PROCEDURE

1. INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)

*1

Exhaust Manifold (TWC: Front Catalyst)

*2

Gasket

*a

Wooden Block

*b

Plastic Hammer

(1) Using a vernier caliper, measure the free length of the compression springs.

Standard Length

43 mm (1.69 in.)

Minimum Free Length

41.5 mm (1.63 in.)

If the free length is less than the minimum, replace the compression spring.

(2) Temporarily install a new gasket to the exhaust manifold (TWC: Front Catalyst).

(3) Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the exhaust manifold (TWC: Front Catalyst).

NOTICE:

  • 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 pipes when connecting them.
