NOTE:
- Cover the cylinder head intake port with a clean woven stuff or vinyl cover to prevent foreign materials from entering.
- Otherwise, engine coolant may enter the intake port from the vent holes of the cylinder head causing problems in the engine combustion chambers.
Install in the reverse order of removal.
NOTE: Tighten the intake manifold bolts and nuts, in several passes as below.

Tightening torque

Step 1 (a-h): 3.9 - 5.9 N.m (0.4 - 0.6 kgf.m, 2.9 - 4.3 lb.ft)

Step 2 (1-8): 26.5 - 31.4 N.m (2.7-3.2 kgf.m, 19.5-23.1 lb.ft)

Step 3: Repeat 2nd step twice or more.
