i started my fd after changing the plugs and my coolant buzzer started going off. i shut it off and checked the coolant and it was kinda low. i topped it off and started it up again and it kept going off. i shut it off again and it was completly full. i warmed it up, took it for a short drive, and the buzzer was still going off. i let it cool down and checked it and guess what. still full. any ideas what might cause this. when it warmes up tomorrow i will look for a broken wire. i already took a look at the wire directly out of the sensor and it was fine. i'll take a better look tomorrow. any help would be great.
