The Ford F41A is a 1,596 cc, inline — four petrol engine produced between 2002 and 2008. It formed part of the Ford Duratec HE engine family, designed for compact and mid — size applications. Featuring double overhead camshafts (DOHC), 16 — valve configuration, and sequential multi — point fuel injection, it delivered 85 kW (115 PS) with 155 Nm of torque, providing balanced performance and fuel efficiency.
Fitted to models such as the Ford Focus Mk2, C — Max, and Mondeo Mk3, the…
Production years 2002–2004 meet Euro 3 standards; 2005–2008 models may have Euro 4 compliance depending on market .
The Ford F41A is a 1,596 cc inline-four petrol engine engineered for compact and family vehicles (2002–2008). It combines DOHC 16-valve architecture with sequential multi-point fuel injection to deliver responsive mid-range performance. Designed to meet Euro 3 (and market-specific Euro 4) standards, it balances drivability with emissions efficiency.

The Ford F41A was used across Ford's C1/CD3 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Focus and revised exhaust routing in the Mondeo-and from 2005 the facelifted Focus Mk2 and C-Max adopted updated engine management software, creating minor calibration differences. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F41A offers solid performance and fuel efficiency, but early models (2002-2004) had reliability concerns, particularly camshaft wear. Later revisions (post-2005) improved oil flow and durability, so well-maintained examples can exceed 200,000 km. Regular servicing and using correct oil (5W-30 Ford WSS-M2C913-A) significantly enhance longevity.
The most frequent issues include camshaft wear (especially in pre-2005 engines), intake carbon buildup, lambda sensor failure, and coolant leaks from the thermostat housing. These are documented in Ford service bulletins and field reports, with camshaft issues being the most critical if neglected.
The F41A was used in several Ford models including the Focus Mk2 (2004–2008), C-Max (2003–2007), and Mondeo Mk3 (2002–2007). It was typically offered as the 1.6i or 1.6 Zetec variant, primarily in European markets with Euro 3 or Euro 4 compliance depending on model year.
Aftermarket ECU tuning is common on the F41A platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Good for a naturally aspirated petrol engine. In a Focus 1.6i (2005), typical consumption is ~8.5 L/100km (city) and ~5.8 L/100km (highway), or about 40 mpg UK combined. Real-world figures vary, but expect 35-45 mpg (UK) on mixed driving for a well-maintained F41A.
Yes. The F41A is an interference engine. If the timing chain fails or jumps, pistons can collide with open valves, causing severe internal damage. Chain maintenance is crucial—any abnormal noise should prompt immediate inspection.
Ford specifies a 5W-30 synthetic oil meeting WSS-M2C913-A spec. Use of correct oil ensures proper camshaft lubrication and reduces wear. Change intervals should not exceed 15,000 km or one year, whichever comes first, to maintain engine health.
