The whistling noise is steam. The problem is you never attacked the source of the problem. What you need to do now is drain your radiator completely at opening T-spicket at the bottom of the radiator. While you drain with engine off, run your water hose on top, to flush out the radiator. Then run to the Auto store and buy "radiator flush" -- follow directions. After flushing out the radiator flush, close the T-spicket, and fill with NEW anti-freeze. By enough to fill to the very top. Mix the anti-freeze with water per instructions to your environmental weather.
Buy a new radiator cap which could have caused the problem in the first place by not allowing the correct pressure to blow off. Being a 2000 car is a little early for radiator problems, but an incorrect anti-freeze solution causes radiators to fail prematurely.. Better to have more than less because anti-freeze keeps the radiator from corroding.
Your radiator never cooled the water sufficiently, and boiled much of the water out, hence it got so hot that it would melt the water tank. The Thermostat could well have been the cause because it got corroded from the inept ant-freeze mixture. Did you find rust on the Thermostat ? If so it was the case. If not the radiator has lost cooling either by low water or the cores have become plugged up, in that case you will need a new radiator. See if the flush loosens the rust within the cores before buying an expensive radiator. Check the water hoses if leaking cooling. Run the car allow the engine to become hot before accepting that your water hoses are fine. Because heat expand everything, and may not leak until after the expansion.

Wow.....sounds like some one has been guessing!
what is the oil condition?
If you remove the oil filler cap when the engine is idling is there excessive pressure?
any excessive smoke from exhaust?
is the coolant contaminated?
if you run the engine and take the cap off the expansion tank, can you see coolant returning to the tank from the small hose when given a little blip on the throttle?
do let me know pls?
Also, can yo actually see the water pump or is it cambelt driven?

SOURCE: when car is running and fan comes on

Sonds like the fan to me. Yes, those are available separately. Water pump is internal inside of the timing cover and those are pretty bullet proof. Fan is most likely NG. Not that common. I have replaced only 1 in 12 years with Nissan.

pull the spark plugs and look down into the cylinders with a small bright flashlight, if the top of any piston is nice and clean and shiny and the others are not, you have a head gasket leak on that cylinder, it will be very obvious it will look like a brand new piston and the others will have carbon built up and deposits otherwise is your fan operating at all? do you have any heat from the heater? after the car is fully warmed up does the lower radiator hose get hot? please look into these things and get back to me i have seen on these cars many times the fan control circuit fails and the fans do not come on. You can run a ground wire to the fan relay under the hood and put a switch in the car to manually run the fans when it gets hot, i can explain how to do this if your fans are not operating please rate -jeff

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

Concorde overheating

Hi Cheryl, I'm glad to help. This is a hard one to answer because I'm not there to here the noise are see what your engine is doing. My best guess is you may have gotten it hot enough to blow your head gasket. Hopefull you did not get it hot enough that you also cristalized the rings which is bad and hopefully the knocking noise is only because it's misfiring and not a rod knock. You need to have these things checked out. Sorry, for the bad news! Hope this helps and have an awesome day Cheryl.

I just replaced the actuator on my 2000 Chrysler Concorde LXI and my heater still isn't working. Any other idea's?

If its not blowing air then you may want to try a new blower motor if it is blowing air then you probably need a new thermostat

Problem with this is that it could be a number of things, have ur water pump checked, open the radiator and see if there is water running through it, a bad or plugged thermostat, in this case it does sound like a blown head gasket. id suggest flushing the radiator with some cleaner that u can buy at the store and check n see if ur thermostat is stuck, hope for the best and expect the worst
