Note. The valves must be adjusted when the cylinder head temperature is less than 38°C. After adjustment, tighten the crankshaft pulley bolt to a torque of 177 Nm.
1. Remove the cylinder head cover.
2. Set the piston of the first cylinder to TDC. Label "UP" on the pulley should be in the upper position, and the TDC marks on the pulley should align with the indicator on the back cover. TDC marks (White paint) on the crankshaft pulley should align with the indicator on the lower timing belt cover.
3. Adjust the valves of cylinder No. 1.
- Inlet: 0.15-0.19mm
- Graduation: 0.17-0.21mm
4. Loosen the locknut and turn the adjusting screw until the dipstick slides back and forth slightly "snacking".
Adjustment screw location:
5. Tighten the locknut and check the clearance again. Repeat adjustment if necessary.
6. Rotate the crankshaft 180°counterclockwise (The camshaft pulley rotates 90°). Mark "UP" should be on the exhaust valve side.
7. Rotate the camshaft 180°counterclockwise to bring the No. 4 piston closer to the TDC. Mark "UP" should point straight down. Adjust the valves on cylinder #4.
8. Rotate the crankshaft 180°counterclockwise to bring the No. 2 piston closer to TDC. Tags "UP" must be on the exhaust valve side. Adjust the valves on cylinder #2.
