3. INSTALL EXHAUST MANIFOLD RH
(a) Install the exhaust manifold RH with a new gasket and 6 nuts.
Torque: 21 N*m (214 kgf*cm, 15 ft.*lbf)
(b) Install the exhaust manifold stay with the nut and bolt.
Torque: 35 N*m (357 kgf*cm, 26 ft.*lbf) (c) Connect the air fuel ratio sensor (for Bank 1 Sensor 2) connector.
4. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Check compression springs.
(1) Check the compression springs using vernier calipers.
Specified length: 38.86 mm (1.5299 in.)
HINT:
If the result is not as specified, replace the compression spring.
(b) Install the gasket.
(1) Install a new gasket by hand onto the front exhaust pipe assembly.
(2) Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the front exhaust pipe.
NOTICE:
