Coolant Warning Light Stays On

[Robe]

Despite the radiator coolant being at the right level the coolant warning light is staying lit up for around five minutes in the morning.

Advise me please, AU gurus.

Thanks

might need a new sensior.
the company run about (el futura) has the same thing but it wont turn off at all even after we put 2 new ones in, only time it will turn off is if you make a sharp turn left then right, but will come straight back on as soon as you stop(yes it has coolant in it).

replace the sensor. i found that the sensor used in my EA was the same as my dads AU fairmont. my EA has only done 157,000 and the float became water logged, so therefor didnt float to well!
