Scheme 7

Scheme 8

1. Release fuel pressure. Refer to [ «FUEL PRESSURE CHECK: QR25DE»(ref-375719-S33684214322010102800000) ]
2. Remove quick connector cap, and disconnect quick connector at the engine side. Refer to «AIR CLEANER AND AIR DUCT: REMOVAL AND INSTALLATION»(ref-375720-S00045471172010102800000) .
3. Remove air duct, PCV hose (between air duct and rocker cover) and electric throttle control actuator. Refer to «INTAKE MANIFOLD: REMOVAL AND INSTALLATION»(ref-375720-S41952777752010102800000) .
4. Disconnect harness connector of air fuel ratio sensor 1, and harness from bracket and middle clamp.
5. Remove air fuel ratio sensor 1 using Tool. Tool number: - (J-44626) CAUTION: Be careful not to damage air fuel ratio sensor 1. Discard any air fuel ratio sensor 1 which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; replace with a new one.
6. Remove exhaust front tube. Refer to [ «EXHAUST SYSTEM: EXPLODED VIEW»(ref-375741-S34517681292010102800000) ].
7. Remove exhaust manifold cover.
8. Remove bracket between exhaust manifold-three way catalyst assembly and transmission assembly.
9. Loosen nuts in reverse order as shown to remove exhaust manifold and three way catalyst assembly.
10. Remove gasket. CAUTION: Cover engine openings to avoid entry of foreign materials.

Scheme 9

1. Check the surface distortion of exhaust manifold and three way catalyst assembly mating surface with straightedge and feeler gauge. Limit: 0.3 mm (0.012 in)
2. If it exceeds the limit, replace exhaust manifold and three way catalyst assembly.

Scheme 12

1. Remove three way catalyst (RH). Refer to [ «Three Way Catalyst: Removal and Installation [VQ40DE]»(ref-375741-S24501766442010111100000) ].
2. Remove heat shield from lower dash panel.
3. Remove support bolts from A/T fluid charging pipe (A/T models). Refer to «TRANSMISSION ASSEMBLY: COMPONENT»(ref-375705-S19453451932010102800000) .
4. Loosen nuts in reverse order as shown. <==: Front NOTE: Disregard the numerical order No. 7 and 8 in removal.
5. Remove exhaust manifold (RH) and exhaust manifold cover (RH) together.
6. Remove gaskets. CAUTION: Cover engine openings to avoid entry of foreign materials.

Scheme 13

1. Check the surface distortion of the exhaust manifold mating surface with straightedge and feeler gauge. Limit: 0.3 mm (0.012 in)
2. If it exceeds the limit, replace exhaust manifold.

Install the exhaust manifold gaskets in direction as shown.
