Just started to get a humming noise in my car in the morning. The engine was sounding kind of loud in the morning for a couple of days, but was quite by the time I got to work.. so I forgot. Today is the 3rd day. Now its loud and noticeable. I only had a few minutes to look under the hood before I had to leave town for the weekend in my SUV. As best as I could tell in about 5 minutes was that one of the two electric fans on the radiator is vibrating. When I get back I plan on disconnecting the electric lead to each to see if I can isolate it to the fans, then to which fan.

Before I do this when I get home, Im curious if anyone has had a similar buzz, noise vibration from those fans. If so, was it the fan, or was it a clutch? Is it possible to change those fans without removing the radiator?

Of course, my car just got back from the shop about 500 miles ago. Just had the 90k tune up. New timing belt, water pump, spark plugs, etc. Also had a minor leak from the cam covers, so those got replaced too. Spent over $1k. There is nothing like going back to the shop after having so much work done.

Thanks

Lately I've noticed the fans are really loud too. Is this normal? If I turn my car on ( not starting the engine) I can hear the fans start spinning.

It's a V8 so fans need to be strong to cool the engine.

As for the humming, I would check the fan's rotation if it's wobbling.

Oops! Didn't realize that this was the SC forum. I drive an IS350. I'm assuming that I should still check my fan because to me it seems like it is excessively loud.
