Weird whooshing sound

_Spanish_ · Aug 26, 2016

So driving the other day I started noticing this weird and whooshing sound at about 2k rpms and up, engine runs fine but but this air rushing sound is driving me insane, can't seem to find what the cause of it could be.

Sounds like the fan clutch is staying in gaged or you have a bad pully.

X2 on the fan clutch comment.

Judging by the hood line Id say this is supposed to be 2000-2006? Its posted in the 2015+ section. If older model, x3 fan clutch.

OH shit my bad! Good eye! And yeah apparently I'll have to check the fan Clutch.

That wooshing sound is also a drag on your fuel economy. My 2005 & 2006 Buick Rainier every now and then would do this and I could feel the decrease in power. Good thing to get fixed IMHO.

Another vote for the fan clutch

Well... Just got the fan Clutch changed and sound is still there :S I know for sure that the fan is turning with the rpms of the truck which is what makes the whooshing sound, so I'm wondering that if the fan Clutch is good maybe there's a sensor or something making the fan activate instead of just staying on idle? Not sure how this all really works but I know the temp on the truck is perfectly fine, it stays right before half like is always has and like every other Yukon.

Does it change any after it warms up? When I installed my new fan clutch, it would sound like a semi taking off from a dead stop, it really pulled some air, until the engine was warmed up and it quieted down. Seems opposite of what it was supposed to do but it works. The fan clutch itself it just temperature regulated, there is no sensor for it specifically. The pcm may increase idle speed for certain conditions. I listened to your video again and thats pretty much exactly how mine sounds with my severe duty fan clutch when its cold.

Take the fan clutch back and get a factory electric fan setup from a later model. It'll fix the sound and free up some power.
