EXHAUST MANIFOLD W/ TURBOCHARGER PRECAUTION


  1. MAINTENANCE PRECAUTION


    1. Do not stop the engine immediately after pulling a trailer, driving at a high speed, or driving uphill. Let the engine idle for 20 to 120 seconds before turning the ignition switch off. According to the driving conditions, vary the idling time.

    2. Avoid quick acceleration or quickly increasing the engine speed immediately after starting a cold engine.

    3. If the turbocharger sub-assembly is found to be defective, it must be replaced. Also, inspect the source of the trouble including the conditions under which the turbocharger sub-assembly was used. Repair or replace the following as necessary:


      1. Engine oil (level and quality)

      2. Oil lines leading to the turbocharger sub-assembly

    4. Pay due attention when removing and reinstalling the turbocharger sub-assembly. Do not drop, strike, or grasp easily-deformed assembly parts.

      Note


      • B003JG9

        Do not hold the actuator or control rod.

      • B003RQL

        When storing the turbocharger sub-assembly, do not store the assembly with the actuator facing down.

      • Make sure foreign matter does not enter the intake and exhaust ports and oil passage.

    5. B003OPUC01
      *1 Oil Inlet Pipe Sub-assembly
      *a Sludge

      If replacing the turbocharger sub-assembly, check for deposits in the turbo oil inlet pipe sub-assembly.

      If necessary, replace the turbo oil inlet pipe sub-assembly.

    6. Thoroughly remove any old gasket material sticking to the lubrication oil pipe flange or turbocharger sub-assembly oil flange.

    7. If replacing the bolts or nuts, use TOYOTA genuine parts to prevent breakage or deformation.

    8. B003MVLC01
      *1 Turbocharger Sub-assembly Oil Inlet Hole

      If replacing the turbocharger sub-assembly, add 20 cc (1.2 cu. in.) of fresh oil into the turbocharger sub-assembly oil inlet hole and turn the turbine wheel by hand to spread oil over the bearing.

    9. If overhauling or replacing the engine, cut the fuel supply after reassembly and crank the engine for 30 seconds to distribute oil throughout the engine.

      Then reconnect the fuel supply and allow the engine to idle for 60 seconds.

    10. Since the turbine wheel runs at an extremely high speed, if the engine is running without the air cleaner, air cleaner cap and hose, the turbine wheel will be damaged due to the entry of foreign particles.
