Torque : 12 Nm (122 kgf-cm, 9 ft-lbf)

2. INSTALL EXHAUST MANIFOLD

(a) Install a new exhaust manifold gasket.

(b) Install the exhaust manifold with the 5 nuts.

Torque : 37 Nm (377 kgf-cm, 27 ft-lbf)

3. INSTALL MANIFOLD STAY

(a) Install the manifold stay with the 3 bolts.

Torque : 43 Nm (438 kgf-cm, 32 ft-lbf)

(b) Install the 2 drive shaft heat insulator sub-assemblies with the 2 nuts.

Torque : 18 Nm (184 kgf-cm, 13 ft-lbf)

4. INSTALL FRONT EXHAUST PIPE ASSEMBLY

(a) Using a vernier caliper, measure the free length of the compression springs.









HINT
If the free length is less than the minimum, replace the compression spring.

(b) Fully insert 2 new gaskets to the exhaust manifold and front exhaust pipe assembly.

(c) Using a plastic hammer and wooden block, tap in each gasket until its surface is flush with the exhaust manifold and front exhaust pipe assembly.
