Engine mechanismEngine assemblyInspection1. Check coolant.
2. Check engine oil.
3. Check battery.
4. Check air filter assembly.
5. Check spark plug [4G18-3705113].
6. Check drive belt [4G18-1307107].Hint: do not check belt tension, because automatic tensioner is applied.7. Check ignition timing.(a) Warm up engine.
(b) Connect timing lamp to engine.
(c) Check ignition timing at idle speed.
Ignition timing: before top dead center Note: when checking ignition timing, place
transmission at neutral position.
Hint: After run the engine for 5 seconds with rotating
speed of 1000-1300rpm, check the engine could
recover to idle running.8. Check engine idle speed.(a) Warm up engine and run it at idle speed.
(b) Read engine rotating number in data flow with diagnostic instrument.
(c) Check idle speed.
Idle speed: about 750-850rpm
Notes:When checking idle speed, place cooling fan at OFF position.Turn off all auxiliary devices and air conditioner.Engine mechanism - Engine assemblyK-line 26

9. Check compression pressure.(a) Warm up engine.
(b) Remove ignition coil.
(c) Remove spark plug.
(d) Check cylinder compression pressure.
(1) Install cylinder compression pressure gauge on spark plug hole.
(2) Wide open throttle.
(3) Measure the pressure during crankshaft rotating.
Notes:Ensure to use fully charged battery to make the rotating speed of engine reach or exceed 250rpm.When measuring other items, please repeat steps (1) to (3). Finish the measurement as soon as possible.
Compression pressure: 1080kPa
Min pressure: 1000kPa
Difference among cylinders: 100kPa
(4) If the compression pressure of one or more cylinders is too low, inject a small amount of engine oil
from spark plug hole into the cylinder with low pressure, and repeat steps (1) to (3) to check
pressure.If the pressure increases after engine oil is injected, the piston ring of this cylinder or the
cylinder has been worn or scratched.If the pressure is still too low, the valve may be stuck or not fully closed, or the cylinder head
gasket leaks.10. Check CO/HC.(a) Start engine.
(b) Keep the rotating speed of engine at 2500rpm for about 180 seconds.
(c) When the engine is idle running, insert the test bar of CO/HC gauge into exhaust pipe at least 40cm.
(d) Immediately check idle speed and CO/HC concentration at 2500rpm.
Hints:Finish test within 3 minutes.Perform the test under 2 analog states (idle speed and 2500rpm) according to measuring meth-
ods and sequences specified by Emission Regulations.
(e) If CO/HC concentration is not within specified value, perform trouble shooting according to the
following sequences.
(1) Check the function of oxygen sensor.
(2) See possible failure causes listed in the table below, and repair and correct if necessary.Engine mechanism - Engine assembly27

2. Remove ignition coil components [4G18-3705110].
3. Remove cylinder head cover components [4G18-
1003130].
4. Remove engine right bottom shield.
5. Turn crankshaft to cylinder 1 compression top dead
center position.(a) Turn crankshaft pulley to align its groove with “o” mark on
timing chain hood.
(b) Check dot marks on camshaft timing sprocket and VVT
timing sprocket, and they should be in a line on timing chain
hood surface as shown in the diagram.
Hint: if not, turn crankshaft for one circle again
and align the above marks.6. Check valve clearance.(a) Only check the valves shown in the diagram.
(1) Measure the clearance between valve tappet and cam-
shaft with plug gauge.
(2) Record valve clearance measuring value exceeding
specification, and this value will be used to determine
valve tappet thickness that needs change.

turned to compression top dead center position.
(c) Only check the valves shown in the diagram. Measure valve
clearance (see step (a)).7. Remove drive beltSlowly turn drive belt tensioner clockwise to loosen it.
Then remove drive belt and put back drive belt tensioner slowly
and gently. 30 Mark
