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?

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.

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.

Fan clutch makes a roaring sound when the engine is accelerated.

Replaced fan and belt and thermostat and catalytic converter and o2 sensor because vehicle lost power too but still makes a loud noise. I hear from mechanics there is nothing wrong with it. It making the loud noise because the fan is actually working properly since the thermostat was fixed. I can't stand the loud noise. Is there a fix?

I have not gotten it fixed yet. I was just checking to see what the problem of my envoy sounding like a jet engine could be caused from and the cost to repair.
