Adjust the valve clearance in the following procedures:

Special Tools

EN-47934 Valve Clearance Adjust Tool

1. Remove the air filter/resonator assembly and the relevant parts installed on the cylinder head cover.
2. Remove the cylinder head cover.
3. Remove the timing belt front cover.
4. Turn over the crankshaft to make No. 1 cylinder match with the compression top dead center. When the camshaft sprocket notch (2) is aligned with the timing belt rear cover triangle pointer (1), and the crankshaft sprocket point (3) is aligned with the oil pump housing point (4), the compression top dead center is on the ignition sequence for No. 1 cylinder.
5. Check the intake/exhaust valve clearance for No. 1 cylinder.



6. Install the valve clearance adjust tool EN-47934 on the timing belt rear cover.



7. Turn over the camshaft clockwise 120 degree to align point (1), with point (2).
8. Check the intake/exhaust valve clearance on No. 3 cylinder.



9. Turn over the camshaft clockwise 120 degree to align point (1), with point (2).
10. Check the intake/exhaust valve clearance on the No. 2 cylinder.



11. Check and adjust the valve clearance using thickness gage (1). The measured valve of valve clearance should meet the specified value. Refer to Engine Mechanical Specifications.

If not, adjust the valve clearance.

Caution: Refer to Fastener Caution in the Preface section.




12. When adjusting the valve clearance, loosen the adjust nut (1), and tighten or loosen the adjust rod (2) properly. Tighten the rocker arm adjust nut to 10 N·m (88.5 lb-in).

1. Check the valve timing.
2. After removing the high headlamp, loosen the bolts (1) and remove the timing belt front upper cover (2).



3. Turning the crankshaft clockwise twice, align the notch (2) on the crankshaft pulley (1), marked 0 , for the timing check on the timing belt front lower cover.




Note: Notch (2) should be aligned with pointer (1) to set the valve timing normally.

4. Check if the notch (2) on the camshaft sprocket is aligned with the triangle pointer (1) on the timing belt rear cover.

1. Adjust the valve timing.
2. Loosen the bolt and remove the timing belt pulley (1). In loosening the bolt, use the driver (2) in the picture as shown.



3. Remove the oil level gage guide tube (2) and the timing belt front lower cover (1).



4. Remove the timing belt tensioner (2) and the timing belt (1).



5. Using the bolt, turn the crankshaft clockwise to align the mark (4) on the crankshaft sprocket with the pointer (3) on the oil pump housing. Then, turn the camshaft to align the notch (1) with the pointer (2).




Note: Do not tighten the tensioner bolt completely.

6. Install the timing belt (1) and the tensioner (2).
7. Turn the crankshaft twice clockwise. Align the mark (3) with the pointer (4) and tighten the tensioner bolt to 15-23 N·m (11-17 lb ft).
8. Install all removed parts.
