Flashing coolant light

[frd906]

Hey guys, 99 Series 1 Au Forte

I noticed yesterday before i drove off that my low engine coolant light came on and started flashing at me, i checked the coolant level and it was all perfectly normal, the car dosent over heat or anything like that, its not leaking and its fine,

I turned the car off then back on and it dissapeard all together never came back on all day,

Then it did it the same thing today,

Im stumped, Im going to change the coolant tommoro and give the car a flush,
