WASHINGTON, D.C. --- Illinois-based Navistar is recalling over 7,500 MY 2009 International Model trucks and MY 2009 and 2010 IC school and transit buses -- manufactured between April 1, 2008 and Dec. 12, 2008 -- that are equipped with a Horton two-speed fan drive. 

According to the National Highway Traffic Safety Administration's website, the fasteners that connect the magnet brackets to the air chamber housing of the two-speed engine fan could fail, resulting in the magnet bracket being thrown from the fan drive and the vehicle at high speed. As a consequence, the bracket could separate and strike a person or motor vehicle. This is turn could lead to property damage, personal injury or even death, the NHTSA said. 

The fan drive is identified by feature code 12THT. 

Navistar will notify owners and repair the vehicles by replacing the engine fan drive air chamber and magnet brackets free of charge. The safety recall is expected to begin around June 1. Owners can contact Navistar at (800) 448-7825.
