3.INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Front and Rear Catalyst)
Using a vernier caliper, measure the free length of the compression springs.
| Minimum (front) | 41.5 mm (1.63 in.) |
| Minimum (rear) | 38.5 mm (1.52 in.) |
If the free length is less than minimum, replace the compression spring.
Temporarily install 2 new gaskets to the exhaust manifold and front exhaust pipe assembly (TWC: Front and Rear Catalyst).
| *1 | Exhaust Manifold or Front Exhaust Pipe Assembly (TWC: Front and Rear Catalyst) |
| *2 | Gasket |
| *a | Wooden Block |
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 (TWC: Front and Rear Catalyst).
- NOTICE:
- ·
Be sure to install the gaskets in the correct direction.
·Do not reuse the gaskets.
·Do not damage the gaskets.
·Do not push in the gaskets by using the exhaust pipes when connecting them.
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.
| *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 front exhaust pipe assembly (TWC: Front and Rear Catalyst) to the tail exhaust pipe assembly with the 2 compression springs and 2 bolts.
- 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.
