INSTALL FRONT EXHAUST PIPE ASSEMBLY (w/ Exhaust Heat Recirculation System)

Note

When installing the heater water hose, ensure that the exhaust heat recirculation system is filled with coolant. Otherwise, the engine water pump assembly may be damaged.

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.

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.

Note

Be careful with the installation direction of the gaskets.
Do not reuse the gaskets.
Do not damage the gaskets.
Do not push in the gaskets by using the exhaust pipe when connecting it.

Connect the front exhaust pipe assembly to the 2 exhaust pipe supports.
Install the front exhaust pipe assembly with the 4 bolts and 4 compression springs.

Torque:

43 N*m { 438 kgf*cm, 32 ft.*lbf }
Connect the 2 heater water hoses and slide the 2 clips to secure them.
Connect the 3 clamps and heated oxygen sensor connector.
