TRY THIS

Hey Guys try this, when your car is cool take off your radiator cap and smack the little float around a few times. Sometimes they get stuck? I wish my problem was that easy but my light is on and I have coolant leaking everywhere.
"craked t-stat housing I think!

Is your intake cracked? If you have an intake with the plastic coolant crossover then you have the same intake that was silent recalled for the '96 and '97s. But the '98s and '99s and even some '00s had the same defective intake. I had to replace my intake with one that has the aluminum crossover.

Mine has a real sticky float.....for some reason i free it up, and its crappy the next time i drive the car.....betcha thats the problem. Open the radiator cap (with the engine COLD of course) and stick your finger in there and work it up and down (kinda like prom night), and that will knock it loose. Good Luck!

Thanks for the suggestions, i will try "fingering" the float and see if that works. I have the intake with the aluminum crossover.

i had this same problem. I think the sensor in our mustangs are really sensitive. I did a search and found some really good stuff.

Speak of the devil... my coolant light came on today... right when I started the car... drove around the block, turned off checked everything... everything is fine, the coolant is a little dirty so I probably will flush it... but the light hasn't come on since...

I will go to autozone and have them pull the codes and see if something else shows up
