Coolant use, white smoke and rough running on the 1.0 EcoBoost: crack in the head next to the integrated manifold

Engine / equipment

1.0 EcoBoost three-cylinder: Fiesta, Focus, EcoSport, B-Max and C-Max

Period mentioned

2014–2019

Symptoms

The coolant level drops with no visible leak, white smoke comes from the exhaust and the engine runs rough (a cylinder misfires).

Possible cause described

Ford technical message SSM 47587 (October 2018) for the 2014–2017 Fiesta, 2015–2018 Focus and 2018–2019 EcoSport with the 1.0 EcoBoost says to run the extended cooling-system pressure test first and, if there is no external loss, inspect the exhaust manifold area integrated in the cylinder head: if there is a crack around the exhaust ports, the parts are replaced.

Check for the garage

Do not keep driving if the coolant keeps dropping: the 1.0 EcoBoost is damaged if it overheats. The garage pressure-tests the cooling system, looks for external leaks and, if there are none, carefully inspects the exhaust manifold area of the head for cracks.
