Ford 2.0tdci G6DA / G6DG / UKDA engine
R19,500.00
The Ford 2.0 TDCi G6DA, G6DG, and UKDA are highly similar 2.0-litre turbocharged diesel engines from the Duratorq family (specifically the PSA-Ford DW10 development). These 16-valve, four-cylinder units are commonly found in the Ford Kuga Mk1 and Ford Focus Mk2.
Technical Overview
These engine codes are often interchangeable in many applications, though they were phased in to meet evolving emissions standards.
| Feature | G6DA / G6DG | UKDA |
|---|---|---|
| Displacement | 1,997 cc | 1,997 cc |
| Power Output | 100 kW (136 PS) | 100 kW (136 PS) |
| Max Torque | 320 Nm (up to 340 Nm with overboost) | 320 Nm |
| Emissions Standard | Euro 4 | Euro 5 |
| Compression Ratio | 18:1 | 16:1 (typical for Euro 5) |
| Fuel System | Siemens/Continental Common Rail | Delphi Common Rail |
Key Differences & Applications
- G6DA / G6DG (Euro 4): Primarily used in the Ford Focus Mk2, C-MAX, and early Kuga Mk1 (2008–2010).
- UKDA (Euro 5): Introduced later (roughly 2010 onwards) for the Ford Kuga Mk1 to meet stricter emissions, often featuring a different Diesel Particulate Filter (DPF) setup and Delphi fuel injection components.
Common Maintenance & Issues
- Timing System: Driven by a timing belt. While Ford suggests long intervals, mechanics generally recommend replacement every 10 years or 150,000 km to prevent engine failure.
- Oil Specifications: Requires 5W-30 oil (meeting Ford WSS-M2C913-B/C/D) with a capacity of approximately 5.5L to 6.1L depending on the specific model and filter.
- Vulnerabilities:
- EGR Valve: Prone to carbon buildup, causing rough idling or limp mode.
- Turbo Solenoids: The turbo boost control solenoid can fail, leading to sudden loss of power.
- Dual Mass Flywheel (DMF): Rattling or vibration during clutch engagement often indicates a worn DMF.
