I had that problem as well, turned out the fan wasnt kicking on because the fuse was hanging out.. However, the radiator is quite tricky on mine. It leaks one day, then is okay the next...

2010 Buick LaCrosse overheated and lost coolant. What type of coolant should be used? Does it just go in to the recovery tank?

You can use any good grade of antifreeze to recharge the sys. Based on how much you have to add to the system you might want to remove the radiator cap and add the antifreeze. Be sure to pour it in slow so you do not get an air lock and spit it all back out when the engine heats up.

Added antifreeze and my 2002 dodge caravan is still overheating....the antifreeze did not move from the reservoir....what could be causing this??!! Help!

When it is cool, take the cap off the radiator. See if you can see antifreeze. If you cannot, pour it directly into the radiator.

Car is losing water and overheating,Where is it going? Is my water pump bad? I have to regularly add water to plastic radiator container.

if you do not see any water leaking ( dripping ) from under the car then I would say that you should start by adding antifreeze to the car and not just water -- if you are just adding water to the 'plastic container ' there is a chance that the car is just boiling off the water that is added, ( since water boils at a lower temperature then antifreeze ). if after the filling the radiator with the proper mix of antifreeze AND water you are still having a over heat issue -- then there is a chance that the thermostat or the water pump is bad and need to be replaced. could also be a cooling fan issue ( make sure the fan is turning ) --- also make sure the radiator is cooling properly. if you think that there is still a leak in the system you can have a repair shop pressure test the cooling system and they will be able to find the leak.
but again --- add antifreeze to the system and see if this helps first. you can buy antifreeze at your local auto parts store,, and since only water has been added - I would drain SOME of the fluid out of the radiator first and top off with 100% antifreeze so you have a good mixture.
I hope this helps ,, if you have further questions about this problem - please write me back here and ask and I will do my best to help.

Engine Coolant Light blinks constantly.

you put transmission fluid in your radiator? You should have antifreeze in your radiator. You could have a bad thermostat that's causing the car to over heat. Does your temp gauge read a high temperature?

99 Firebird still overheating after repairs and antifreeze

overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

Overheated truck

Your radiator is getting clogged up with mud causing the lack of air flow through the radiator. You may want to install a mud deflector in front of your radiator to keep the mud from clogging up the radiator and may be run your antifreeze ratio 40/60 (antifreeze/water) the higher the water content the better the heat transfer, but your have to keep an eye on the level of the coolant level more often. Water will evaporate quicker but too muck antifreeze will have poor heat transfer and 100% antifreeze will gel when heated causing poor circulation causing overheating. Good luck and hope this helps.

2001 blazer - i have changed radiater,heatercore,waterpump and 2 thermostats - still overheating on me? coolant level is fine until it gets hot and boils out overflow tank? help!

Are your antifreeze 50/50 mix. Too much antifreeze ratio will cause over heating, the antifreeze will start to gel when it get's hot causing poor circulation. Water is the best liquid for heat transfer but it will also boil over and steam out the radiator cap, that is why antifreeze is added to keep this from happening. Looks like you have covered most of the base on your cooling system, Did you do a complete cooling system flush to get some of the corrosion out and it's been know for the orange antifreeze when gelled will clog up the cooling system. Make surer you have 50/50 mix and if you not sure you can buy a antifreeze meter at any large parts store like Auto Zone. Keep me posted, be glad to help.
