbocharger system, revised fuel injection pump settings, and ACSD calibration. Without the base manual you will miss the timing belt replacement steps and valve clearance specs. Order both if you are serious about a correct rebuild.

Aftermarket documentation will tell you the torque is “tight enough.” Factory documentation tells you the exact inch-pound for the injector hold-down bolts. Stop chasing aftermarket rumors. Download the Factory Manual and get the real specs Toyota released in 1990.
