Could be any number of things. You might check the radiator and make sure it isn't clogged up with dirt or debris on the outside (maybe a plastic bag of something has gotten stuck on it). Then maybe check the inside of the radiator to make sure it isn't gunked up. Could also be the thermostat (if you haven't replaced it in 155k miles it probably wouldn't hurt to do that just in case).
Only other thing I can think of is we used to have an old Ford Escort, and the controller that regulated the electric cooling fan burned out under the dash. I didn't notice anything wrong with the car until the summer when it would get hot if I got stuck in traffic. Basically as long as the car was moving, there was enough air going through the radiator to keep it cool, but if I stopped for any period of time the car would get hot. So if you notice the car gets hotter when you're sitting still you might have a fan problem.

I think you'll find due to these cars being a "bottom breather", they tend to run a lil warm to start with. Flush your system though. I had to flush ours five times with a coolant system flush before you could actually see it circulate by the radiator cap! You'll find that it not only cleans out the engine but it's a lot cheeper than a new radiator. It runs a lot cooler since then. We are also pushing 170,000 miles as of now. Good luck selling her. The dealer won't give you anything for it even though it's totally loaded. KBB says it's worth $5,000 +, I've only recieved offers of as much as $1,800. It's really hard to part with a car knowing what it's actually worth, and after maintaining it all the time as required and needed. If we could even get 3,000 to almost 4,000 that would be good enough. Well, good luck.

It's a work car, so the resale won't hit me directly. Besides at 155,000 miles I've definitely gotten the goody out of it. In your case, you could drive it another 50,000 or 100,000 and probably get the same money for it, so I'd keep driving if it's still dependable.
That's what I'd normally do with this one, but I've got 3 little kids and the last thing I want is to get stranded in -20 degree weather. I also want the new stability control systems for more safety.

I think we got the cooling issue figured out. I had it in for an oil change and the mechanic said he blew out the radiator with air and a lot of grass came out. I drive through farm fields once in a while so it makes sense. I had blown the front of the radiator out with water earlier in the summer, but evidently the only good way to get to the area involved is to put the car up on a hoist and come in from behind; neither of which I can do at home too well. It seems to be running much cooler now.

Where is the Coolant temperature Sensor?!

HELP!!! I have a 2001 Chevy Impala with 316,127 miles - LOVE my car! I've been having a problem recently. When my temperature gauge doesn't move, my A/C doesn't move. Oh, it blows but doesn't get cold and that is unacceptable living in south Texas!! i read a few forums and learned this could be a coolant temperature sensor problem so I ziggied on over to the nearest auto supply store, bought the sensor, but I'll be darned.....I can't for the life of me figure out where it is! Neither can my husband. If anyone knows, I would be so happy!! I might add that this doesn't happen all the time, when the temperature gauge moves, the air conditioning works great. Thanks a bunch!

Fan noise when I turn off my car...

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?

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

Dirty sensor was my problem. 2000 Impala - Low Coolant light always on. System full. Pulled the sensor and found it was pretty dirty. Washed it off, Q-tipped it, pushed it back in. Good to go. Light is now off.

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!!
