Low Coolant Light....
 

My low coolant light comes on and stays on. I have plenty of coolant and have replaced one of the temp sensors. It is the sensor that is near the alternater. It seems that the low coolant light comes on after the car has been on for awhile, or I'm assuming when it hits a certain temp. My temp gauge reads normal, no overheating problems. Is their any other sensors that might be throwing that light, or is there anything else that I can check? There's no performance problems that I can tell, it's just annoying having that light on. Any info is much appreciated. :confused: :confused: :confused:

Probaly a bad sensor.

Not that it is related, but mine comes on whenever I wash the engine bay.

Do you know what other sensors are involved in the whole "coolant temp check"? Like I said previously, I replaced the one sensor that is near the alternator and reset the computer and it still shows the LC Light.

No. Sorry.

It's cool, thanks for the feedback.

The sensor on the passenger side is for the guage,the one on the drivers side is for the computer.Both of these sensors are mounted to the crossover behind the alt.

I'll check it out, thanks.

Side note - Do you have pics of your Sportster?

And pic of the Flathead?

Well, its prolly just the little sensor in the overflow tank sticking. Mine does it when I make a sharp turn, but goes away after a while.
