You need to replace the coolant temp sensor it's the bottom sensor.Make sure you get a brass tipped one the plastic tipped one's crack.Make sure the engine is cold when you change it you will loose coolant.Also inspect the connector going to it if it's corroded then you will have to replace the connector too.
