Question Coolant level sensor leaking.

I guess its the coolant level sensor. On top of the radiator right in the middle. Yeah well mines leaking. it not cuz its not tight enough though. Do they sell these at autozone? If so how much?

Victoria British sells them, I don't think they are that costly. And it wouldn't hurt to call Autozone or where ever to verify if they carry the part.

Yeah, 16.95 at VB. Part # 71-618

Yeah, I sacrificed my oil pressure sender for the turbo oil feed, didn't need to, but the sender didn't work right anyway and it was an excuse to not get a new one But even I wouldn't go without the coolant temp.

Why not? Do you test yours regularly? So how do you know it even works? Oh cause it never had to......


I pop my hood everytime I put in fuel and watch my gauges when I drive. I also look under my car when I park and prior to getting in.
Secondly I service my car regularly replacing parts like belts and hoses annual when I flush the cooling system. I replace the radiator every 5 years.

That little sensor springs leaks, could fail when you really need it. I believe Mazda put it in because of the lazy people that buy cars and never take car of them. If it was so important to have it install, don't you think Mazda would have done something more drastic that turn on a dash light and ring a chime?

That has to be one of the most retarted posts I've seen in a while.

What if the thermostat goes bad, or you get a faulty one? What if a hose busts while driving? Sure, it'll probably never happen and you'll probably never have anything go wrong, but I'll be laughing my *** off if it does. There's no reason to not have the temp sensor.

What the **** do you want Mazda to do to let you know it's a good idea to have it there? Honk the horn? Maybe give you an electric shock?

****, I run my car without oil. I think if it was so important for it to be there, Mazda would have done something more drastic than turn on a dash light and make a buzzer go off.

No, that sensor is for the coolant temperature gauge, the sensor on top of the radiator is for coolant level.

THE TOPIC IS ON "LOW COOLANT" sensor, and that is what I am commenting on. It is mounted on top of the radiator, and it purpose is to turn on a dash light that says "low coolant".

My reply was to plug off a leaking low coolant temperature sensor. I never said or recommended removing the coolant temperature gauge.

Before you say something bad about another post, make sure you READ IT.

The stock location for the coolant sensor is located on the drivers side of the engine. The semi-automatic choke sensor is located in the back of the water pump housing.

First hand experience. I grounded the LEVEL sensor on the rad. Just so I wouldnt see the warning light on the Inst. Panl. (temp i was getting one the next day.) anyways I noticed the Temp slowly getting hotter. Then didn't pay attention to it cuz I ASSumed that It was full cuz I did check it prior leaving to work. I figured it was just cuz I was pushing it. Soooo, I pop the hood and there it was I was leaking coolant (flowing) from where I plugged up the heater pipe. After fixing the leak, I filled up the system almost 3/4 for sure more than 1/2.

So in that case as soon and the level was low (I think even 1/8) I would have know that was the problem and STOPPED instead of pushing it the extra 1mi left that I had to get to work...

Like that Cody...

Yes, the coolant temp sender is located on the rear iron, under the oil pedistl.

Thanks for the info guys,but i already know all this. Im not a N00b. lol What i needed to know in the first place was where to get the L_E_V_E_L sensor or a plug that will fit into the top of the radiator. the threads on it are weird. i couldnt find a match. BUT i got the sensor to quit leaking.

I have an aftermarket temp gauge and its hard to find fittings for the original location so thats why its in the waterpump

Thanks for the help

Um, you didn't read my second post did you? heh...it's right there. Victoria British sells them. It goes in the top of the rad, it's cheap and everyone should have one. Anyone who says to get rid of it, is insane. I check my fluids every week, my car is like my first child. I keep good care of it as much as I can. But you never know what might go wrong while driving around or maybe sometime in between your checks something goes faulty and throws a temper tantrum.

I know I'm not exactly answering the question, but have you tried replacing the gasket, then properly torquing it? (to a whopping 13 to 21 INCH pounds)

I did this, but I think the soldered-in threaded boss actually might be leaking

And thus you buy a new one....for a small fee.
