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.)
