INSPECTION
1. INSPECT ENGINE COOLANT (See page 16-6)
2. INSPECT ENGINE OIL
3. INSPECT BATTERY
4. INSPECT AIR CLEANER FILTER ELEMENT SUB-ASSY
5. INSPECT SPARK PLUG (See page 18-3)
6. INSPECT V-RIBBED BELT
HINT:
After installing the drive belt, check that it fits properly in
the ribbed grooves. Check with your hand to confirm that
the belt has not slipped out of the groove on the bottom
of the crank pulley.
ºNew beltº is a belt which has been used less than 5 min-
utes on a running engine.
ºUsed beltº is a belt which has been used on a running en-
gine for 5 minutes or more.
After installing a new belt, run the engine for approximate-
ly 5 minutes and then recheck the tension.
7. INSPECT IGNITION TIMING
(a) Warm up the engine.
(b) When using the hand-held tester:
Check the ignition timing.
(1) Connect the hand-held tester to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester.
Ignition timing: 8 to 12 BTDC @ idle
HINT:
Please refer to the hand-held tester operator's manual for help
on selecting the DATA LIST.
(c) When not using the hand-held tester:
Check the ignition timing.
(1) Using SST, connect terminals 13 (TC) and 4 (CG)
of the DLC3.
SST 09843-18040
NOTICE:
Confirm the terminal numbers before connecting
them. Connection with a wrong terminal can damage
the engine.
Turn off all electrical systems before connecting the
terminals.
Perform this inspection after the cooling fan motor is
turned off.

(2) Remove the cylinder head cover No. 2.
(3) Pull out the wire harness as shown in the illustration.
Connect the clip of the timing light to the engine.
NOTICE:
Use a timing light which can detect the first signal.
After checking, be sure to tape the wire harness.
(4) Check the ignition timing at idle.
Ignition timing: 8 to 12 BTDC @ idle
NOTICE:
When checking the ignition timing, the transmission
should be in the neutral position.
HINT:
After engine rpm is kept at 1,000 to 1,300 rpm for 5 seconds,
check that it returns to idle speed.
(5) Remove the SST from the DLC3.
SST 09843-18040
(6) Check the ignition timing at idle.
Ignition timing: 5 to 15 BTDC @ idle
(7) Confirm that ignition timing moves to the advanced
angle side when the engine rpm is increased.
(8) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up the engine.
(b) When using the hand-held tester:
Check the idle speed.
(1) Connect the hand-held tester to the DLC3.
HINT:
Please refer to the hand-held tester operator's manual for fur-
ther details.
(2) Enter DATA LIST MODE on the hand-held tester.
Idle speed: 610 to 710 rpm
NOTICE:
When checking the idle speed, the transmission
should be in the neutral position.
Check idle speed with the cooling fan off.
Switch off all accessories and air conditioning before
connecting the hand-held tester.
(c) When not using the hand-held tester:
Check the idle speed.
(1) Using SST, connect tachometer tester probe to ter-
minal 9 (TAC) of the DLC3.
(2) Check the idle speed.
Idle speed: 610 to 710 rpm
