Valve Clearance: Adjustments

NOTE:
- Valves should be adjusted only when the cylinder head temperature is less than 100°F (38°C).
- After adjusting, retorque the crankshaft pulley bolt to 177 Nm (18.0 kgs.cm, 130 ft.lbs.)

1. Remove the cylinder head cover.

2. Set No. 1 piston at TDC. The "UP" mark on the pulley should be at the top, and TDC grooves on the pulley should align with the pointer on the back cover. TDC grooves (white paint) on the crankshaft pulley should align with the pointer on the timing belt lower cover.





Number 1 piston at TDC:

3. Adjust valves on No. 1 cylinder.

Intake: 0.15 - 0.19 mm (0.006 - 0.007 inch)
Exhaust: 0.17 - 0.21 mm (0.007 - 0.008 inch)





4. Loosen the locknut, and turn the adjusting screw until the feeler gauge slides back and forth with a slight amount of drag.





Adjusting screw location:





5. Tighten the locknut and recheck clearance. Repeat adjustment if necessary.

6. Rotate the crankshaft 180° counterclockwise (camshaft pulley turns 90°). The "UP" mark should be on the exhaust side. Adjust valves on No. 3 cylinder.





Number 3 piston at TDC:

7. Rotate the crankshaft 180° counterclockwise to bring No. 4 piston to TDC. The sups mark should be pointing straight down. Adjust valves on No. 4 cylinder.





Number 4 piston at TDC:

8. Rotate the crankshaft 180° counterclockwise to bring No. 2 piston to TDC. The "UP" marks should be on the intake side. Adjust valves on No. 2 cylinder.





Number 2 piston at TDC:
