Want to be sure I am not alone on this.

Do all 07's have that loud secondary fan going? Damn this is loud as hell.

 

[Rollin Thunder]

you mean the exterior fan for the radiator. Mine is loud when ever im outside (sounds like a damn jet) but in the truck its barely noticeable. Also it only happens on very hot days at idle when not moving.

Yea, it happens when its hot and I don't hear it at all when I am inside. I love the way I can't hear the engine when I am in the cab. I love 07 series!!!

 

[TAHOE FREAK]

Yeah it can get noisy, but I don't mind as other cars get loud as well.

 

[Shaggy]

I don't mind it at all, if its a normal thing for all 07 tahoes.

 

[preston]

Yeah, I get it too when its hot out or been idling a while. Not really noticeable from in the vehicle unless your trying to listen for it.

 

[Timmay]

Guess I never really noticed it inside my 07 Denali. It is supposed to have a real quiet cab, so I guess GM got that right! I do love this truck though!!!

 

[07SuburbanLTZ]

I have never noticed it myself. I'll be sure to listen for it today.

Only when it's really hot out.... given you live in AZ Shaggy....I can only assume it will kick in quite a bit....That or you're really old and paranoid when you hear a noise when this is really nothing

They started using the Efans in 05 they can be noisy when they kick on.

I have never notice it. But it has not been hot yet. I do notice the noise they make while in the garage after I turn off the motor. The spin down is rather noisy. My Impala is also noisy...

 

[Scotto2323]

I notice mine when I remote start and the A/C is on.

 

[nc6600]

I have noticed it. I guess its normal since so many have heard it.

 

[Rollin Thunder]

I heard mine turn off today for once. amazing how much quieter it is with out the fan on. lol.
