Side-by-side reliability comparison
Specifications
Character
EcoBoost 1.6
"Ford's first four-cylinder EcoBoost (2010-2017): 1.6 litres, direct injection, turbo, timing belt. Fitted to the Focus III, C-Max II, Kuga II, Fiesta ST and ST200, Mondeo, S-Max, Galaxy, Transit Connect and, as the B4164T, to Volvo T3/T4 models. Strong and lively, but very sensitive to coolant loss: with too little coolant the cylinder head can overheat and crack, leak oil under pressure and, in rare cases, start an engine-bay fire. Ford recalled engines built 2010-2014 worldwide (845 cars in Greece) to fit a coolant level sensor. Check the recall was done, watch the coolant level and change the timing belt on time."
1.8 TDDi / DI (Endura-DI)
"Pre-common-rail Ford 1.8 diesel (Focus Mk1 TDDi 75/90 hp, Fiesta Mk4 1.8 DI). Direct injection with an electronically controlled rotary pump. Owners rate it far better than the later 1.8 TDCi; the injection pump and its control unit are the one known weak point, typically after 120,000 km."
