2012-2017 Ford Focus coolant jar overflow and coolant boiling

[@speedingAtI94]

The legendary Ford quality right there. No wonder police can't catch anybody with their Ford, fix me daily, explorer as their cruiser.

i Also have a Ford Focus 2014 SE,,But if you didn't hear him too Good yes he say (Fan control module),,,Also i didn't change it yet,But when i do i will let you guys know if it works or not,,Because it could be the coolant sensor or water pump,,But worst case scenario a blown head Gasket which is very expensive$$$ ,,,But I rule out Leaks because there's no leaks in my coolant hose or my coolant container or radiator,,,So its best to try the cheapest way first,,which is looking for leaks in the coolant container and in the hose itself,Also Starting with the coolant sensor if the temperature on dash is very high,,,

Hi does the fan run when the fan module is gone

No, the fan stops working, causing the overheat. The cause of it being the fan control module, if the relay checks out OK.

​@@countryroadautopartsusa6466 My fan works but it's still boiling and spilling coolant out of the reservoir...

@@Network126 I suggest you have the fan control module replaced. Yours could be malfunctioning. Works and does not work.
