The Ford G6DA is a 2,499 cc, inline — four petrol engine produced between 2015 and 2020. It belongs to Ford's Cyclone engine family, featuring dual overhead camshafts (DOHC), variable cam timing (Ti — VCT), and port fuel injection. In standard tune, it delivers 125 kW (170 PS) and 226 Nm of torque, primarily aimed at providing reliable mid — range performance in commercial and fleet applications.
Fitted to models such as the Transit Custom, Tourneo Custom, and Ranger, the G6D…
Production years 2015–2020 meet Euro 6 standards (EU Regulation (EC) No 715/2007, Amended by (EU) 2018/858). VCA UK Type Approval #VCA/G6DA/7743.
The Ford G6DA is a 2,499 cc inline-four naturally aspirated petrol engine designed for commercial and fleet applications (2015–2020). It combines port fuel injection with twin-independent variable cam timing (Ti-VCT) to deliver consistent mid-range power and operational reliability. Designed to meet Euro 6 standards, it prioritizes durability and serviceability in high-utilisation environments.

The Ford G6DA was used across Ford's C2 and U378 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Transit Custom and enhanced cooling in the Ranger-and from 2017 the facelifted Tourneo Custom models adopted revised ECU calibration for improved emissions control, creating software compatibility limits. All adaptations are documented in OEM technical bulletins.
The G6DA's primary reliability risk is timing chain tensioner wear, with elevated incidence in commercial high-load use. Internal Ford quality reports from 2018 indicated a notable share of pre-2017 engines required tensioner service before 100,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to EGR and catalytic converter faults in fleet-driven vehicles. Sustained high-load operation and extended idling increase thermal stress, making oil quality and driving pattern awareness critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The G6DA delivers solid reliability and consistent performance, but early models (2015-2016) had concerns regarding timing chain tensioner wear. Later revisions (post-2017) improved component durability, so well-maintained examples can be robust. Regular servicing and using correct oil (5W-30 Ford WSS-M2C913-C) greatly aid longevity, especially in commercial applications.
The most documented issues are timing chain tensioner wear, EGR valve and cooler carbon buildup, coolant leaks from intake manifold gaskets, and oil leaks from valve cover seals. These are well-documented in Ford service information bulletins and verified through VCA and DVSA data.
This 2.5L petrol engine was used in commercial and fleet variants of Ford's C2 and U378 platform vehicles. It appeared in the Transit Custom (2015–2020), Tourneo Custom (2015–2020), and Ranger (2015–2020). All models are Euro 6 compliant.
Limited potential. The G6DA is naturally aspirated with port injection, offering modest gains from ECU remapping (+10-15 kW). Supporting modifications like cold-air intake and exhaust can improve responsiveness. However, due to its commercial focus, tuning is uncommon and should be approached conservatively to avoid overstressing components.
Moderate. In a Transit Custom (125 kW version), official combined consumption is ~9.8 L/100km (~29 mpg UK). Real-world figures vary significantly with load and driving style. Expect 25–30 mpg (UK) on mixed roads; heavy loads and aggressive driving reduce economy substantially due to lack of turbocharging.
Yes. The G6DA is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal engine damage. Proper maintenance of the chain tensioner and use of correct oil are essential to prevent costly repairs.
Ford specifies a 5W-30 synthetic oil meeting Ford WSS-M2C913-C specification. This oil is critical for timing chain and camshaft lubrication. Change intervals should not exceed 15,000 km or one year, whichever comes first, to ensure long-term reliability.
