SSM 472652018-05-21. Service bulletin. ENGINE AND ENGINE COOLING. Some Ford and Lincoln vehicles equipped with a 2.7L or 3.0L EcoBoost engines may exhibit an oil leak from the engine oil pan RTV seal. Replace the oil pan by performing the published Workshop Manual (WSM) service procedures. After removing the oil pan, it is suggested to allow the crankcase to drain overnight to minimize the chance of residual oil contaminating the crankcase sealing rail. Remove all traces of old RTV, clean the engine sealing surface with only Motorcraftù Metal Brake Parts Cleaner then wipe with Motorcraftù Metal Surface Prep Wipes, and allow to air dry as directed in WSM, Section 303-00, RTV Sealing Surface Cleaning and Preparation. If possible, after the new oil pan is installed, allow the new RTV sealant to cure for 4 hours before refilling the engine with oil. Ford is investigating this concern. Monitor OASIS for future updates.
SSM 472042018-05-21. Service bulletin. ENGINE AND ENGINE COOLING. Some 2015-2018 Fusion/MKZ/MKC/Escape/Edge vehicles equipped with a 2.0L EcoBoost engine may exhibit a runs rough condition with DTCs P0300, P0301, P0302, P0303, P0304 and/or P0316. This may be due to coolant intrusion due to corrosion on the engine block. To diagnose this concern, with the engine at normal operating temperature, pressurize the cooling system to 138 kPa (20 psi) and hold for 5 hours. If the coolant pressure drops 27.57 kPa (4psi), remove the spark plugs and inspect for coolant in the cylinders. If coolant is found in any of the cylinders, replace the engine long block assembly. Follow normal prior approval process for your Dealership. However, follow the diagnostic repair procedure in this article to determine correct repair. For claiming, use causal part 6006 and applicable labor operations in Section 6 of the SLTS Manual.
