3. Remove the exhaust manifold gasket.
4. Install the exhaust manifold on the gasket and tighten the nuts to the specified torque.
Tightening torque:
- 2.0L/2.4L Engines:
- M8: 25-30 Nm
- M10: 35-55 Nm
- 2.7L Engine: 25-30 Nm
Caution: Replace the exhaust manifold gasket with a new one before reinstalling.
Note: After removing the self-locking nuts, replace them with new ones.
5. Install the heat shield.
Examination
1. Check the exhaust manifold for cracks and damage.
2. Using a precision ruler and a flat feeler gauge, measure the warpage (non-flatness) of the exhaust manifold mating surface.
Non-flatness of the mating surface:
- Nominal: less than 0.15 mm
- Maximum allowable: 0.30 mm
