1990 Toyota 2L-T & 3L Diesel Engine Repair Manual Supplement (P/N RM169E)

Toyota's January 1990 2L-T and 3L Engine Repair Manual Supplement (P/N RM169E) covers the listed Land Cruiser, Hilux, and 4Runner LJ/LN applications for Europe and General markets. It supplements the 2L, 3L Engine Repair Manual, RM123E, which is required for basic engine repair and is not included.

Supplied as one 174-page English-language PDF.

• Engine repair: Compression testing, 2L-T cylinder-head removal and installation, valve-clearance shim selection, cylinder block boring, and crankshaft inspection.

• Injection pump: Removal, disassembly, reassembly, bench adjustment, air-tightness testing, and variant-specific injection timing and plunger stroke measurements.

• Turbocharger: Boost pressure testing, waste gate actuator checks, turbine shaft play inspections, removal and installation, and indicator and warning-light diagnosis.

• Cooling and lubrication: Coolant replacement, thermostat inspection, oil pressure testing, oil and filter replacement, and 2L-T oil cooler and relief valve service.

• Starting and charging: Super Glow and fixed-delay pre-heating systems, LJ starter relay checks, alternator output testing, and system wiring diagrams.

• Factory references: Component-specific torque tables, wear limits, electrical test values, shim-selection charts, and illustrated special service tool and material references.

This manual suits experienced diesel technicians; Toyota specifically states that injection-pump repair requires considerable skill and a special test bench.

2L-T and 3L Engine Repair Data

Cylinder-bore and piston grading, ring-groove clearances, full-floating piston pin oil clearances, and crankshaft runout limits support internal engine inspection. The 2L-T cylinder-head section adds piston-protrusion measurements, head-gasket selection, and cylinder head tightening sequence views.

Toyota distinguishes factory-installed gasket grades from the B, D, and F service-replacement gaskets. This helps match the replacement gasket to measured piston protrusion before parts are ordered.

The supplement also revises the connecting-rod cap nut tightening specification. Its cylinder-head precautions warn that an incorrect bolt-removal sequence can crack or warp the head.

Injection Pump, PIJ and Market Variants

Fuel-system data separates Austria-spec 2L-T pumps from other 2L-T versions, with distinct 3L settings for Hong Kong, Singapore, Malaysia, and other markets. The 3L pump list also distinguishes High Altitude Compensation (HAC) and tachometer configurations.

Austria-spec 2L-T: Pilot Injection (PIJ) actuator pressure and piston lift adjustments, throttle position sensor checks, and EGR control valve assembly removal and installation receive specific coverage.

Pump calibration: Injection pump exploded views and plunger spring shim selection charts accompany boost compensator, load sensing timer, and full-load injection volume adjustments. The thermo wax plunger, cold-start and fast-idle controls, fuel cut solenoid, and post-adjustment checks are also covered.

Tool references include SST 09275-54010 for plunger stroke measurement and the Nippondenso 95096-10380 PIJ socket.

Turbocharger and Intake Controls

Turbocharger cross-section drawings accompany diagnosis of low boost, abnormal noise, excessive oil consumption, and white exhaust smoke. The inspection procedures cover intake and exhaust leaks as well as the shaft and waste gate actuator.

The turbocharger precautions warn that foreign material entering the intake can damage the turbocharger wheels.

The intake venturi system section applies to LN 2L-T models, with separate Austrian and other-market vacuum-test illustrations. The fuel heater and vacuum switch section applies to LJ models.

Electrical, Cooling and Lubrication Coverage

Super Glow wiring diagrams distinguish Austrian and other-market arrangements. Pre-heating timer connector views and cold-start diagnostic flowcharts support checks of the timer, glow plug relays, glow plugs, resistor, and water temperature sensor. The 3L section covers fixed-delay pre-heating.

Charging circuit diagrams distinguish LJ compact alternators with IC regulators from LN conventional alternators with external regulators. Loaded and unloaded charging tests are included.

Cooling and lubrication tables separate LJ/LN capacities and heater configurations. The 2L-T procedures detail thermostat inspection and oil cooler and relief valve removal, inspection, and installation.

Diesel fuel and cooling systems involve pressure and hot fluids; follow the manual's precautions and standard workshop safety practices.

File Format and Readability

The total includes three opening pages (cover, foreword, and title/section index) and 20 appendix pages for service specifications, standard bolt torques, and SST/SSM references.
