Publication Date: February 1, 2011

FORD:
2008-2010 F-Super Duty

This article supersedes TSB 8-25-1 to remove the production build date, update the vehicle model years and Part List.

ISSUE:

Some 2008-2010 F-Super Duty 250-550 vehicles equipped with a 6.4L diesel engine may exhibit significant amounts of white smoke from the exhaust pipe while driving in high humidity or rainy conditions at temperatures above 4 °C (40 °F). This smoke only appears during a moderate to full throttle tip-in that is performed after a period of steady state driving.

ACTION:

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

This procedure only applies if the vehicle meets the following criteria:

  • Concern is described as significant amounts of white smoke from the exhaust pipe.
  • White smoke only occurs in high humidity or rainy conditions above 4 °C (40 °F).
  • White smoke only appears during a moderate to heavy tip-in that is performed after a period of steady state driving (approximately 20 minutes)
  • No diagnostic trouble codes (DTCs) are present.
  • Concern is not a result of regeneration, a cleaning exhaust filter event.

If all of the criteria above is true, then replace the charge air cooler (CAC) assembly with a new revised part per Workshop Manual, Section 303-12.

Some white smoke may still be present under severe conditions even after the new level CAC has been installed. This is considered a design characteristic of the charge air system and no repair attempts should be made. This concern does not affect the life of the engine or exhaust components.
