Ford Fusion and Escape May Exhibit Coolant Loss
Some 2014-2019 Ford Fusions and 2017-2019 Escapes equipped with a 1.5L Ecoboost engine may exhibit coolant consumption and a white smoke concern.
Follow the cooling system pressure test procedure in the workshop manual, section 303-03. Pressurize the cooling system to 20 psi and hold for five hours.
If cooling system pressure drops 4 psi after five hours and internal engine coolant loss is confirmed, further investigation of the engine block surface to head gasket interface is required. Carefully inspect engine block cylinders and cylinder bore bridges for erosion, pitting and flatness.
Note: Ford has found that all returned cylinder heads pass inspection and may have been reused.
