When I start up my 2005 STS V8 it says check coolant on the dash but when I checked the coolant it is fine.

Yes, this sensor is VERY sensitive,It may just need 8 to 16 Oz. more.
the level in the overflow tank should be at Half Full.
I had to add a little, DO NOT OVERFILL !
Add 8 oz, and see if that takes care of the Indication.
Add more only if needed , to clear the Indication.

Watch for the smell of coolant after a long drive. My car needed a water pump at about 60,000 (CPO warranty repair).

The drips came from the firewall area.
