    INSTALL CAMSHAFT TIMING GEAR ASSEMBLY


    1. A01BCSDE02

      Align the pin hole and straight pin and install the camshaft timing gear assembly to the camshaft.

      Table 1. Text in Illustration
      *1 Straight Pin
      *2 Pin Hole

    2. Lightly press the gear against the camshaft and turn the gear. Push further at the position where the pin enters the groove.

      Note:

      Be sure not to turn the camshaft timing gear assembly in the retard direction (the right angle).

    3. Check that there is no gap between the camshaft timing gear and the flange of the camshaft.

      Note:

      • Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break.

      • Be sure not to remove the other 3 bolts. If removing the bolts, exchange the camshaft timing gear assembly.

    4. With the camshaft timing gear assembly fixed in place, install the flange bolt.

    INSPECT FOR OIL LEAK


    1. Start the engine. Make sure that there are no oil leaks from the areas that were worked on.

  17. Click here

    INSPECT ENGINE OIL LEVEL


    1. Warm up the engine, stop the engine and wait 5 minutes.

    2. Check that the oil level is between the dipstick low level mark and full level mark.

      If the level is low, check for leakage and add oil up to the full level mark.

      Note:

      Do not fill with engine oil above the full level mark.

      Tip:

      A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.


      • When the engine is new, for example directly after purchasing the vehicle or after replacing the engine.

      • If low quality oil or oil of an inappropriate viscosity is used.

      • When driving at high engine speed or with a heavy load, (when towing, or), when driving while accelerating or decelerating frequently.

      • When leaving the idling for a long time, or when driving frequently through heavy traffic.

      When judging the amount of oil consumption, keep in mind that the oil may have become diluted, making it difficult to judge the true level accurately.

    INSPECT FOR COOLANT LEAKS

    CAUTION:

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


    1. Remove the radiator reservoir cap sub-assembly.

    2. Fill the radiator reservoir assembly with engine coolant, and then attach a radiator cap tester.

    3. Warm up the engine.

    4. Using the radiator cap tester, increase the pressure inside the radiator to 137 kPa (1.4 kgf/cm2, 20 psi), and then check that the pressure does not drop.

      If the pressure drops, check the hoses, radiator assembly and engine water pump assembly for leakage.

      If there are no signs or traces of external engine coolant leakage, check the heater core, cylinder block assembly and cylinder head sub-assembly.

    5. Install the radiator reservoir cap sub-assembly.

    INSPECT IGNITION TIMING


    1. Warm up and stop the engine.

      Note:

      A warmed up engine should have an engine coolant temperature of over 80°C (176°F), have an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized.

    2. When using the intelligent tester:


      1. Connect the intelligent tester to the DLC3.

      2. Start the engine and idle it.

      3. Turn the intelligent tester main switch on.

      4. Enter the following menus:

        Powertrain / Engine and ECT / Data List / IGN Advance

        Standard ignition timing
        5 to 15° BTDC at idle
        Note:

        When checking the ignition timing, the transmission should be in neutral or park.

        Tip:

        Refer to the intelligent tester operator's manual for further detail.

    3. When not using the intelligent tester:


      1. Connect the tester probe of a timing light to the wire of the ignition coil connector for the No.4 cylinder.

        Note:

        • Use a timing light that detects primary signals.

        • After checking, be sure to wrap the wire harness with tape.

      2. Start the engine and idle it.

      3. A01BHJ6E05

        Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

        09843-18040
        Table 12. Text in Illustration
        *a Front view of DLC3
        Note:

        • Confirm the terminal numbers before connecting them. Connecting the wrong terminals can damage the engine.

        • When checking the ignition timing, the transmission should be in neutral or park.

        Tip:
        • A01BCEYE09

        • After connecting terminals (TC and CG), engine speed changes to approximately 1000 to 1500 rpm for 5 seconds, and then returns to idle speed. This is because the ECM checks that the ISC (idle speed control system) operates properly.

        • Perform the inspection of the ignition timing after engine speed is returned to idle speed.

        Table 13. Text in Illustration
        *a Engine Speed
        *b Approx. 1000 to 1500 rpm
        *c 5 sec.
        *d Idle Speed
        *e Connect Terminals TC and CG

      4. Inspect the ignition timing

        Standard ignition timing
        3 to 7° BTDC at idle

      5. Disconnect terminals 13 (TC) and 4 (CG) of the DLC3.

      6. Inspect the ignition timing

        Standard ignition timing
        5 to 15° BTDC at idle

      7. Check that the ignition timing advances immediately when the engine speed is increased.

      8. Turn the ignition switch off.

      9. Remove the timing light.

        Note:

        • When checking the idle speed, the transmission should be in the neutral position.

        • Switch off all accessories and air conditioning before connecting the intelligent tester.

      5. Turn the ignition switch off.

      6. Disconnect the intelligent tester from the DLC3.

    3. A01BHJ6E06

      When not using the intelligent tester:

    INSPECT CO/HC


    1. Start and warm up the engine.

    2. Run the engine at 2500 rpm for approximately 180 seconds.

    3. Insert the CO/HC meter testing probe at least 40 cm (1.31 ft.) into the tailpipe while idling.

    4. Immediately check the CO/HC concentration at idle and at 2500 rpm.

      Tip:

      • When performing the 2-mode (2500 rpm and idle) test, follow the measurement order prescribed by the applicable local regulations.

      • If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.

    5. If the CO/HC concentration is not as specified, perform troubleshooting in the order given below.


      1. Check the air fuel ratio sensor (Click here) and heated oxygen sensor (Click here) operation.

      2. See the table below for possible causes, and then inspect and repair the applicable causes if necessary.
