AIR CLEANER ELEMENT (Replace)

The air cleaner element will become dirty and loaded with dust during use, and the filtering effect will be substantially reduced. Replace it with a new one.

1. Loosen the clamp coupling the air intake hose and the throttle body, and separate the hose.
2. Disconnect the breather hose from the rocker cover.
3. Unclasp the air cleaner cover clip.
4. Remove the air cleaner cover together with the hose.

Caution The air cleaner cover should be removed carefully, because it includes the air-flow sensor.

5. Remove the air cleaner element.
6. Set a new air cleaner element and install the air cleaner cover.



SPARK PLUGS (Replace)

1. 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-.043in.)
0.7 - 0.8 mm (.028 - .031 in.)
3. Install the spark plug and tighten to 20 - 30 N-m (15 - 21 ft.lbs.).



TIMING BELT (Replace)

Replace the belt with a new one periodically to assure proper engine performance. For disassembly and assembly procedures, refer to GROUP 9 - Timing Belt.

ALTERNATOR/WATER PUMP DRIVE BELT (Replace)

1. Place straight edge as shown in the illustration.
2. Measure the deflection with a force of 100 N (22 lbs.) applied to belt mid-point between water pump pulley and alternator pulley. If the standard value is not obtained, make adjustment.

Standard value:
7.0 - 9.0 mm (.276 - .354 in.)
9.0 - 11.5 mm (.354 - .453 in.)
