Check your oil level.

Also, make sure the cooling system is properly bled. Air bubbles around the sensor can cause the buzzer to sound.

 

i just got an oil change last week. i checked my oil last night and it reads good, but do you think i should get a radiator flush?

 

this might be out of line, but you said this is your first car. You said you checked the overflow tank, but did you actually take off both of the radiator caps and check the fluid in that?

 

wire going to the coolant sensor.

 

Please do not bump your topic, especially after only 30 minutes.

Make sure the cooling system is properly bled. As I mentioned, air bubbles will cause the sensor to detect a low coolant situation. Also, as snowball mentioned, check the wire at the coolant sensor on top of the rad. If it is disconnected, the buzzer will sound.

But it sounds like you just have air bubbles.
