Just throwing this up so people searching can find it.

I have noticed that my car loses a little coolant every time I drive it (just an ounce or two). Not a big deal, I just top it up now and then.

However, today was different. When I started the car, there was a beeping noise coming from the driver's instrument/steering wheel area. It was not a pattern like

beep... beep... beep...

It was very random. I checked all the guages, and everything looked good, so I decided to drive around the block. As I drove, the beeping sped up the faster I went, but it still wasn't a pattern.

beep..................... beep beep beeeeeeepppppp..................................be eeppp...

very random. The add coolant red light was NOT on. The car was running normal temp. The beeping made me very nervous, so I parked back in the garage and looked under the hood.

The problem was apparent. The coolant level sensor on the front of the water pump body had a pinhole leak that looked like it was coming right out of the wire. This explains the beeping and may explain the very slow loss of coolant I have been having.

Time to get a new coolant level sensor.

 

Yeah looks like the sensor is toasted, time to get a new one. I have like 3 of those so let me know if you need one

 

Pics of the old part. Note the hairline cracks in the plastic thread and the mineralized (is that a word?) look where coolant/water mix was leaking out around the wire area on the front.

New part is in with a new rubber seal and seems to be trouble-free. Thanks Ray Crowe @ Malloy Mazda for the parts.
