#18 of 22 Fan noise when I turn off my car... by nklemann Sep 27, 2007 (4:04 pm)
Recently, about 5 seconds after I turn off my car, there is a noise that comes from the front. It sounds like a fan swooshing to a stop. Only lasts about 1 to 2 seconds and isnt very loud. Any ideas? Replies to this message: rstraub (Sep 27, 2007 4:31 pm)

Replying to: nklemann (Sep 27, 2007 4:04 pm) We had the same fan noise. What was happening with ours was it was running hotter than norm. I flushed it SIX times before it flowed properly without replacing the radiator. Anyhow, the fan was making noise due to it having dry bearings in the fan motor. WD 40 repeatedly took care of that, make sure it's cool and off when you do this. once you get it flowing properly it shouldn't come on hardly at all. for a bottom feeder car ( no big grill for air flow )they run pretty cool. As for the sensor locations, call a dealer and ask to speak with a tech. or just go to an auto parts store and get the repair manual. Good luck, Rich

#22 of 22 Chevy Impala by bdeihl570 Oct 05, 2009 (8:28 am)
I have a 2005 Chevy Impala, and when I go to take off, I hear what sounds like water sloshing. It sounds like it is behind the glove compartment. I don't know if it is water in some sort of drain pan that won't drain or what. Does anyone know what this might be and how I could stop it? Thank you in advance!!
