You may have low coolant in the radiator and it is causing the sensor to flash as the coolant raises and lowers. Check the coolant level in the radiator (not the fill bottle)
You may have air in the radiator and the air pocket may be causing the light to flash. You would need to bleed the air out.
You may have a bad sensor and needs to be replaced. It is located on the passenger side of the radiator below the fill neck (and has a wire going to it)

Why does 2000 Chevy Venture check coolant level message flash when level is OK?
If you are checking the coolant level at the overflow bottle, it may look normal (between the low & high marks). But the coolant level sensor is mounted on the passenger side of the radiator, down several inches from the top. In other words, you need to check the coolant level AT the radiator cap, but only when the engine is COLD. If it is OK at that point and the overflow bottle, then the coolant level sensor most likely needs to be replaced.
