There is what seems to be a sensor on the top of my radiator, smack dab in the middle of the top. It's black and made out of some kind of plastic. It also has a connection wire running from it.

I was just wondering what it was called because it broke on me. And now my coolant light is constantly on...along with a constant "beeeeeeeeeeep"!! Oh, and if possible, a place where I could buy one. I've taken it to the local parts stores (HiLo, AutoZone, etc.) and none of them have it.

Thanks.

 

Mazda factory part - called a Coolant Level Sensor. The warning buzzer that you're getting is due to the 'Oscillator' working correctly in your car. Be proud; most of our oscillator circuits don't work anymore, so we don't have the benefit of an audible warning re: coolant level.

Mazdatrix has this part, Mazda # 15-610B-8553 @ $36.41;


Local parts houses may have it - BAP might. HTH,

Oh, yeah - here's a link for you: http://www.mazdatrix.com/b8.htm (near the bottom)

 

That's the coolant temperture sensor, Victoria British has it for thirty bucks, better off going to a junk yard if there's one nearby.

 

oops, right coolant level sensor

 

That's it!! Coolant Level Sensor, huh? Thanks Duck. I'm going to the link in 3,...2,...1,...**poof**

 

You could also just ground the sensor wire. that'll take car of it.

 

Yep,... I should have mentioned that.

As stated above, if you ground out the tag end of the lead going to the coolant level sensor, it will turn the buzzer off at least until you get the new sensor installed. I would check the coolant level often, however, and replace that sensor, just so that you don't overlook a problem that could lead to overheating (rotary death).

Good catch, Feds!
