when your engine is hot it causes the water to boil and the water and the anti freeze will come out of the overflow pipe.
The coolant expands when heated, contracts when cool. The coolant reservoir gives the coolant a place to come and go as needed.
Low coolant level.
It sounds like you have a bad head gasket.
If you were to overfill the coolant in your car, then it would start to overflow and come out of the car. The most damage that this would probably do would be getting the coolant on the ground and wasting it.?æ
Check your overflow bottle to make sure there is adequate coolant in there. If there is, the coolant level sensor is faulty and must be replaced.
The "check coolant level" message will come on when the coolant level is low in the overflow tank. If the message stays on after the tank is filled, make sure the sensor on the front bottom is connected. If the connection is O.K., then lightly tap on the side of the overflow tank with a soft rubber mallet. If the message persists after driving the car a couple of days, replace the overflow tank.

Check to coolant level in the coolant recovery tank and radiator when engine is cold
Remove all the connections going to the ECM carefully. Remove the 3 bolts that hold the ECM in, remove the ECM. Take the coolant overflow tank out. There is a stud that held the coolant overflow bottle in at the back, remove this by prying it from inside the wheel well. The fan will come out easy after all this is removed.
