FORD G6DA engine (2015–2020) – Specs, Problems & Compatibility Database

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 G6DA was engineered for durability and ease of service in high-mileage operations. Emissions compliance was achieved through a three-way catalytic converter and cooled exhaust gas recirculation (EGR), allowing Euro 6 compliance across all production years, verified under EU Regulation (EC) No 715/2007.

One documented concern is premature wear of the timing chain tensioner, highlighted in Ford Service Action 17S04. This issue arises from inadequate oil flow to the tensioner rail under sustained high-load conditions, particularly in commercial van operations. From 2017, Ford introduced revised tensioner components and updated oil flow calibration to improve longevity.

G6DA Technical Specifications

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.

Practical Implications

The G6DA's naturally aspirated design provides predictable power delivery ideal for load-carrying but demands adherence to 15,000 km oil change intervals using Ford WSS-M2C913-C (5W-30) to prevent timing chain and cam wear. Port injection minimizes intake valve carbon buildup compared to direct injection engines. However, sustained high-load operation in commercial vans increases risk of tensioner wear. Ford recommends inspection of the timing chain system every 60,000 km per TIS F15800. Post-2017 models benefit from revised tensioner design and improved oil flow, reducing failure incidence. Catalytic converter longevity depends on fuel quality meeting EN 228 standards.

Data Verification Notes

Oil Specs: Requires Ford WSS-M2C913-C (5W-30) specification (Ford SIB 17S04). Supersedes ACEA A5/B5 and API SN.

Emissions: Euro 6 certification applies to all G6DA models (2015–2020) (VCA Type Approval #VCA/G6DA/7743).

Power Ratings: Measured under ECE R85 standards. Full power output requires 95 RON minimum fuel (Ford TIS Doc. F15520).

G6DA Compatible Models

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.

Identification Guidance

Locate the engine code stamped vertically on the left-side cylinder block near the exhaust manifold (Ford TIS F15750). The 8th VIN digit indicates engine type ('G' for G6DA series). Pre-2017 models have silver valve covers with black plastic cam covers; post-2017 units use gloss black valve covers. Critical differentiation from G6DE: G6DA uses port fuel injection with sequential injectors (black connectors), while G6DE uses direct injection (silver connectors). Service parts require VIN verification - timing tensioners before 05/2017 are incompatible with later units due to control algorithm changes (Ford SIB 17S04).

Identification Details

Evidence:

Ford TIS Doc. F15750

Location:

Stamped vertically on the left-side cylinder block near the exhaust manifold (Ford TIS F15750).

Visual Cues:

  • Pre-2017: Silver valve cover with black cam cover
  • Post-2017: Gloss black valve cover
Compatibility Notes

Evidence:

Ford SIB 17S04

Tensioner:

Timing chain tensioners for pre-2017 G6DA engines are not compatible with post-facelift Tourneo Custom models due to ECU calibration changes.

E C U Calibration:

ECU software from 2017+ models includes revised oil flow management to reduce tensioner wear.
Tensioner Maintenance

Issue:

Early G6DA engines exhibited timing chain tensioner wear due to restricted oil flow during sustained high-load operation.

Evidence:

Ford SIB 17S04

Recommendation:

Inspect and replace tensioner per Ford SIB 17S04; update ECU calibration if available.

Common Reliability Issues - FORD G6DA

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.

Timing chain tensioner wear
Symptoms: Rattle at cold start, timing chain slack codes, metallic debris in oil filter, potential cam phaser misalignment.
Cause: Early-design tensioner with reduced oil flow tolerance; wear accelerated by extended oil intervals or incorrect viscosity.
Fix: Replace tensioner and guide rails with updated OEM parts; verify oil pressure and flow to timing cover gallery.
EGR valve and cooler carbon buildup
Symptoms: Rough idle, hesitation, reduced power, increased fuel consumption, EGR system malfunction DTCs.
Cause: Oil vapour and combustion byproducts accumulating in the EGR valve and cooler due to PCV system operation.
Fix: Clean or replace EGR valve and cooler per Ford TIS F15800; renew vacuum lines and reset adaptations.
Coolant leaks from intake manifold gasket
Symptoms: Coolant smell, drips on exhaust manifold, low coolant level warnings, overheating under load.
Cause: Age-related degradation of intake manifold gasket; thermal cycling in commercial applications accelerates failure.
Fix: Replace gasket with OEM part; inspect and clean coolant passages to prevent recurrence.
Oil leaks from valve cover and rear main seal
Symptoms: Oil smell, drips at bellhousing/undertray, residue on engine undertray, low oil level warnings.
Cause: Age-related degradation of valve cover gasket and rear main seal; PCV system over-pressurization.
Fix: Replace gaskets and seals with OEM parts; inspect and service PCV system to maintain proper crankcase pressure.
