Parts for your 2010 Ford Fiesta-Head gasket

2010 Ford Fiesta head gasket: what it does, why it matters, and when to replace it

Technical sources confirm the 2010 Ford Fiesta is fitted with a head gasket. The Ford Workshop Manual for WS/WT Fiesta, Ford service information (ETIS/GSI), and OEM parts catalogues all list a cylinder head gasket and replacement torque-to-yield head bolts for the common 2010 Fiesta engines (Duratec 1.25/1.4/1.6 petrol and Duratorq 1.6 TDCi). Industry repair databases and manuals (e.g., Haynes and Autodata) also specify tightening sequences and angles for the cylinder head on these motors, which only applies when a head gasket is present.

On the 2010 Fiesta, the head gasket is a multi-layer steel seal clamped between the engine block and the cylinder head. Its job is twofold: keep combustion pressure in the cylinders and keep oil and coolant in their own passages, without mixing. When it’s healthy, the engine runs sweet as — good compression, stable temps, clean oil, and no bubbles in the coolant. If it fails, performance drops, overheating risks go up, and repairs get more involved.

A head gasket isn’t a routine service item
