Valve Clearance: Adjustments

Valve Arrangement:

NOTE:
- Valves should be adjusted cold when the cylinder head temperature is less than 100°F (38°C).
- After adjusting, retorque the crankshaft pulley bolt to 220 Nm (22.0 kg-m, 159 lb.ft).

1. Remove the cylinder head cover and timing belt upper cover.

Positioning "UP" Mark:

2. Set No. 1 piston at TDC. "UP" mark on the pulley should be at top, and TDC grooves on the pulley should align with cylinder head surface.
3. Adjust valves on No. 1 cylinder.

Intake: 0.24-0.28 mm (0.009-0.011 in.)

Exhaust: 0.28-0.32 mm (0.011-0.012 in.)

Adjusting Clearance:

4. Loosen locknut and turn adjustment screw until feeler gauge slides back and forth with slight amount of drag.

Rechecking Valve Clearance:

5. Tighten locknut and check clearance again. Repeat adjustment if necessary.

Number 3 Piston At TDC:

6. Rotate crankshaft 180° counterclockwise (camshaft pulley turns 90°). The "UP" mark should be at 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. Both TDC grooves are once again visible. 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"mark should be at intake side. Adjust valves on No. 2 cylinder.
