The Ford F9DB is a 2,495 cc, V6 naturally aspirated petrol engine produced between 2014 and 2020. It was engineered as a durable, smooth powerplant for Ford’s larger vehicles, featuring twin independent variable cam timing (Ti — VCT), sequential multi — port fuel injection, and an aluminium block and head. In standard tune it delivered 147 kW (200 PS) and 255 Nm of torque, offering balanced performance for towing and highway cruising.
Fitted primarily to the Ford Transit Cu…
Production years 2014–2016 meet Euro 5 standards; 2017–2020 models may have Euro 6 compliance depending on market .
The Ford F9DB is a 2,495 cc V6 petrol engine engineered for light commercial vehicles (2014–2020). It combines Ti-VCT with sequential multi-port injection to deliver smooth mid-range power and predictable throttle response. Designed to meet Euro 5 (and select Euro 6) standards, it balances operational reliability with emissions control.

The Ford F9DB was used across Ford's Transit Custom and Transit platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-integrated mounting points for van body variants and revised cooling for high ambient operation-and from 2017 the facelifted Transit Custom (Gen 2) adopted updated ECU calibrations and CCV routing, 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 F9DB is a robust engine when maintained properly. Pre-2017 models are prone to intake carbon buildup if used in stop-start delivery roles. Later revisions improved CCV routing, reducing deposits. Regular oil changes with correct specification (5W-30 WSS-M2C946-A) and periodic intake cleaning greatly enhance longevity. With proper care, 200,000+ km is achievable.
The main issues are intake manifold carbon buildup (especially pre-2017), coolant leaks from thermostat housing, and ignition coil failures. Less commonly, timing chain tensioners may wear with poor maintenance. These are documented in Ford service bulletins like SIB 17B06, which addresses intake system revisions.
The F9DB was used exclusively in Ford's commercial vans: the Transit Custom (2014–2020) and Transit (2014–2019). It was offered as the 2.5 Duratec 200 PS variant. It was not used in passenger cars or SUVs, nor licensed to other manufacturers.
Limited tuning potential exists. ECU remaps can yield modest gains (~10-15 kW) by optimizing fuel and ignition curves, but the naturally aspirated design limits output. No major aftermarket forced induction kits are available. Most owners prioritise reliability over performance, keeping modifications minimal.
In a Transit Custom, combined consumption is approximately 10.5–12.0 L/100km (22–27 mpg UK), depending on load and driving style. Highway driving can achieve ~9.0 L/100km (31 mpg UK), while urban cycles may exceed 13.0 L/100km (22 mpg UK). Real-world economy is highly dependent on vehicle weight and driving conditions.
Yes. The F9DB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact is likely, resulting in severe internal damage. Maintaining proper oil levels and following service intervals is critical to prevent tensioner-related chain issues.
Ford specifies WSS-M2C946-A (5W-30) synthetic oil. This formulation ensures proper hydraulic lifter operation and protects the timing chain system. Change oil every 15,000 km or annually, whichever comes first, to maintain engine health and prevent sludge or wear.
