How to disable "add coolant" buzzer
 

Hey everyone!

My coolant level is high and everything, and I've found a minor leak. The thing is, I'll just keep filling up the coolant every few months or so, because the leak isn't that bad. I believe the cold weather is affecting me "Add Coolant" warning buzzer, because when I start the FC up in the morning, the buzzer will drive my nuts for about 20 minutes until the heater has warmed up nice and toasty. After it's warm, then the really annoying buzz will stop. I will try to find the problem, but for now, please help me disable the buzz. It's been driving me nuts (and my passengers) since the cold weather came!

Any specific directions or wires I need to cut?

Thanks everyone.

bad idea. Disable the buzzer = Forgetting to check the coolant level = Blown engine...

Fix the leak and you fix the problem.

The buzzer is there for a reason. IE: Protect the engine! The stupid thing to do is to disable it.

I KNOW that Jim Carry at one point owned a Second gen before he made "Dumb and Dumber"..... Because in the scene where he makes "The Most Annoying Sound in the World"..... its the exact same noise that the freaking Add Coolant buzzer makes in my car!!!!!!

Look for the wire that goes to the sensor (top of radiator) and ground it to the chassis. I had to do this when I replaced my radiator with a gigantic 29x20 double pass howe radiator. I have a real temp gauge and check the fluid often, you might want to consider the same.

Do not disable the warning. If a hose blows or something, you won't know. This buzzer has saved many an engine when the drivers side heater hose blew.

just make sure the sensor is grounded, thats the problem 9 times out of 10. without the right connection it will always go off...this sensor has saved my motor as well, I was leaking coolant from my radiator and even though temps were normal the buzzer went off bc the coolant was low - got a new rad and saved my engine from potential overheating :)

I entirely 100% stand behind Aaron Cake, do not disable it.

But if you are dumb enough to disregard this, you can simply disable the sensor by cutting it off at the wire, (I would reccomend leaving the wire harness in place)crimping on an metal ring connector and screwing it down to a ground point (engine, chassis, etc).

If you want the light to still work, but disable the buzzer, you would have to cut off the buzzer entirely, which (according to the wiring diagrams) is wired with the oil level sensor and the tach. It's somewhere behind the dash, sorry I don't know what color wire :(

I agree with everyone. That's really a BAD idea with possibility of horrific results.

disable noise, but not warning light?
 

How can I disable the noise, but not the warning light?

I will definitely not totally disable it, but is there a temporary solution?

How do I ground the sensor? Where is it at?


Thanks again.

Since this seems to be a faulty sensor, unplugging the sensor's wire and grounding it will stop the buzzer sounding unnecessarily. Make sure to replace the sensor ASAP. As mentioned, this could save you from a very expensive meltdown.

The buzzer also warns of low oil and redline, so it shouldn't be disabled. Aural warnings are much more effective than visual ones, so don't rely on just the warning lights.
