Exhaust Manifold -- Installation |
1. INSTALL NO. 2 EXHAUST MANIFOLD HEAT INSULATOR |
Install the heat insulator with the 3 bolts.
- Torque:
- 12 N*m{122 kgf*cm, 9 ft.*lbf}
2. INSTALL EXHAUST MANIFOLD |
Install a new exhaust manifold gasket.
Install the exhaust manifold with the 5 nuts.
- Torque:
- 21 N*m{214 kgf*cm, 15 ft.*lbf}
Temporarily install the manifold stay with the 3 bolts.
While pushing the manifold stay toward the exhaust manifold, tighten the 2 bolts labeled 1.
- Torque:
- 43 N*m{438 kgf*cm, 32 ft.*lbf}
Tighten the bolt labeled 2.
- Torque:
- 43 N*m{438 kgf*cm, 32 ft.*lbf}
4. INSTALL FRONT EXHAUST PIPE ASSEMBLY |
Using a vernier caliper, measure the free length of the compression springs.
- Minimum Free Length:
- 41.5 mm (1.63 in.)
If the free length is less than the minimum, replace the compression spring.
Install a new gasket by hand so that its surface is flush with the exhaust manifold.
- NOTICE:
- Make sure the gasket is facing the correct direction.
- Do not reuse the removed gasket.
- Do not push in the gasket while installing the front exhaust pipe.
Install the front exhaust pipe and 2 compression springs with the 2 bolts.
- Torque:
- 43 N*m{438 kgf*cm, 32 ft.*lbf}
Install a new gasket to the front exhaust pipe.
Connect the front exhaust pipe to the center exhaust pipe with the 2 bolts.
- Torque:
- 43 N*m{438 kgf*cm, 32 ft.*lbf}
5. INSTALL NO. 1 EXHAUST MANIFOLD HEAT INSULATOR |
Install the heat insulator with the 3 bolts.
- Torque:
- 12 N*m{122 kgf*cm, 9 ft.*lbf}
6. INSTALL WIRE HARNESS CLAMP BRACKET |
Install the bracket with the bolt.
- Torque:
- 60 N*m{612 kgf*cm, 44 ft.*lbf}
Attach the clamp to connect the fuel hose.
7. INSTALL AIR FUEL RATIO SENSOR |
Using SST, install the sensor to the exhaust manifold.
- SST
- 09224-00010
- Torque:
- without SST :
- 44 N*m{449 kgf*cm, 32 ft.*lbf}
- with SST:
- 40 N*m{408 kgf*cm, 30 ft.*lbf}
- HINT:
- Use a torque wrench with a fulcrum length of 300 mm (11.8 in.).
- NOTICE:
- Do not damage the sensor.
Connect the sensor connector and clamp.
8. INSTALL NO. 2 CYLINDER HEAD COVER |
Attach the 4 clips to install the cover.
- NOTICE:
- Be sure to attach the clips securely.
- Do not apply excessive force or do not hit the cover to attach the clips. This may cause the cover to break.
9. INSPECT FOR EXHAUST GAS LEAK |
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
