FORD:
2000-2001 EXCURSION, F SUPER DUTY

ISSUE:

Some vehicles may exhibit a “miss” sound from the exhaust. This may be caused by the design of the exhaust Y-pipe which can cause a “miss” like sound known as impingement.

ACTION:

Replace the Y-pipe with updated design to reduce “miss” sound and update the calibration of the Powertrain Control Module (PCM). Refer to the following Service Procedure for details.

SERVICE PROCEDURE

REMOVAL OF OLD Y-PIPE

  1. Raise the vehicle on a hoist.
  2. Disconnect the heated oxygen sensor electrical connections and transfer both heated oxygen sensors to the new Y-pipe. Apply a small amount of Ford Anti-Seize Compound (F6AZ-9L494-AA) (or equivalent meeting Ford specification ESE-M12A-A) to the threads on both oxygen sensors.
  3. Remove the LH and RH nuts connecting the Y-pipe to the exhaust manifolds.
  4. Remove the three (3) nuts which attach the Y-pipe to the catalytic converter and discard the gasket.

INSTALLATION OF NEW Y-PIPE

Refer to the appropriate model year Workshop Manual section 309-00 for installation instructions and specifications.

  1. Position the new Y-pipe (1C3Z-5246-AA).
  2. Install the new flange gasket (F6TZ-5C226-BA) and three (3) nuts.
  3. Install the two (2) nuts on both the right and left side Y-pipe-to-exhaust manifold connections.
  4. Connect the heated oxygen sensor electrical connections.
  5. Lower the vehicle.
  6. Reprogram the PCM with updated calibration. Refer to the following PCM Calibration Information Chart.
