EcoBoost 1.6
Ford · 1.6 EcoBoost / SCTi / GTDi Turbo I4 (also Volvo B4164T)
2010–2017
"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."

Known Issues 3
Cylinder head overheats and cracks (oil leak, fire risk; recall)
▸Engine overheat warning, coolant level repeatedly low, visible coolant leak, oil leak or burning smell from the engine bay, smoke
If the engine is started cold and driven with coolant well below the minimum mark, the cylinder head heats up quickly, can overheat locally and crack; the crack leaks oil under pressure and oil on hot parts near the turbo can start a fire. Ford knew of 26 underhood fires with a cracked head in North America by March 2017. Recalls: US 12V-551 and 13V-583 (2013 Escape and Fusion: software, shielding and cooling changes), US 17V-209 (208,584 cars built before 14 February 2014: coolant level sensor), and in Europe Fiesta ST, Focus, C-Max, Kuga and Transit Connect built 2010-2014 (plus Mondeo, S-Max and Galaxy in France) get a coolant level sensor with warning and power reduction. Volvo recalled 2013-2015 S60, V60 and V40 1.6 for a cooling modification. The sensor warns the driver; it does not change the head. An engine database puts the repair at EUR 1,000-3,000.
Ford recalled 845 cars in Greece (February 2018). Ask an authorised Ford dealer whether the coolant level sensor recall was done, and check the coolant level often in the Greek summer.
Coolant leaks and coolant loss (cup plug, coolant pump, warm-up)
▸Coolant level falling, coolant smell or drips, low-coolant or overheat warning
Coolant loss is what starts the cylinder head failure. Recalls covered coolant system leaks on 2013 Escape and Fusion 1.6 (US 12V-551, software overheat strategy), a cylinder head cup (freeze) plug that can come out and drain the coolant (US 12V-431, 2013 Escape), and a small coolant leak during warm-up on 2013-2015 Volvo S60, V60 and V40 1.6 (engine modified to cool better while warming up). An engine database also reports a recall for the electromagnetic clutch of the coolant pump. No source gives a repair price.
Top up only with the specified coolant and find the cause of any loss before driving on; heat makes a small leak worse. No Greek-specific data found.
Direct-injection injectors clog
▸Rough idle, misfires, hesitation, higher fuel use
The direct injectors can clog quickly with poor-quality fuel (engine database), and a German used-car guide warns that the EcoBoost direct-injection petrol engines in the Kuga can suffer coked injectors; fuel additives help the injectors but do not clean the intake valves. No source gives a repair price.
Use good-quality fuel from busy stations. No Greek-specific data found.
