thermostat or blown head gasket....
YOU add coolant to the overflow catch tank not directly to the rad,when motor is cold remove catch tank cap,if you can barely touch the fluid with your longest finger then you are ok.do not fill to the top,as is fluid will just overflow on to the ground
On a LX it is located right on the washer fluid tank at the bottom. You will need to pull out the coolant overflow tank. The coolant tank and the washer fluid tank are one unit. it is a piece of cake.
Coolant is old.
Technically, there is no fill cap on the radiator. To add coolant, open the overflow tank. It should be on the Passenger side fender, next to the windshield fluid tank. The coolant tank is pressurized when the engine is hot. Be very careful removing the cap to the coolant overflow if the engine has been running, since the scalding hot coolant can burn you.
thermostat is stuck shut
Sounds like they are for sensor's (fluid level and heat)
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.

in the overflow tank
how do I replace my 2005 fiesta expansion header tank
The overflow tank is either cracked or its overheating and leaking from the cap
Its either in the coolant overflow tank or in the side of the radiator
