Coolant Light

Hey guys new here. I've beenr reading the forums for a while now but just decided to join to get feedback from other mustang owners. I have a 2000 GT Convertible (AOD) with a few mods here and there. I only have 37k miles on my car but for the past few months my coolant light indicator has constantly been on in my gauge cluster. I know this topic has probably been covered somewhere but I couldn't find an answer when I searched. My coolant level is normal, anyone know what the problem is? I heard this happens to a lot of mustangs. Do I need to replace a sensor or wash something off? Any help would be appreciated. Thanks.

Try and slide the coolant hose from the anti-freeze container on tighter with a clamp or something. If that doesn't work try and replace the sensor.

This could be from alot of things... Even though your coolent is full you might have a air bubble in the system.. This bubble could be sitting around the sensor and giving false readings.. to correct this take off your coolant pressure cap and let the car idle for about 20 minutes, watch to see if there any air bubbles... If that doesnt work find your coolant temp sensor and check the wire connection.. make sure it is secure and there is no build up on it... If that is good i would think that there could be a problem with the sensor itself.. i would replace that next and get the codes cleared.. You can do this by unhooking for batt for i think its 20min and recconect. All this is assuming that you are not overheating....Give that a try and post back.

Work Hard....Play Harder.

after a lot of tinkering around, nothing worked, so I just ended up replacing the coolant sensor. Unfortunately, at least for 2000 GTs, the sensor comes with a new tank which cost about $97 plus new coolant. But I guess it was worth it cuz now the light is finally off!

NOrmally if it comes on its because of the sensor. It get "sludged" up if you will. I dont know why these motors leave that kinda residue but they do. You could have just removed the tank and cleaned it out with water. The sensor gets stuck and the light stays on. Coolant services at 30k or 3 yrs will help take care of this residue.

I had cleaned it out and had the whole coolant system flushed late last year. I figured it might go away after that but it didn't. So ultimately, it was a bad sensor.
