2014-2017 Ford Fiesta, 2018-2019 Focus and Ecosport vehicles equipped with a 1.0L Ecoboost engine may exhibit coolant consumption, white smoke and/or a rough running condition.
Refer to the extended coolant pressure test in the workshop manual section 303-03. If no external coolant loss is confirmed, further investigation of the integrated exhaust manifold (IEM) interface is required. Carefully inspect the manifold port area for cracks and replace if cracks are found.
