When I step on the gas the engine fan gets loud like a plane is about to take off./
If not fix - what damage could it cause?
center pulley w/ fan attached is wobbling and chirping, not sure if this the water pump or not?
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.
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.
Fan clutch makes a roaring sound when the engine is accelerated.
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.
Radiator fan runs very fast and very loud when I step on the gas with low power.
Fan clutch Makes a roaring noise and turns the SES light on when running the a/c
Same issue was told it was fan clutch. just had replaced and now the damn thing is ticking. took it back and they said it was normal! it never ticked before and I have had the car for a year!
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.
Needed to replace fan clutch
