Valve Clearance: Adjustments

NOTE:
- Valves should be adjusted cold; at a cylinder head temperature of less than 100°F (38°C).
- Adjustment is the same for intake and exhaust valves.
- After adjusting, retorque the crankshaft pulley bolt to 177 Nm (18.0 kgf.m, 130 ft. lbs.).

Adjusting Bolt Locations::

1. Remove cylinder head cover.

Number 1 Piston At TDC::

2. Set No. 1 piston at TDC. SUP" mark on the pulley should be at top, and TDC grooves on the pulley' should align with the pointer on back cover. TDC grooves (white paint) on the crankshaft pulley should align with pointer on the timing belt lower cover.
3. Adjust valve clearance 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 feeler gauge slides back and forth with a slight amount of drag.





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

Number 3 Piston At TDC::

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 4 Piston At TDC::

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

Number 2 Piston At TDC::

8. Rotate 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.
