Chrysler Repair: Car overheating and losing coolant., 1996 chrysler concorde, losing coolant

Question
QUESTION: My 1996 chrysler concorde was overheating two days ago. With the help of a neighborhood mechanic we noted that the engine oil level was very low. We topped up with engine oil and the engine temperature reading was back to normal - midway between hot and cold.  Today the engine temperature reading was indicating "hot" again, after about a half an hour of highway driving. I checked the engine oil level, which was fine. Upon inspection of the coolant container, I noticed that it was empty, which was strange because two days prior the container had sufficient coolant. I filled the container with coolant to the appropriate level, and then let the car idle for about two minutes, and thereafter revved steadily at 3000 rpm for about 3-5 mins. The temp indicator started heading towards "hot" again. From the driver's seat I noticed a smoky haze coming from the coolant area. When I checked, I noticed coolant flowing from a second hose, which is about 12" in length, one end of which is attached to the top/neck area of the coolant container. The other end of this tubing is free. Is this tube supposed to be unattached or open? Is a clamp device missing? I noticed an "indentation" in the container that is just about the same diameter of the tubing...does the free end of the tubing go into that indentation?       Thanks in advance for any assistance you experts can give.

ANSWER: I dont know about the tube location unless i see a pic of it. Depends on what engine size u have as well.

QUESTION: The engine size is 3.3 Liters/Chrysler Concorde. The overflow tube is attatched at one end to the top of the container and is 3/4inches in diameter, and about 12inches long. Any car parts company with a website should have a picture of what I'm referring to.
The problem is that coolant was overflowing from this tube, which is probably what is supposed to happen.  My question is what is causing the overflow? Do you think the coolant system needs to be bled?


Answer
is the cap for the coolant there??  if so  then its an over flow tube   it would be over heating and the hot coolant needs to go some where  so it goes out there   now on to the real prob   is the fans on?  does it over heat while driving    only at idle    more info.
