What in the hell is this buzzing coming from? Help!
 

My car is LS1 swapped, but please do not move this to other engine conversion sections because that has nothing to do with this annoying buzzer. The cooling fan light is on, and the buzzer goes off all of the time. So my questions is how do I disconnect this light/buzzing noise?

For the buzzer, you probably have the low coolant sensor not mounted or hooked up.

For the light you probably have some screwed up wiring...what did you do with the ECU and engine harness?

And both these are not really realted to anything but your swap, so this really does belong in other engine conversions

So yeah, thats fine, but how I get rid of the buzzer? Where is the low coolant sensor? I don't care too much about the light, but damn this buzzer.

What are you using for a radiator??? The sensor should be touching the coolant.
