Inspection

1. Inspect coolant

2. Inspect engine oil

3. Inspect battery

4. Inspect air cleaner filter element subassy

5. Inspect spark plug

6. Inspect fan and generator v belt

Hint

: you dont need to check the belt deflection because auto tensioner is adopted.

7. Inspect ignition timing

  1. Warm up engine.
  2.  when using handheld tester or obdii scan tool.
  1.  Connect the handheld tester or obdii scan tool to the dlc3.

Hint

: please refer to the handheld tester or obdii scan tool operators manual for further details.

  1.  when not using handheld tester or obdii scan tool.
  1.  Using sst, connect terminal 13 (tc) and 4 (cg) of the dlc3.

Notice:

Notice

:

  1.  remove the 2 nuts, 2 clips and cylinder head cover.
  2.  Pull out the wire harness as shown in the illustration.
  3.  Connect the clip of the timing light to the engine.

Notice

:

  1. Inspect ignition timing at idle.

    Ignition timing: 8 12 btdc

N

otice

: when checking the ignition timing, the transmission is at neutral position.

Hint

: after engine rpm is kept at 1,000 1,300 rpm for 5 seconds, check that it returns idle speed.

  1. Disconnect the terminal 13 (tc) and 4 (cg) of the dlc3.
  2.  Inspect ignition timing at idle.

    Ignition timing: 10 18 btdc

  3.  confirm that ignition timing moves to advanced angle side when the engine rpm is increased.
  4.  Remove the timing light.
  5.  Install cylinder head cover no.2 With the 2 nuts and 2 clips.

    Torque: 7.0 Nvm (71 Kgfcm, 62 in.Vlbf)

8. Inspect engine idle speed

  1. Warm up engine.
  2. when using handheld tester or obdii scan tool.
  1.  Connect the handheld tester or obdii scan tool to the dlc3.

Hint

: please refer to the hand held tester or obdii scan tool operators manual for further details.

    Idle speed: 650 750 rpm

Notice

:

9. Inspect compression

  1. Warm up and stop engine.
  2.  remove ignition coil.
  3.  remove spark plugs.
  4.  inspect cylinder compression pressure.

    Sst 0999200500

  1.  insert a compression gauge into the spark plug hole.
  2.  Fully open the throttle.
  3.  While cranking the engine, measure the compression pressure.

    Compression pressure
    1,300 kpa (13.3 Kgfcm2, 189 psi) minimum pressure: 1,000 kpa (10.2 Kgfcm2, 145 psi) difference between each cylinder: 100 kpa (1.0 Kgfcm2, 15 psi)

Notice

:

  1. If the cylinder compression in one more cylinders is low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat steps (1) through (3) for cylinders with low compression.

Hint

:

10. Inspect co/hc

  1. Start the engine.
  2. race engine at 2,500 rpm for approx. 180 Seconds.
  3.  insert co/hc meter testing probe at least 40 cm (1.3 Ft) into tailpipe during idling.
  4.  immediately check co/hc concentration at idle and/or 2,500 rpm.

Hint

:

  1.  if the co/hc concentration does not comply with regulations, troubleshoot in the order given below.
  1. Check heated oxygen sensor operation.
  2.  see the table below for possible causes, and then inspect and correct the applicable causes if necessary.
