Intake Manifold Bolts
Bolt Size: 3/8-16
Torque: 25 ft-lbs
NOTE: It is important to tighten the intake manifold bolts in a specific sequence to ensure even clamping force and to prevent warping of the intake manifold. The tightening sequence is as follows:
1. Front, center bolt
2. Rear, center bolt
3. Left front bolt
4. Right front bolt
5. Left rear bolt
6. Right rear bolt
7. Tighten all bolts to the specified torque in two or three passes, increasing the torque by 5-10 ft-lbs each pass.
