Firefighterf: not knowing exactly what engine of the three you could have in your car: 3.5, 3.9 and 5.3, I could only study up on technical service bulletins and recall some of the cars i have had in my shop with cooling system problems.
GM used "DEXCOOL" antifreeze which had a problem that caused corrosion and reeked havoc with the cooling systems on many of the vehicles they used it in. There was a service bulletin out on this matter to address a procedure in flushing the systems. There were quite a few cars which needed radiators, water pumps and heater cores replaced from the corrosive damage done by the DEXCOOL.
Check your car and make sure that you have not got a situation pending where the cooling system is fixing to leave you stranded or burn your engine up.
The V-8's didn't really have any problems with cooling systems which were mentioned in service bulletins other than that one.
The 3.9 liter had a problem with head gaskets leaking coolant. The leaks would appear to be coming from the top end(s) of the cylinder head(s), leaving small deposits of coolant on the ground after sitting. A new gasket design came out to resolve the problem.
The 3.5 had a problem with head gaskets as well and additionally a problem with leaking "crossover " pipe gaskets.
Add this to the issue with the corrosion problem of the DEXCOOL and you have a serious situation. Keep in mind, that often people open the radiators or cooling system recovery tanks when they might still have some pressure in them. Coolant spills or sprays around the immediate area, including near the "FAN GROUND LEADS". If you end up with poor grounds, you will develop problems with any electrical components which rely on those ground circuits. NOW! Here is some more food for thought that few techs have ever told customers. A coolant temperature sensor is designed to be immersed in coolant or water. The heat transferred from the water or coolant to the temp sensor, causes the sensor to change resistance values which in turn, will make relays go on an off, give input to the ecm for it to use as part of the data needed to control pulse width of the injectors, and guages indicate the temperature. One phenomenon that occurs when the coolant level drops to where it no longer has the coolant sensor immersed, is that the sensor will no longer read correctly. You temperature guage in you dash may indicate the engine is at normal operating temperature and the engine may be in thermal nuclear melt down!
Steam in the cooling system will not have the same effect make the sensor register hot!
I hope that I may have given you some direction in which to look.
My not knowing the particulars, I tried to cover as many bases as I could other than dealing with relays, fuses and wiring. I would need the specifics on YOUR car to be able to better assist you.

SOURCE: Problem with 2006 Chevrolet Impala --Windshield washer fluid

Sounds like the fuse blew out again. Look at the wiring that goes to the washer fluid pump and check for any place where it might have rubbed against something causing it to short out. Fix this 'short' before you replace the fuse again or you will continue to have problems.

How is the a/c condenser attached to the radiator on a 2006 impala

According to Mitchell On Demand, you need to remove the radiator first. Remove cooling fan assembly and then the radiator. The condenser just rests on the radiator mounts with 4 mounting pads. You lift the condenser off these to just replace the radiator leaving the condenser in place. Of course after removing the radiator, you disconnect the condenser lines and remove it at that time.

Car overheating with full radiator

Check cooling fans when engine is hot. If they are not running check temp. switch to fans and fan motors. If they are running you probably have a stuck thermostat.

2002 impala 3.8. Overheated. Had coolant leak.Replaced bad coolant elbows and thermostat with fail-safe. Car still overheats. Noticed cooling fans not running when A/C turned on. Blown fuses. Replaced....

A bad relay will not blow a fuse. The radiator cooling fan must run with the A/C on or the vehicle will overheat and the A/C will perform poorly. First I would check the draw on you cooling fan motor-it may be blowing the fuse, or you have a wire shorted to ground.

Engine hot a/c off on 2006 impala any suggestions

check cooling fan fuse, a quick way to check, turn on your A/C while the car is running, the cooling fans should come on right away, if not try a direct wire from the battery to the fan plug, that will tell you if you fan motor or motor's are bad.

I have a 2006 Chevy Impala LT 3.5 L, and if I drive the car, the fan under the hood remains on, even after the car has been shut off and the key has been taken out. It stays on for about 2 minutes, then...

It's suppose to. The fan will continue to run after the car is shut down to cool the radiator down before a timer shuts off the fan. I also own an '06 Impala LT with 69000 miles, and the coolant has been "disappearing" Since there isn't any excess water coming from the tailpipe, I'm figuring it's the water pump, due to the noises it makes (think marbles in a beer can). Be safe and check you coolant level. Hope this helps you!
