EXHAUST PIPE INSTALLATION

PROCEDURE

1. INSTALL FRONT EXHAUST PIPE ASSEMBLY

   
   

   1. Install a new gasket to the front exhaust pipe assembly.

   2. Install the front exhaust pipe assembly to the exhaust manifold sub-assembly LH (TWC: Front Catalyst) with the 2 nuts.

      Torque:

      56 N*m  { 571 kgf*cm, 41 ft.*lbf }

2. INSTALL NO. 1 EXHAUST PIPE SUPPORT BRACKET (for Lower Side)

   
   

   1. Install the No. 1 exhaust pipe support bracket with the 2 bolts.

      Torque:

      22 N*m  { 224 kgf*cm, 16 ft.*lbf }

3. INSTALL FRONT NO. 3 EXHAUST PIPE SUB-ASSEMBLY

   
   

   1. Install 2 new gaskets to the front No. 3 exhaust pipe sub-assembly.

   2. Install the front No. 3 exhaust pipe sub-assembly with the 2 bolts and 2 nuts.

      Torque:

      56 N*m  { 571 kgf*cm, 41 ft.*lbf }

6. INSTALL CENTER EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)

   
   

   1. 

      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.

   2. Temporarily install a new gasket to the front No. 3 exhaust pipe sub-assembly.

   3. 

      *1	Front No. 3 Exhaust Pipe Sub-assembly
      *2	Gasket
      *a	Wooden Block

      Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the front No. 3 exhaust pipe sub-assembly.

      Note

      
      

      • Be careful with the installation direction of the gasket.

      • Do not reuse the gasket.

      • Do not damage the gasket.

      • Do not push in the gasket by using the exhaust pipe when connecting it.

   4. Connect the center exhaust pipe assembly (TWC: Rear Catalyst) to the exhaust pipe support.

   5. Install the center exhaust pipe assembly (TWC: Rear Catalyst) to the front No. 3 exhaust pipe sub-assembly with the 2 bolts and 2 compression springs.

      Torque:

      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

      Tech Tips

      After installation, check that the space between the flanges of the center exhaust pipe assembly (TWC: Rear Catalyst) and front No. 3 exhaust pipe sub-assembly is consistent front-to-rear and left-to-right.

      

      *1	Center Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *2	Front No. 3 Exhaust Pipe Sub-assembly
      *3	Gasket
      *a	Space between Flanges: 8.5 mm (0.335 in.)

7. INSTALL TAIL EXHAUST PIPE ASSEMBLY

   
   

   1. Install a new gasket to the center exhaust pipe assembly (TWC: Rear Catalyst).

   2. Connect the tail exhaust pipe assembly to the 4 exhaust pipe supports.

   3. Install the tail exhaust pipe assembly to the center exhaust pipe assembly (TWC: Rear Catalyst) with the 2 bolts.

      Torque:

      56 N*m  { 571 kgf*cm, 41 ft.*lbf }

9. INSPECT FOR EXHAUST GAS LEAK

   If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.

   
   

   1. Perform "Inspection After Repair" after repairing an exhaust gas leak.
