CYLINDER HEAD GASKET (w/ DPF) INSTALLATION

Note


  • When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.

  • When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.

      w/o Rear Heater 13.2 liters (13.9 US qts, 11.6 Imp. qts)

      Tech Tips


      • TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).

      • Please contact your TOYOTA dealer for further details.

      • for Cold Area Specification Vehicles:

        Please contact any authorized TOYOTA dealer or repairer or another duly qualified and equipped professional for further details.

      Note

      Never use water as a substitute for engine coolant.

    4. Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.

      If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

    5. Install the radiator reservoir cap.

    6. Using a wrench, install the vent plug.

      Torque:
      2.0 N*m  { 20 kgf*cm, 18 in.*lbf }

    7. Bleed air from the cooling system.


      1. Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.

      2. Maintain the engine speed at 2500 to 3000 rpm.

      3. Press the inlet and outlet radiator hoses several times by hand to bleed air.

        CAUTION:

        When pressing the radiator hoses:


        • Wear protective gloves.

        • Be careful as the radiator hoses are hot.

        • Keep your hands away from the radiator fan.

      4. Stop the engine and wait until the coolant cools down to ambient temperature.

        CAUTION:

        Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    8. After the coolant cools down, check that the coolant level is at the FULL line.

      If the coolant level is below the FULL line, add TOYOTA SLLC to the FULL line.

  19. BLEED AIR FROM FUEL SYSTEM


    1. A00JTRJ

      Using the hand pump mounted on the fuel filter cap, bleed air from the fuel system. Continue pumping until the pump resistance increases.

      Note


      • The maximum hand pump pumping speed is 2 strokes per second.

      • The hand pump must be pushed with a full stroke during pumping.

      • When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases.

      • If pumping is interrupted during the air bleeding process, fuel in the fuel line may return to the fuel tank. Continue pumping until the hand pump resistance increases.

      • If the hand pump resistance does not increase despite consecutively pumping 200 times or more, there may be a fuel leak between the fuel tank and fuel filter, the hand pump may be malfunctioning, or the vehicle may have run out of fuel.

      • If air bleeding using the hand pump is incomplete, the common rail pressure does not rise to the pressure range necessary for normal use and the engine cannot be started.

    2. Check if the engine starts.

      Note


      • Even if air bleeding using the hand pump has been completed, the starter may need to be cranked for 10 seconds or more to start the engine.

      • Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.

      • Use a fully-charged battery.


      1. When the engine can be started, proceed to the next step.

      2. If the engine cannot be started, bleed air again using the hand pump until the hand pump resistance increases (refer to the procedures above). Then start the engine.

    3. Turn the engine switch off.

    4. Connect the intelligent tester to the DLC3.

    5. Turn the engine switch on (IG) and turn the intelligent tester on.

    6. Clear the DTCs Click here.

    7. Start the engine.*1

    10. Allow the engine to idle for 3 minutes or more after performing the Active Test for the 5th time.

      A00JUDPE04

      Tech Tips

      When the Active Test "Test the Fuel Leak" is used to change the pump control mode, the actual fuel pressure inside the common rail drops below the target fuel pressure when the Active Test is off, but this is normal and does not indicate a pump malfunction.

    11. Enter the following menus: Powertrain / Engine and ECT / DTC.

    12. Read Current DTCs.

    13. Clear the DTCs Click here.

      Tech Tips

      It is necessary to clear the DTCs as DTC P1604 or P1605 may be stored when air is bled from the fuel system after replacing or repairing fuel system parts.

    14. Repeat steps *1 to *3.

    15. Enter the following menus: Powertrain / Engine and ECT / DTC.

    16. Read Current DTCs.

      1. Connect the intelligent tester to the DLC3.

      2. Turn the engine switch on (IG).

      3. Turn the intelligent tester on.

      4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

      5. Perform the Active Test.

        Intelligent Tester Display Test Part Control Range Diagnostic Note
        Test the Fuel Leak Pressurize common rail interior and check for fuel leaks Stop/Start

        • The fuel pressure inside the common rail increases to the specified value and the engine speed increases to 2000 rpm when the Active Test is performed.

        • The above conditions are maintained while the Active Test is being performed.

  23. INSPECT ENGINE OIL LEVEL


    1. Warm up the engine, stop the engine and wait 5 minutes. The engine oil level should be between the dipstick low level mark and full level mark.
