I'm having the same problem, Add coolant lite on normal temps and full of coolant. where is the water level sensor? I thought it was behind the T-stat housing with one wire.

 

do a search - the level sensor is on the *front* side of the thermostat housing.

I did and came accros that thread on my first post which is the same problem I'm having. so I'm thinking i got a bad level sensor

 

i had the same problem and changed my coolant level sensor for $48 from malloy mazda and its back to normal. like said its in the front of the thermostat housing,looks like a black rubber bolt with a wire coming out. simple to fix.

If I grab the wire of the sensor and ground it, should the buzzer stop? I just want to know before i order the sensor because it looks new.

 

yes, if u ground the wire, it should stop, thats how i stopped it with mines

 

then is not the sensor. I got some wiring to fish

 

Did you try grounding it? I would use some carb cleaner and a pipe cleaner and see if you can clean any gunk out of it.

 

I went and ground it and got nothing so I trase the wire after the plug and the wire was broke

 

I had that same issue.. I don't know what I did.. but it stopped.. Damn car!

 

well I fix the wire no more buzzer!!!!
