The Ford 4GF is a 1,998 cc, inline — four turbocharged petrol engine introduced in 2018 as part of the EcoBoost family, specifically designed for transverse front — wheel — drive applications. It features direct fuel injection, a single — scroll turbocharger, and dual overhead camshafts (DOHC) with Ti — VCT. In standard tune it produces 147 kW (200 PS), with torque output of 320 Nm, supporting a broad torque curve ideal for everyday driving.
Fitted to models such as the Focus S…
All 4GF engines meet Euro 6d-TEMP standards .
The Ford 4GF is a 1,998 cc inline-four turbocharged petrol engine engineered for compact and mid-size Ford models (2018–2023). It combines direct injection with a single-scroll turbocharger to deliver strong mid-range torque and responsive throttle behavior. Designed to meet Euro 6d-TEMP emissions standards, it balances performance with real-world drivability.

The Ford 4GF was used across Ford's C2/C5 platforms with transverse mounting and front-wheel drive layout. This engine received platform-specific tuning—slightly revised intake manifolds in the Kuga and enhanced NVH damping in the Focus—and from 2020 the updated intake port geometry and ECU calibration in facelifted models created minor service part distinctions. 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 4GF engine is generally reliable when maintained properly, though pre-2020 models are prone to intake carbon buildup. Later units with revised intake ports show improved durability. Regular oil changes with Ford-spec 5W-30 and periodic intake cleaning help ensure longevity beyond 150,000 km.
Key issues include intake valve carbon buildup, turbo actuator sticking, GPF clogging due to short trips, and coolant leaks from the water pump. These are documented in Ford service bulletins and addressed through component updates and maintenance protocols.
The 4GF engine powers the Focus Mk4 (200 PS), Kuga Mk3 (200 PS), and Escape Mk4 (245 PS in North America), all equipped with the 2.0L EcoBoost petrol variant. It replaced earlier 2.0L naturally aspirated units and was succeeded by Gen 3 EcoBoost in performance applications.
Aftermarket ECU tuning is common on the 4GF 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.
In a Focus 2.0T (200 PS), combined consumption is ~7.6 L/100km (~37 mpg UK). Real-world figures vary: urban driving may see 9–10 L/100km, while highway cruising achieves 6.5 L/100km. GPF regeneration cycles temporarily increase fuel use.
Yes. The 4GF is an interference engine. If the timing chain fails or jumps, pistons can contact valves, resulting in catastrophic internal damage. Regular inspection of chain tensioners and guides is essential to prevent failure.
Ford specifies SAE 5W-30 oil meeting WSS-M2C949-A standard. This low-SAPS formulation protects turbo bearings and GPF systems. Change oil every 15,000 km or annually, and use RON 95 unleaded fuel for optimal performance.
