so all of a sudden my car is making the buzzing noise like the one when your coolant is low but, my coolant is filled and the light doesnt come on it just buzzes and i cant stop it. has anyone had this problem??

Thanks

 

Very low oil???? Check it out. Veeeeerrrrry low oil level.

To PROVE it is not the low coolant level, pull the wire off the sensor on top of the radiator. Hold that wire to ground while the buzzer is going off. As soon as you touch the connector to a ground point, the buzzer should go off, IF it's the low coolant level causing the buzz.
