coolant buzzing sound - HELP
 

i just had a motor installed into my S4 turbo2 and the coolant level is full with no air pockets and the buzzer goes off after about 1-2 minutes after started and stays on the entire time. its really annoying and i dont know if its just the wire or sensor for the coolant level is disconnected or bad.

can anyone tell me where to check for the wire connection that may just need connected or grounded. i thought it was the wire coming off the radiator in the center top, but then again this radiator came from an automatic.

any help or advise would be appreciated, thanks.

car is a 87 turbo2.

the sensor is in the top and middle of the radiator. it has a single wire running to it from the pass. side. (brown i think). if the sensor is bad (or missing) this wire can be grounded to the body to make the buzzer quit.
