REMOVAL NOTE
Intake manifold
1. Remove the ignition coil and the mounting bracket.
2. Remove the cylinder head covers.
3. Remove the intake manifold and discard the gasket.
INSTALLATION NOTE
Intake manifold
1. Apply the appropriate sealant to the intersection of the cylinder block and the cylinder head at the four corners as shown.
2. Install the new intake manifold gasket.
3. Apply the appropriate sealant to the intersection of the cylinder block and cylinder head at the four corners as in step 1.
4. Position the intake manifold with the aid of two guide studs located in position 3 and 4, and install the bolts hand-tight. Then remove the two guide studs and replace with bolts.
5. Tighten the bolts in three steps in the order shown.
Tightening torques:
Step 1: 4-8 N-m (3-6 ft-lb)
Step 2: 8-15 N-m (6-11 ft-lb)
Step 3: 15-18 N-m (11-13 ft-lb)
6. Install the cylinder head covers.
Tightening torque: 6-8 N-m (4.5-5.9 ft-lb)
7. Install the upper intake manifold and tighten the nuts.
Tightening torque: 20-25 N-m (15-18 ft-lb)
8. Install the ignition coil and mounting bracket.
Tightening torque: 26-32 N-m (19-24 ft-lb)
