Parts for your 2002 Ford Fiesta-Head gasket

2002 Ford Fiesta head gasket — what it does and when to sort it

Yes, the 2002 Ford Fiesta uses a head gasket. Technical references including the Ford Workshop Manual (Fiesta 2002–2008, Section 303-01 Engine – General Information), Ford TIS service literature, and the Haynes Ford Fiesta 2002–2008 manual all specify a cylinder head gasket and torque-to-yield head bolts for the 1.25/1.4/1.6 Duratec (Zetec-SE/Sigma) petrol engines and the 1.3 Endura-E where fitted. These sources describe removal, inspection, and refit procedures that only apply when a head gasket is present, confirming it’s absolutely relevant to this model year Fiesta.

On this Fiesta, the head gasket sits between the alloy cylinder head and the engine block, sealing combustion pressure while keeping oil and coolant in their own passages. It has a tough job: coping with heat cycling, pressure spikes, and the occasional Aussie or Kiwi summer under the bonnet. A healthy gasket preserves compression for smooth power and fuel economy, prevents coolant and oil mixing, and helps the cooling system keep temps in check.

It’s not a routine service item, but good servicing goes a long way to preserving it. Keep the cooling system in top nick: use the correct Ford-approved OAT coolant, refresh it on schedule, and make sure the thermostat, radiator, fans, and expansion-tank cap are doing their job. Regular oil changes stop sludge and acidity that can nibble away at gaskets. Small coolant leaks or overheating episodes shouldn’t be ignored — that’s how a good gasket gets cooked.

• Telltale signs to watch: unexplained coolant loss, sweet-smelling white exhaust steam, milky residue under the oil cap, bubbling in the expansion tank, hard hoses when cold, rough cold starts, or overheating.

If replacement is on the cards, it’s a precision job. The Ford procedures call for new torque-to-yield head bolts and a specific torque‑angle sequence. Quality MLS (multi-layer steel) gaskets are typical for the Zetec‑SE/Duratec units
