strange noise
Recently i had some paint work done to my vert. While having it painted i had them paint my FRC's, washer fluid tank, coolant tank and radiator shroud. After i picked up the car i took my wife shopping and on the way home i got a low coolant display, i was only a mile from my house so i went home and as i was backing into the driveway i got the low coolant again and a strange buzzing alarm sound from behind the dash somewhere. This buzzing lasted less then a minute and went away. I looked and it looks like i have enough coolant in the tank, its about 3/4 or more full. I ran the codes and about 34 differant codes came up but they all have an H after them except one that has a H C, it is C2120, i do have aftermarket wheels adn tires and no tire pressure sensors.
Any help would be great....Thank you in advance.
In this pic you can see how much coolant is in the tank and i am still getting the low coolant message
