5. Loosen exhaust manifold mounting nuts in the reverse order in
the figure.
6. Rotate exhaust manifold.
INSPECTION AFTER REMOVAL
Surface Distortion
lUse a reliable straight edge and feeler gauge to check the flat-
ness of exhaust manifold fitting surface.
lIf it exceeds the limit, replace exhaust manifold.
INSTALLATION
lIf stud bolts were removed, replace them with new ones, and tighten them to the specified torque:
lTighten the exhaust manifold mounting nuts in the following procedure:
1. Install gasket so that the alignment protrusion faces the No. 4 port. Refer toEM-34, "
Removal and Instal-
lation".
2. Tighten the nuts in order specified in the figure.
3. Re-tighten the nuts 1 to 8.
4. Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Start engine and raise engine speed to check no exhaust gas and engine oil leaks.
