NOOSAOFa1. Spark plugs must spark properly to assure proper
~engine performance and reduce exhaust emission
level.Therefore, they should be replaced periodically with
new ones.
2. The new plugs should be checked for the proper gap.
Spark plug gap
1.0-1.1 mm (.039-.043 in.)
0.7-0.8 mm (.028-.031 in.)
3.Install the spark plug and tighten to 20-30 Nm (15-21
ft.lbs.).5. TIMING BELT (Replace)
NOOSBACaReplace the belt with a new one periodically to assure
proper engine performance.
For removal and installation procedures, refer to GROUP
g-Timing Belt.
6. DRIVE BELT (For Water
Pump and Alternator)
(Inspect for tension)
NOOSSBN(1) Place straight edge as shown in the illustration.
(2) Measure the deflection with a force of
100 N (22 Ibs.)rzapplied to belt mid-point between water pump pulley
-and alternator pulley. If the standard value is not
obtained, make adjustment.
Standard value:
<1.8L Engine>8.0-11.0 mm (.315-A33 in.)
<2.0L DOHC Engine>
9.0-11.5 mm (.354-.453 in.)
(3) Use a tension gauge to check the belt tension. If the
standard value is not obtained, make adjustment.
When tension gauge is used, the tension may be
measured between any two pulleys.
Standard value:
250-500 N (55-110 Ibs.)

SERVICE ADJUSTMENT PROCEDURESENGINE COOLANT LEAK CHECK
NO7FAAE1. Loosen cap.
2.Confirm that the engine coolant level is up to the filler neck.3. Install a adapter to the water outlet fitting and apply
160
kPa (23 psi) pressure. Hold pressure for tvvo minutes, whilechecking for leakage from the radiator, hose or connec-
tionsCaution
Be sure to completely clean away moisture from the
places checked.When the tester
is removed, be careful not to spill anyengine coolant from
it.
Be careful, when installing and removing the tester andwhen testing, not
to deform the water outlet fitting.
4. If there is leakage, repair or replace the appropriate part.
CAP PRESSURE TESTNO’IFBAG
1. Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gauge stops
moving.Limit:
65 kPa (9.2 psi)Standard value:
75-105 kPa (11-15 psi)
3.Replace the cap if the reading does not remain at or abovethe limit.
NOTEBe sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an
improper indication.

check the belt for wear, damage and breakage and checkthe
pulleys for damage.
