REMARKS:
Major service interval at 12 months/20,000 km (12,000 Miles), Lubrication service based on distance only 10,000 km (6,000 Miles) not time
After 80,000 km (48,000 Miles) or 48 months, continue to follow the described maintenance items and intervals periodically.
As for * marked items in this maintenance chart, please pay attention to the following points.
*1 Replacement of the timing belt is required at every 100,000 km (60,000 Miles). Failure to repace the timing belt may result in damage to the engine.
*2 If the vehicle is operatie under the following conditions, it is suggested that the engine oil and oil filter be changed more often than at usual recommended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c) Driving for a prolonged period in cold temperatures or driving only short distances regulary.
*3. If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more often than at usual recommended intervals.
*4. This is a full function check of all electrical systems, i.e., all lights, washers (including condition of blades) electrical windows, sunroof, horn, etc....
*5. Replace every two years.
If there has been continuous hard driving, mountain driving, or if the brakes are used extensively or the vehicle is operated in extremely humid climates, the
brake fluid should be changed annually.

Valve Clearance (8-valve)
1. Warm up the engine to the normal operating tem-
perature.
2. With the piston of the No.1 cylinder at TDC of com-
pression stroke.
Adjust the valve clearance as shown in the figure.
Valve clearance (valve side)
IN : 0.30 mm (0.012 in)

3. Turn the crankshaft one full turn so that the piston
of the No.4 cylinder is at TDC of compression
stroke.
Adjust the clearances of the remaining valves.
Ignition Timing
1. Warm up the engine and run it at idle.
2. Turn all electric loads OFF.
3. Connect a timing light tester.
4. Disconnect the vacuum hose from the vacuum
control, and plug the hose.
5. Check that the ignition timing mark (yellow) on the
crankshaft pulley and the timing mark on the tim-
ing belt cover are aligned.
Ignition timing: 6° ±

Valve spring
Cylinder head side
Valve spring
1. (12-valve)
Install the valve spring with the narrower pitch to-
ward the cylinder head side.
(8-valve)
Install the outer valve spring with the narrower pitch
toward the cylinder head side.
2. Install the valve keepers, and tap the end of the
valve stem lightly two or three times with a plastic
hammer to confirm that the keepers are all fully
seated.

12-valve Rocker arm, rocker arm shaft
1. Remove the rocker arm shafts and camshaft caps.
2. (12-valve)
Assemble the rocker arms and springs to the shaft.
Note
a) The intake side shaft has twice as many oil
holes as the exhaust side shaft.
b) The stepped ends are the rear sides of both
intake and exhaust shafts.
76G01A-039
(8-valve)
Assemble the camshaft caps, rocker arms, and
springs, to the shafts.

Valve guide
Cylinder head
76G01A-057
(2) Method No. 2
Measure the valve stem play at a point close
to the valve guide with the valve lifted slightly
off the valve seat.
Clearance
IN : 0.025—0.060 mm (0.0010—0.0024 in)
EX: 0.030—0.065 mm (0.0012—0.0026 in)
Maximum: 0.20 mm (0.0079 in)
7. If the clearance exceeds the maximum, replace the
valve and/or valve guide.
8. Check that the valve guide projection height
(dimension A in the figure). Replace if necessary.
Height:
19.8—20.3 mm (0.780—0.799 in)... 12-valve
19.1—19.6 mm (0.752—0.772 in)...8-valve
