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 Makes a roaring noise and turns the SES light on when running the a/c

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.

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.

i have gmc envoy 2003 and i have 4 problum 1- i have replace watter pump and after fixing pump fan cluch making noice .please tel me what to do .
I had the fan clutch replaced. Parts and labor approx. $300. Check engine light still comes on; same jet engine noise. Got part from Advance Auto and had mechanic at local shop to fix. Took car back to him next day to tell him it wasn't fixed and he said he'd do research and call me back, which he never did. I have another recall on the car and am taking to the dealer. I am going to see what they say it will cost to fix it. I am sure they will say the fan clutch needs to be replaced again and it was 8 months ago it was replaced.
