EXHAUST PIPE INSTALLATION

CAUTION / NOTICE / HINT

Note:

When removing or installing the center exhaust pipe assembly, do not subject the temperature switch to impacts.

PROCEDURE

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

    1. A128853

      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 the minimum, replace the compression spring.
