Publication Date: September 19, 2005

FORD:
2003-2005 Excursion

2004-2006 E-Series, F-650, F-750

ISSUE:

Some 2003-2006 model year vehicles equipped with a 6.0L diesel engine may exhibit a crank time longer than 2.5 seconds in ambient temperatures above 32 F (0 C) and/or during hot restarts, or may exhibit a runs rough condition with no diagnostic trouble codes (DTCs). These conditions may be noticed at factory delivery or after a repair involving removal of high-pressure oil system components. This may be caused by air trapped in the high-pressure oil system.

ACTION:

To purge the air, drive the vehicle through at least 12 short, high-demand cycles, or until crank-time has improved (Example: 12 aggressive accelerations 25 MPH to 50 MPH (32 Km/h to 80 Km/h)). Turn off the engine for 5 minutes following the drive cycle, then restart the engine. If crank time remains above 2.5 seconds, perform normal hard start diagnostics per the PC/ED manual.

NOTE:A THREE TO FIVE (3-5) SECOND CRANK TIME MAY BE CONSIDERED NORMAL IN COLDER TEMPERATURES.

NOTE:IF THIS PROCEDURE IS NOT FOLLOWED, IT MAY TAKE MORE THAN 100 MILES OF NORMAL DRIVING TO REMOVE ALL OF THE TRAPPED AIR.

WARRANTY STATUS:

Eligible Under Provisions Of New Vehicle Limited Warranty Coverage And Emissions Warranty Coverage
