my fan clutch was stuck when i purchased my envoy 2 years ago and i just finally changed it last month. wish i done it sooner because i cant believe the amount of strain that thing put on my engine not to mention the gas. what a difference now. So quiet and the truck has so much more power and way better gas mileage, i got my new one off ebay for 75.00 where as auto zone wantes 200.00.
when i researched about it i found that it could be a number of things other than the clutch to keep it engaging. however i finally just took a chance and replaced the fan clutch itself, glad i did.
Mine would only disengage after getting up past 40mph or so for an extended time but every time i came to a stop i get the mack truck sound again. Kick myself for letting it go so long.
not sure if my post was helpful but just wanted to add my experience
