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
The coolant expands when heated, contracts when cool. The coolant reservoir gives the coolant a place to come and go as needed.
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.
The car is overheating. Possibly the thermostat is stuck closed. Have it checked by a mechanic.
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.
in carry out the answer does not effect but with the overflow the answer come wrong.overflow come due to signed numbers and carry come due to unsigned.
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.
In the upper corner of the radiator on the passenger's side there is a bleed screw. Remove it and fill the coolant overflow tank until it comes out here - it helps if you jack up the vehicle on the passenger's side. Then close the screw until it is almost tight. Start the car, and crack open the screw until it stops spitting out the vent on the side facing toward the headlight. (Get a rag or something to deflect the coolant down and away from the headlight.) Once the bubbles are out, snug the screw down. Run the engine until the cooling fans cycle - if they don't, that could be your overheating problem. It takes several cycles of running the engine until the cooling fans come on, then shutting it off until cold, for the coolant level to stabilize in the coolant overflow tank.
Sounds to me like the heater core is leaking coolant.
Check out the coolant temperature sensor. It could be sending out range signals to the computer. If it is sending a coolant too hot signal the engine will not start.
