    Fan Clutch will fail, causing the cooling fan to be locked on. This results in loss of engine power, reduced fuel mileage, and a sound like there is a jet engine under the hood when accelerating. If you accelerate too hard it will set a check engine light condition for excessive fan speed.

    Have had this problem off and on. It stopped working but then restarted working. One mechanic said it wouldn't really cause any problems. Cost to fix now 261.00 for part + labor.
