Hi, My low coolant buzzer is constantly buzzing. I looked at the sensor and the wire is cut, and I cant tell what harness its suppose to be hooked into. I have looked all over the front of the car, and I just cant find the wire at any harnesses. Any help would be appreciated!! Thanks

 

The wire comes out of the engine harness and may have fallen down in front of the radiator where you cant see it. On my S4 harness it was an orange wire with brown stripes. Hope that helps!!

 

the whole front of the engine compartment is a huge mouse nest... Literally, there has to be 6000 mouse ***** under the hood... I will try to sort through the mouse **** and find the wire. Thanks a bunch!!

 

They probably chewed through the wire.

The buzzer works on ground, if it "sees" ground (in this case through conductivity of the coolant) it does not buzz... so if they chewed through the wire, it would not "see" ground through the sensor in the coolant.

 

i dug around in there and cant find the wire... The buzzin is drivin me nuts!

 

It's a single brown wire that snakes down the passenger side along the radiator support.
It connects with the rest of the (engine?) harness down in the front corner behind the passenger side headlight.
It sometimes has a black or dark gray "sheath" on it for protection from radiator heat.

Thanks Ted, I will look again for this wire.

 

Dosnt it come out a wire bundle under the intake?, if so you might want to cut open that bundle. BTW my coolant wire is black.

 

I found the wire... Its brown with little blue stripes on it. It was in the harness behind the bumper. It broke off IN the harness, so it couldnt be found without cutting the harness open. Thanks!!
