Check Engine Light illuminated and took the car to the dealer to have it checked. They ran a diagnostic test and said the Cooling Fan Clutch needed to be changed. Cost $1185.00. Outrageous! Read other same complaints about cooling fan clutch. With the number of complaints, shouldn't this be a recall also?

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.

Needed to replace fan clutch

The fan clutch will not engage. My lights have not came on as of yet. I can't afford to have the engine over heat. The part costs way to much. I believe if the envoy is doing this it should be a recall.

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.

Fan clutch intermittently locks up creating noise and check engine situation. The code reads cooling fan speed too high. Replacement fan clutch does same thing.
