The Ford G6DE is a 2,360 cc, inline — five naturally aspirated petrol engine produced between 2004 and 2010. Part of the Ford Duratec family, it was engineered for smoothness and linear power delivery in mid — to — large vehicles. Featuring dual overhead camshafts (DOHC) and 20 — valve configuration, it delivered 127 kW (173 PS) and 223 Nm of torque, utilising variable cam timing (Ti — VCT) to enhance low — end responsiveness and high — RPM efficiency.

The Ford G6DE is a 2,360 cc inline-five petrol engine engineered for mid-size passenger vehicles (2004–2010). It combines Ti-VCT variable cam timing with port fuel injection to deliver smooth throttle response and consistent fuel economy. Designed to meet Euro 4 emissions standards, it balances refinement with long-term serviceability for high-mileage applications.

The Ford G6DE was used across Ford's CD3 platform with transverse mounting and shared architecture with Volvo pre-2010 derivatives. This engine received platform-specific adaptations-shorter intake manifolds in the Mondeo and revised exhaust routing in the S-MAX-and from 2007 received internal timing chain upgrades to address early tensioner wear, creating interchange 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 G6DE is generally reliable when maintained properly, but early models (2004–2006) are prone to timing chain tensioner issues if service intervals are exceeded. Post-2007 revisions significantly improved chain system durability. Using correct 5W-30 specification oil and adhering to 150,000 km or 8-year timing chain replacement greatly enhances longevity. Well-maintained units regularly exceed 200,000 km without major repairs.
Key issues include timing chain tensioner wear (especially pre-2007), throttle body carbon buildup causing rough idle, coolant leaks from the thermostat housing, and ignition coil failures. These are documented in Ford service actions and technical bulletins. Carbon buildup is common in short-trip driving, requiring periodic cleaning.
The G6DE powered several Ford models including the Mondeo Mk3 (2004–2010) and S-MAX (2006–2009). It was also used in pre-2008 Volvo S40/V50 models as the B4204S1. All applications met Euro 4 emissions standards throughout production.
Limited tuning potential exists. ECU remaps typically yield +10–15 kW due to the naturally aspirated design and compression ratio. Intake and exhaust upgrades offer minor gains. However, the engine is not designed for forced induction. Over-aggressive tuning risks cam timing errors and lean conditions, so conservative tuning with supporting modifications is advised.
In a Mondeo 2.3i, combined consumption is approximately 9.2 L/100km (30.7 mpg UK). Highway driving can achieve ~7.5 L/100km (37.7 mpg UK), while city use may exceed 11.0 L/100km (25.7 mpg UK). Real-world economy depends on driving style, but 28–32 mpg (UK) is typical for mixed conditions with a well-maintained engine.
Yes. The G6DE is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in bent valves or damaged pistons. Immediate attention to chain noise or service intervals is essential to prevent catastrophic damage.
Ford specifies WSS-M2C913-C (5W-30) synthetic oil. This formulation ensures proper cam phaser operation and journal lubrication. Change oil every 15,000 km or 12 months, whichever comes first. Using non-approved oils increases the risk of chain wear, particularly in pre-2007 engines.
