Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
COOLING FAN COULD BE DISLODGED, DAMAGING RADIATOR AND FAN GUIDE; AND FAN COULD BREAK LOOSE, FLY OUT OF ENGINE COMPARTMENT, AND INJURE PERSONS IN THE IMMEDIATE VICINITY.
AT HIGH ENGINE SPEEDS, THE COOLING FAN ADAPTER PLATE, WHICH CONNECTS THE COOLING FAN AND THE FAN PULLEY, HAS INSUFFICIENT STRENGTH, ALLOWING CRACKS TO DEVELOP IN THE ADAPTER PLATE.
