z Set tension to specified value when installing new belt.
z Check the deflection to ensure it is below the specified value after the belt runs for over 5 minutes.
z Reinstall the belt which has been running for over 5 minutes. The deflection of the old belt is regarded as
the standard for inspection.
z Check V-belt for tension and distortion after the engine cranks for 2
turns.
7. Check ignition timing See (Figure 2)
a) Warm up the engine.
b) When using fault diagnosis tester
Connect fault diagnosis tester to fault diagnosis interface socket.
Ignition timing:
MR479Q: 10 ± 2° BTDC (before top dead center) at idle
MR479QA: 10 ± 2° BTDC at idle
MR481QA: 10 ± 2° BTDC at idle
z Ensure correct connection, otherwise the engine will be damaged.
z Switch off all electrical appliance system.
z Check when disconnecting cooling fan motor.
(2) Using timing light to check ignition timing.
Ignition timing: 10 ± 2° BTDC at idle
Notice:
(1) Transmission shift lever should be in neutral position when checking ignition timing.
(2) Running engine at 1,000-1,300rpm for 5s and check at idle.
(3) Remove the tester on fault diagnosis socket.
(4) Ignition timing advance angle becomes larger when the engine roate speed is higher.
(5) Remove timing light.
8. Check engine idle See (Figure 3)
(a) Warm up the engine.
(b) Connect fault diagnosis tester to fault diagnosis interface socket.
(c) Connect tachometer testing pen to fault diagnosis socket terminal
(b) Detach high voltage cable.
(c) Detach spark plug.
(d) Check the compression pressure in the cylinder.
(1)Insert pressure gauge into the hole of the spark plug.
(2)Throttle valve full open.
(3)Crank the engine, measure the compression pressure.
2
Figure 4
The Min. compression pressure: 980 kPa
The tolerance range of the cylinders pressure: 100 kPa
Notice:
z
Ensure sufficient battery power and the engine speed is no less than 250 RPM (revolutions per minute).
z Check the compression pressure of other cylinders in the same way.
z Complete the measure as quick as possible.
(4) If the compression pressure in several cylinder is too low, fill some engine oil to the cylinder via the
hole of the spark plug. Check by repeating step 1-3.
Hint:
z If the compression pressure is improved after filling oil, the piston ring or the cylinder may be abrased
or damaged.
z If the pressure is still too low, the valve is stagnation or poor seal, or there is a leakage in gasket.
10. Check CO/HC
(a) Start engine.
(b) Running engine at 2500rpm for approximately 3 minutes.
(c) Insert CO/HC meter testing probe into tailpipe at least 40cm during idling.
(d) Check CO/HC concentration at idle and 2500rpm.
Hint:
Complete measurement within 3 minutes.
z
z Test the CO/HC emission concentration at idle and 2500 rpm on QC/T630-1999 standard.
(e) Take the following steps to diagnose the fault if the CO/HC concentration does not comply with standard .
(1) Check the oxygen sensor operation.
(2) See (Table 3) for the possible cause and check and repair.

Figure 8
(b) Align mark "K" on camshaft timing pulley to the timing mark on bearing cap. See (Figure 10) Crank 360°
(a) Turn the crankshaft pulley for 360°. Align notch to timing mark "0" on timing belt cover No. 1.

Notice:
Because the camshaft end play is quite small, keep camshaft horizontal when removing it. If not, cylinder
head may be partially damaged by the thrust force£¬it may stuck or damage camshaft when turning crankshaft.
Take the following steps to avoid the damage:
(1) Turn the pulley to access the hole on the camshaft drive gear where the counter gear is installed. See
(Figure 12).
Hint:
The above condition allows the cylinders No. 1 and No. 3 of the intake camshaft to push up the valve tappet.
Figure 12
Figure 13
(2) Remove bolt and bearing cap No. 1.
(3) Install camshaft counter gear to drive gear with service bolt. See (Figure 13).
(4) Uniformly loose and remove 8 bearing cap bolts in several passes as
shown in the figure. See (Figure 14).
(5) Remove 4 bearing caps and camshafts.
Figure 14
7
Notice:
Due to the small end play on camshaft, the cylinder head may be damaged by the thrust force when removing
it, it may stuck or damage camshaft. Take the following steps to avoid damage:
(1) Turn the crankshaft pulley to make exhaust camshaft dowel pin is a bit higher than the cylinder head. See
(Figure 15).
(2) Align the matchmark on each gear to engage intake camshaft gear and exhaust camshaft gear. See
(Figure 16).
(3) When the gears are engaged, install the intake camshaft bearing onto bearing journal.
