1Part I EngineChapter 1 Engine Assembly
(MR479Q, MR479QA, MR481QA)Section 1 Routine Inspection1. Check coolant
2. Check engine oil
3. Check battery
4. Check air cleaner element assembly
5. Check spark plug
6. Check drive belt
Figure 1
Notice:
zCheck the belt deflection at the specified point See (Figure 1).
zSet tension to specified value when installing new belt.
zCheck the deflection to ensure it is below the specified value after the belt runs for over 5 minutes.
zReinstall the belt which has been running for over 5 minutes. The deflection of the old belt is regarded as
the standard for inspection.
zCheck 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 idleFigure 2New Belt mm Old Belt mm

2c) When fault diagnosis tester is not used
(1) Shorting fault diagnosis interface socket 13 (TC) terminal and 4(CG) terminal.
Notice:
zEnsure correct connection, otherwise the engine will be damaged.
zSwitch off all electrical appliance system.
zCheck 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)
Notice:
zCheck idle when cooling fan motor is disconnected.
zSwitch off all electrical accessories and A/C.
9. Check compression pressure See (Figure 4)
(a) Engine switched off.
(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. MR479Q 800±50 (rpm)
MR479Q A 800±50 (rpm)
MR481Q A 800±50 (rpm)Table 2(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
9 when not using fault tester.
(d) Check idle See (Table 2).
Figure 4Figure 3Techometer
Battery

3The Min. compression pressure: 980 kPa
The tolerance range of the cylinders pressure: 100 kPa
Notice:
zEnsure sufficient battery power and the engine speed is no less than 250 RPM (revolutions per minute).zCheck the compression pressure of other cylinders in the same way.
zComplete 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:
zIf the compression pressure is improved after filling oil, the piston ring or the cylinder may be abrased
or damaged.
zIf 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:
zComplete measurement within 3 minutes.
zTest 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.
