2010 Chevy Aveo LT 1.6 engine coolant leaking Sign In

My coolant reservoir leaks coolant in the area of the coolant reservoir. The coolant boils and steams and the coolant looks like it's boiling over from the reservoir itself. The car is not over heating, however it does go to the middle of the temperature gauge when I drive not too far from my house. I have replaced the thermostat housing and the water pump. I'm in the works of replacing the reservoir and the O2 sensor. The leaking is what gets me the most, the leak is always in the area of the coolant reservoir and no where else. It could be from the coolant boiling over, but I'm hoping after I replace the reservoir and the O2 sensor that my engine light would go off. Today, I just thought about the over head hose; any thoughts on how to check if the hose is going bad. But I don't know for sure, I wonder if anyone else has had this type of problem. I'm due for an emission and with that light on; I know it's an automatic fail. I don't want to spend no more money than I have to. Please help. Thank you

  We would use a coolant system pressure tester- this allows the system to be pressurized - eng off and cool makes looking for the leak easier.
Have you looked at the possibility of a head gasket failure, coolant boils and steams BUT car is NOT overheating - coolant in oil or oil in coolant are some signs of failed head gasket.

Why are you changing the Oxygen sensor?
As far as the engine light being on - have the system scanned for codes and post them.

Hi,
I did check and there's no oil in the coolant or coolant in the oil. I can try the pressure checker when the car is cool and hopefully a leak will unveil itself. I can also look into changing the head gasket. When the car is hooked to an engine tester from advance auto it shows a Bank 1 code, which keeps going towards the O2 sensor for some reason.

The code NEVER suggests a part is bad - it indicates the information seen on that system -o2 ssensor- is not normal.

Hi,
I'm back, it's highschool homecoming week, had me busy.
The code that's showing is P0171 Bank 1 system to lean. I will change the O2 sensor and hope this helps and the engine light goes off. I will be changing that part soon in a couple of weeks.

No, that does not mean that you have a bad 0/2 sensor. It means that the 0/2 sensor is reporting a lean mixture. That usually means just what it states, that the system is too lean for some reason and that is what you have to find. Check it carefully for any vacuum leaks or leaks in the intake snorkel. In rare instances it can be that the sensor is incapable of reading rich but usually not.
