2. Remove the front muffler.

3. Remove the cooling fan assembly.

4. Remove oil level gauge assembly.

5. Remove the LH exhaust manifold heat protector (A).

Tightening torque :
9.8 - 11.8N.m (1.0 - 1.2kgf.m, 7.2 - 8.7lb-ft)




6. Remove the LH exhaust manifolds stay (A),and then remove the LH exhaust manifold (B) and gasket.

Tightening torque
Stay bolt :
24.5 - 35.3N.m (2.5 - 3.6kgf.m, 18.1 - 26.0lb-ft)
Manifold nuts :
49.0 - 53.9N.m (5.0 - 5.5kgf.m, 36.2 - 39.8lb-ft)




7. Installation is reverse order of removal.

NOTE:
When installing the exhaust manifold, tighten the nuts with pre-torque first and then tighten the nuts with specified torque in the sequence shown.
