INSPECTION
HINT:
Inspect these items when the engine is cold.
1. REPLACE TIMING BELT (See page EM-15)
2. INSPECT DRIVE BELTS
(See pages CH-1, SR-3 and AC-17)
3. REPLACE SPARK PLUGS (See page IG-1)
4. INSPECT AIR FILTER
(a) Visually check that the air filter is not excessively dirty or
oily.
(b) Clean the air filter with compressed air.
First blow from the inside thoroughly, then blow off the
outside of the air filter.
5. REPLACE AIR FILTER
Replace the air filter with a new one.
6. REPLACE ENGINE OIL AND OIL FILTER
(See page LU-3)
7. REPLACE ENGINE COOLANT (See page CO-2)
8. REPLACE GASKET IN FUEL TANK CAP
(See page EC-6)
9. INSPECT FUEL LINES AND CONNECTIONS
(See page EC-6)
10. INSPECT EXHAUST PIPES AND MOUNTINGS
(See page EC-14)
11. ADJUST VALVE CLEARANCE (See page EM-4)

GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see-through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE FLUID LEVEL
Check that the brake fluid level is near the upper level line on the see-through reservoirs.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
Check the level.
The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the
fluid level is in the ºHOTº range.
(d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.
