2NZ-FE INTAKE / EXHAUST EXHAUST PIPE INSTALLATION
PROCEDURE
17410
1.INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Front and Rear Catalyst)
Using a vernier caliper, measure the free length of the compression springs.
| Minimum | 41.5 mm (1.63 in.) |
If the free length is less than minimum, replace the compression spring.
Temporarily install a new gasket to the exhaust manifold.
| *1 | Exhaust Manifold |
| *2 | Gasket |
| *a | Wooden Block |
Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the exhaust manifold.
- NOTICE:
- ·
Be sure to install the gasket in the correct direction.
·Do not reuse the gasket.
·Do not damage the gasket.
·Do not push in the gasket by using the exhaust pipe when connecting it.
Connect the front exhaust pipe assembly (TWC: Front and Rear Catalyst) to the 2 exhaust pipe supports.
| *1 | Exhaust Manifold |
| *2 | Front Exhaust Pipe Assembly (TWC: Front and Rear Catalyst) |
| *3 | Gasket |
| *a | Space between Flanges: 8.5 mm (0.335 in.) |
Install the front exhaust pipe assembly (TWC: Front and Rear Catalyst) to the exhaust manifold with the 2 bolts and 2 compression springs.
- Torque:
- 43 N*m (438 kgf*cm, 32 ft.*lbf)
- HINT:
-
After installation, check that the space between the flanges of the exhaust manifold and front exhaust pipe assembly (TWC: Front and Rear Catalyst) are consistent front-to-rear and left-to-right.

2.INSTALL TAIL EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression springs.
| Minimum | 38.5 mm (1.52 in.) |
If the free length is less than minimum, replace the compression spring.
Temporarily install a new gasket to the front exhaust pipe assembly (TWC: Front and Rear Catalyst).
| *1 | Front Exhaust Pipe Assembly (TWC: Front and Rear Catalyst) |
| *2 | Gasket |
| *a | Wooden Block |
Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the front exhaust pipe assembly (TWC: Front and Rear Catalyst).
- NOTICE:
- ·
Be sure to install the gasket in the correct direction.
·Do not reuse the gasket.
·Do not damage the gasket.
·Do not push in the gasket by using the exhaust pipes when connecting them.
Connect the tail exhaust pipe assembly to the 2 exhaust pipe supports.
| *1 | Tail Exhaust Pipe Assembly |
| *2 | Front Exhaust Pipe Assembly (TWC: Front and Rear Catalyst) |
| *3 | Gasket |
| *a | Space between Flanges: 6.5 mm (0.256 in.) |
Install the tail exhaust pipe assembly to the front exhaust pipe assembly (TWC: Front and Rear Catalyst) with the 2 bolts and 2 compression springs.
- Torque:
- 43 N*m (438 kgf*cm, 32 ft.*lbf)
- HINT:
-
After installation, check that the space between the flanges of the front exhaust pipe assembly (TWC: Front and Rear Catalyst) and tail exhaust pipe assembly are consistent front-to-rear and left-to-right.
3.INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
