is there anyway to disable that annoying buzzer?!?!?! my coolant isnt low, it was just flushed, and its filled with water wetter and a little bit of coolant, the rest distilled water. for some reason it still keeps coming on! it just comes on randomly. is there anyway to disable that GD buzzer until i can fix the problem????

 

uhh are u sure its not your oil that is buzzing. maybe you are leaking coolant and your coolant is actually leaking or your sensor wire is breaking off on top of the rad. i wouldnt just rip the buzzer out but if you really want to its on the back of the gauge cluster. they are very sensative to low lelvel in the coolant and oil. i would check both. because if it starts buzzing around turns your probley low on oil

 

check the wire on the coolent sensor, mine came off and the buzzer went crazy.

 

just ground it.....but make sure to always keep ur coolant filled

 

this is covered in the archrives.......

Bad, bad, bad advice!

The warning is there for a very good reason. Rotaries don't tolerate being overheated and if you have a sudden coolant loss (burst hose, cracked radiator) this warning will tell you something's wrong well before the temp gauge does. It could literally save your engine (and your wallet).

If the warning goes off even when the radiator (not the overflow bottle) is completely full and the cooling system is properly bled of air, then it's probably an electrical problem. The simple procedure for testing the system is in the FSM Body Electrical chapter.

 

i know for a fact its the coolant system, i work at jiffy lube and i sure as hell know its not an oil problem, i have no problem keeping oil in it. i checked it when it 1st started going off and the oil is clean and full. as far as the coolant, after further research around the forums, im thinking its air/bubbles in the system. it didnt start going crazy until i did the flush on it. im gonna drain it all out and refill it tomorrow at work. the radiator and sensor wire are all new, but i think the connection from the wire to the sensor may be bad. it looks like it might need to be soldered or re-done, ill check that after i refill it and see if the problem persists

 

the add coolant buzzer saved my engine when the hose from the heatercore decided to give my engine a steamcleaning. I hate the sound but I love the function

As it goes of random just check all the connections, often enough its electrical.

 

I would NOT brag that you work at jiffylube!!!!!!

J/K The coolant level sender is a POS. If you get a new one here's a tip......add heat shrink over the wire where it starts at the sender.

 

That and make sure your **** isn't broken. Also aftermarket temp gauges work as long as you keep an eye on em. I grounded my sensor wire but then again I don't have any leaks and replaced all my hoses, radiator, and thermostat. But then again the more annoying the buzzer is the less likely you are going to fry your motor due to negligence.

 

My buzzer was doing the same thing, so I performed an "abortion" on it. I honestly don't care that I don't have the buzzer, simply because the 'coolant' light still comes on in the idiot cluster and I've got an aftermarket coolant temp. gauge that I check constantly when driving. To "abort" the buzzer (if you so desire). Remove the gauge cluster (kind of a challenge if you've never done it before) and flip the cluster on it's back... You'll see a bunch of electrical circuitry etc., but look on the bottom and you'll see a little white 'speaker' that's imbedded in the circuitry.

Take a drill and perform the abortion. It's actually quite satisfying.

 

That even stupider than grounding the coolant sensor. Now you have no coolant level, oil level or redline warning.

Those who say they watch there gauges "all the time" are deluding themselves into a false sense of security (how you you manage to stay on the road?). If you have a sudden coolant or oil loss the warning buzzer will tell you something's wrong instantly, not the next time you happen to look at the gauges.

 

Nooo... I think you're over-emphasising the importance of the buzzer.

Uhh... Actually I do have coolant-level, it's in the form of a BRIGHT RED LIGHT on my idiot-lights. As is low oil...

For redline, I don't need a buzzer when I have a large tach lit up in front of my face and a pair of ears that's in tune with the RPM that my motor's spinning at... Frankly, I'm not a fan of the buzzer. You are!

 

Not uncommon to have the light not work, when the buzzer does.

Of course the Buzzer also tells you of low oil level, besides low coolant and over rev.

Disabling the buzzer is pretty stupied in my book (and as you can see; in many others opinions as well).

Fix the car

 

Well... Every time I've ever had the low-oil or low coolant buzzer go on, their respective idiot light has came on as well. It's like, FLASH, BUZZ! Except, I hate the buzzer and I don't mind the light...

Frankly, I'm not worried. It is (of course) better to recommend being overly cautious, as opposed to removing one method of warning, but is it that big of a deal?

The low-coolant light works in perfect unison with the buzzer, and it has in all 4 of the FC's that I've owned. The light is very bright and is paired with both the stock coolant-temp gauge in front of my face, and an aftermarket gauge under the logicon controls, which is also well lit. The temp. is always at a rock-solid 180F when cruising and I habitually check it about every 30 seconds or so--just a glance.

Not to mention that I have brand-new OEM radiator and heater-core hoses... The BAC/TB/thermowax hoses will also be disabled within the week (even though they've been replaced as well).

Regarding oil "precautions"; I have the bright "idiot" light, the stock oil-pressure gauge and an aftermarket oil-pressure gauge. Both are well lit and both are easy to read. Shoot, I've even got all S/S oil-lines (cooler and OMP)... So no cracked OMP lines or blown oil-cooler lines for a while.

My life without the buzzer is just fine. Not only that, I've got a new PD as well. woot!

But yes, continue to rain on my parade of n00b'ish idealism. I realize that you both are on solid ground, wheras my 'lack of buzzer', puts me on like, 80% solid ground... Yup.

 

but this would be an example of a responsible rotary owner and you have the tools to check your cars condition even if your primary instruments fail. very different from the poster

 

Heh... Well, since "stupid" was the adjective of choice by both NZ and Icemark regarding my buzzer delete, (which I never recommended), I felt obligated to explain my position fully.

 

IMO the importance of the buzzer can't be emphasised enough.

Bright red light my ***. The warning lights are small and not all that bright. In sunlight they're easily missed. Don't you ever drive in bright sunlight?

 

No...
