The Ford F39A is a 1,596 cc, inline — four naturally aspirated petrol engine produced between 2011 and 2018. It forms part of the Ford Sigma engine family, featuring double overhead camshafts (DOHC) and variable cam timing (Ti — VCT). Delivering 85 kW (115 PS) and 155 Nm of torque, it was engineered for compact vehicle applications with an emphasis on fuel efficiency and low maintenance.
Fitted to models such as the Ford Focus Mk3, C — Max, and EcoSport, the F39A was designed for…
Production years 2011–2018 meet Euro 5 standards .
The Ford F39A is a 1,596 cc inline-four petrol engine engineered for compact and subcompact models (2011-2018). It combines Ti-VCT (Twin Independent Variable Cam Timing) with sequential multi-point fuel injection to deliver responsive low-RPM performance. Designed to meet Euro 5 emissions standards, it balances everyday drivability with fuel economy and low CO₂ output.

The Ford F39A was used across Ford's C1 platform with transverse mounting. This engine received platform-specific adaptations-shorter accessory drives in the EcoSport and revised intake manifolds in the Focus-and from 2015 the facelifted Focus Mk3.5 adopted minor ECU recalibrations, creating software compatibility limits. 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 F39A is generally reliable when maintained properly, but pre-2015 models are prone to timing chain tensioner wear. Later revisions (post-2015) improved durability with updated components. Regular oil changes using Ford WSS-M2C946-B (5W-30) and inspection of the tensioner per SIB 14S04 significantly enhance longevity.
The most documented issues are timing chain tensioner wear (causing rattle), intake carbon buildup affecting idle quality, catalytic converter failure due to oil contamination, and valve cover oil leaks. These are confirmed in Ford service bulletins and field reports.
The F39A was used in the Ford Focus Mk3 (2011–2018), C-Max (2011–2018), and EcoSport (2013–2018), all designated as 1.6L Ti-VCT petrol variants. It was not used outside the Ford lineup or in other brands.
Limited tuning potential exists. ECU remaps can yield +10-15 kW by advancing timing and optimizing fuelling, but gains are modest due to natural aspiration. Supporting mods like intake and exhaust upgrades offer minimal returns. Over-advancing timing risks knock, so conservative tuning is advised.
In a Focus 1.6 Ti-VCT, combined consumption is ~6.8 L/100km (41.5 mpg UK). City driving may see 8.0 L/100km (35 mpg), while highway runs can achieve 5.8 L/100km (48 mpg). Real-world figures depend on driving style, but 38-44 mpg (UK) is typical for mixed use.
Yes. The F39A is an interference engine. If the timing chain fails or jumps, pistons can strike open valves, resulting in bent valves or piston damage. Immediate attention to chain rattle is essential to avoid costly repairs.
Ford specifies 5W-30 synthetic oil meeting WSS-M2C946-B standard. Change intervals should not exceed 15,000 km or one year. Using correct oil ensures proper tensioner function and minimizes wear on the timing chain and VCT system.
