INSTALLATION SERVICE POINT

>>A<< CYLINDER HEAD GASKET/CYLINDER HEAD ASSEMBLY INSTALLATION
1.
caution Be careful that no foreign material gets into the cylinder, coolant passages or oil passages. Engine damage may result.
Use a scraper to clean the gasket surface of the cylinder head assembly and cylinder block.
2.Install the cylinder head gasket and cylinder head assembly to the cylinder block.

3.Check in the following procedure before reusing the cylinder head bolt.
(1) Measure the outside diameter "A".
(2) Measure the smallest outside diameter "B" within the range "X" shown in the illustration.
(3) If the difference of outside diameter of thread exceeds the limit, replace the cylinder head bolt.
Limit: 0.1mm

4.Tighten the cylinder head bolts to the specified torque in the order shown in the illustration (in two or three cycles).
Tightening torque: 45 ± 2 N·m

5.
caution
  • If the cylinder head bolt is turned less than 152° ± 2°, proper fastening performance may not be achieved. Be sure to turn the cylinder head bolt exactly 152° ± 2°.
  • If the cylinder head bolt is overtightened, loosen the cylinder head bolt completely and then retighten it by repeating the tightening procedure from step 3.
Using special tool angle gauge (MB991614), tighten the cylinder head bolt another 152° ± 2° again.
