|2008-2009 F-Super Duty|
This article supersedes TSB 9-4-7 to add a production fix date.
Some 2008-2009 6.4L F-Super Duty vehicles built on or before 3/16/2009 may experience a lack of power during acceleration and perhaps the illumination of the check air filter message in the instrument cluster message center. The lack of power condition may occur when the air filter element becomes packed with snow, thereby restricting required air flow to the engine.
Follow the Service Procedure steps to correct the condition.
- For vehicles built before 9/18/2007 provide a Winter Grill cover to the customer.
- Replace the electronic Filter Minder Indicator if the vehicle does not have engineering part number 8C34-9N622-AB level installed.
- Remove auxiliary snow tube. (Figure 1 – Item 1)
Figure 1 – Article 09-6-8
- Remove the air box filter cover. (Figure 1 – Item 2)
- Replace the air cleaner element only if wet or frozen.
- Attach the snow deflector gasket. Ensure the gasket is securely attached to the rim of the air box. (Figure 2)
