Valve Clearance: Adjustments
VALVE CLEARANCE ADJUSTMENTNOTE:
- Valves should be adjusted cold when the cylinder head temperature is less than 38°C (100°F).
- Adjustment method is the same for intake and exhaust valves.
- If the pulley bolt loosens while turning crank, tighten it to specified torque.
Specified Torque: 185 Nm (18.5 kg/m. 134 lb/ft)
1. Remove the cylinder head cover.
2. Set No. 1 piston at TDC. "UP" mark on the pulley should be at top, and TDC groove should align with pointer(s) on the timing belt back cover. The crankshaft pulley should be at TDC.
3. Adjust valves on No. 1 cylinder.
Intake: 0.18-0.22 mm (0.007-0.009 in)
Exhaust: 0.23-0.27 mm (0.009-0.011 in)
4. Loosen locknut and turn adjustment screw until feeler gauge slides back and forth with slight amount of drag.
5. Tighten locknut and check clearance again. Repeat adjustment if necessary.
6. Rotate crankshaft 180° counterclockwise (cam pulley turns 90°). The "UP" mark should be at exhaust side. Distributor rotor should point to No, 3 plug wire. Adjust valve on No. 3 cylinder.
7. Rotate crankshaft 180° counterclockwise to bring No. 4 piston to TDC. Both TDC grooves are once again visible and distributor rotor should point to No. 4 plug wire. Adjust valves on No. 4 cylinder.
8. Rotate crankshaft 180° counterclockwise to bring No. 2 piston to TDC. The "UP" mark should be at intake side. Distributor rotor should point to No. 2 plug wire. Adjust valves on No. 2 cylinder.
