Coolant Buzzing, Need Silence.

I have a new main wiring harness and a new water level sensor. I grounded the water level sensor wire to test, and it still buzzes. I have disconnected the oil level sensor, and it still buzzes. What am I missing here? It never stops buzzing.

I have read through many postings about this, and I have come to one conclusion. Unless I am missing a step, the results indicate a broken wire on my water level sensor somewhere in the harness, or something might not be grounded properly. Can anyone tell me where the water level sensor wire connects to in the car, so I can attempt to ground it farther up the harness, to see if a broken wire is the problem?

My coolant light stays on continuously and so does the buzzer.

Temp never exceeds 85C. Oil level & pressure are good.

Any suggestions?

Thanks in advance.

The water level sensor can be run directly to the wire connectors by the diagnostics box and battery. The wire is brown/white I believe, if you need me to I can take a picture of where I ran mine recently when I rewired my car.

I have no idea how to fix the problem. but the sound of the coolant buzzer is the most annoying sound that I have ever heard. It will drive you insane if you dont fix it real soon!

Theres two connectors for the water level sensor:
1) where it connects to the sensor by the filler
2) Theres another one behind the a/c compressor area,single wire
black connectors.some people miss this one and the buzzer just keeps going doesn't matter if you ground the other end.

Is this wire, one behind the a/c compressor area single wire, from the main harness? Where does it connect to?

If you can't find the single wire, I just told you where it actually can be run directly. The harness connector by the diagnostic box on the battery side, it has a brown/white wire. Run it directly to there and splice it in = no more buzzer unless your coolant is really low.

I found it! The Brown/White wire connects into the main harness to a black connector. I Plugged it in and no more buzzing! It works!

Thank you everyone!

PS. I just passed 500 miles on new www.BNRturbos.com motor, it still running! Time to change the oil!

I just had the same problem and the fix was:

Look behind the AC compressor. There should be two sets of connectors.
One set of black connectors for the water-level-senor and
one set of white connectors for something else

When i put the engine in after porting i for some unknown reason hooked one black connector(the one comming from water-level-senor) with the white connector.
And that damn buzzer never stoped.

I at one time removed the elbow and stuff "ontop-behind" the AC compressor and looked down with a flash light. I did not see then that there where to loose connectors.
The wireharness and a cupple of AC lines where in the way.
Since i forgot that there was 2 set of connectors i didnt think more about it.

Then i got F*n pissed off at the buzzer and i went at it again.
Removed the elbow and suff and this time put my hand down to see if any wires where loose and imagine my supprise when i after a while had a non hooked up connector on the top of my fingertips.
Pulled forward my flashlight and started to try to get the connector to a place i cood look at that color the wire was. Then i saw the other connecor!
"hmm one black and one white connector loose and not connected to anything at all"
"Why is that black water-level-senor connecor connected to a white connctor when i apparently have a loose nonconneced black connector left????"

Just hooked those too connector set up correctly (black-black and white-white) and everything was fine!

now im just thinking of maybe doing a "poor-mans non-seq" and a tuning session at some rototest facility
