ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN

Issued by FREIGHTLINER LLC · Reported Sep 6, 2005 · 1,395 vehicles affected

What's wrong

CERTAIN MY 2004 FREIGHTLINER BUSINESS CLASS M2 AND THOMAS BUILT SAF-T-LINER C2 SCHOOL BUSES MANUFACTURED BETWEEN JULY 26 AND OCTOBER 29, 2004, EQUIPPED WITH A CATERPILLAR C-7 ENGINE AND BORG-WARNER KYS 4735 35480 55 ENGINE FAN. THE FAN SHROUD MAY BE DRAWN BACK INTO THE FAN AT HIGH ENGINE SPEEDS WHEN THE FAN CLUTCH ENGAGES. DUE TO REDUCED CLEARANCE, HEAVY CONTACT BETWEEN THE FAN AND THE SHROUD MAY CAUSE THE FAN BLADE TO FRACTURE.

Consequence

THE FAN MAY FRACTURE AND PIECES MAY SEPARATE FROM THE FAN BLADE. IN CERTAIN CONDITIONS, THIS MAY PRESENT A HAZARD TO PEOPLE NEAR THE VEHICLE WITH THE HOOD OPEN AND THE ENGINE RUNNING.

Remedy

FREIGHTLINER WILL NOTIFY ITS CUSTOMERS AND REPLACE THE ENGINE FAN WITH A FAN THAT HAS A DIFFERENT MOUNTING OFFSET FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON JANUARY 16, 2006. OWNERS MAY CONTACT FREIGHTLINER AT 1-800-547-0712.
