I have this annoying buzzer going off in my car and the "Add coolant" light comes on. My coolant is fine though. I just want to shut this buzzer off. Anyone know how to do that? I noticed that the 75amp fuse under the dash shuts it off when I pull it. What else does that fuse control? Any other way to shut it off?

Also, it's an '86 GXL n/a

Find the sensor on top of the radiator. Either replace it for 10 bucks, or unplug the wire leading to it, and ground it.

I would replace it. You need to know the level of the coolant. Yeah, $10. Not too bad.

That buzzer may be annoying, but that’s the whole point. It’s telling you the radiator is low on coolant (not the overflow tank), and it’s important you fill it immediately. Well that’s a 7.5A fuse, not 75A, and it powers a lot of other things. Leave it in. Do not disable the buzzer, it’s an important safety feature that might save your engine. Fix the problem instead.

hmmm so when you ground the sensor on the rad. the buzer will stop but will the add coolant light still come on?

Felix Wankel

No. The light will stay out.

Please spend the few dollars it takes to fix it right.

My 87 GXl N/A Fc does the same damn thing with te coolant light

ACTION RT

yep my coolant is full as well and mine goes off when the car gets to operating temp.

I started it up the other day(not currently driving it) and the buzzer came on instantly then shut off after 10seconds.

my temp needle stays at the operating temp all the time, even if i get the revs up. also i got out of the car and found coolant kind of substance dripping off the one of the bolts underneath the front bumper. couldn't find a broken hose//leaking hose though. Just flushed my coolant system and cleaned it all out a week ago.

So where is this little bit of coolant coming from, and what piece do i order from mazda to replace the little wire thing on the rad?
thanks

Check your overflow. Thats about the only thing I can think of that will get coolant that far frontwards.
