Early Ford Fiesta 1.0 EcoBoost engines (pre-2019, e.g., M1JC, SFJA) use a "wet" timing belt that runs in engine oil and is prone to degradation. Later models (2019 onwards, e.g., M1DA) transitioned to an improved belt design and eventually a timing chain in mild-hybrid variants, which is far more robust.

• Pre-2019 wet belt engines require strict oil change intervals and belt replacement every 10 years/150,000 miles.
• Post-2019 chain-driven variants eliminate the wet belt degradation risk entirely.

A standard Ford Fiesta 1.0 EcoBoost engine swap typically takes 1 to 2 days of labour once the replacement unit has arrived.

• Sourcing and delivering the engine usually takes 2-4 working days.
• Total turnaround from quote to completion is generally 5-7 working days.
