coolant light

my sensor light came on (red box with red arrow pointing down)........... so i flushed the coolant till all that was seen was clear water then using coolant flush it was soapy looking so i ran that till all was clear,,,,,then drained radiator,,and added coolant,,,the light remains on? and coolant level is right,car runs fine,,
how do i turn off sensor light,,?
any idea's?
2000 intrigue,,,,,,,1.5 engine, auto,,116,ooo miles,no manual came with car,seems to be way of these cars and i went to napa,advanced auto ,pep boys and others,,and they don't carry it,,and don't even show it in there books to order..no chilton or haynes has 2000 intrigue..

thanks

the coolent light sensor is like a float if it does not turn off with a full system then the level switch is defective and must be replaced.

thank you,,,,,

How much does one of those sensors cost. i have found very little info on the problem.

and i have the 3.8 i havent tried doing the reset like you would do with the change oil soon light.

Try gmpartsdirect.com. I replaced one in my old '98 a couple of years ago and I believe I paid $60 for that thing - from a dealer. It seemed to work for a while but now it is back to its old tricks. What can I say? GM!!
