Ford 2.0tdci G6DA / G6DG / UKDA engine

Ford 2.0tdci G6DA / G6DG / UKDA engine is the replacement-engine listing for the Ford model and code shown in its name. G6DA is a 2.0-litre Duratorq TDCi common-rail diesel code used in Ford Focus applications, commonly rated about 100 kW (136 PS). UKDA is another 2.0 TDCi code seen in Ford applications, but the shared capacity does not establish identical turbo, injection, emissions or mounting equipment. The title includes G6DG as well, so verify the exact code on the engine.

Ford 2.0tdci G6DA / G6DG / UKDA engine specifications and identification

• Engine code: G6DA/UKDA
• Displacement class: 2.0td
• Fuel: Diesel
• Induction: Turbocharged
• Listed application: Ford 2.0tdci G6DA / G6DG / UKDA engine

Ford used related engine families across several generations and regional model ranges. Engine code, production date and vehicle identification are more reliable than a general description such as “1.4 Fiesta” or “2.0 TDCi.” Some product titles also group different codes together. Ask the seller to confirm the code stamped on the actual engine and whether it matches the recipient car’s calibration, emissions system and transmission. A shared capacity does not by itself establish that a replacement is a direct fit.

Fitment checks for G6DA/UKDA

Confirm whether the recipient is Focus, Mondeo or another Ford application, and record model generation, VIN, gearbox and emissions package. Compare the complete engine code and donor build details. Inspect the high-pressure pump, injectors, turbo, EGR/DPF equipment, sump and brackets. Ask which ancillaries are included and which are to transfer from the original engine.

Before ordering, compare the old and replacement engines as assemblies. Check sump clearance, mount brackets, gearbox interface, starter position, alternator and air-conditioning brackets, intake and exhaust connections, coolant outlets and sensor plugs. Confirm whether the supplied unit includes its turbocharger or injection equipment, manifolds, fuel rail, injectors, sensors and wiring. If parts need to be transferred, identify them in advance and have the workshop assess their condition. Request written confirmation when the listing includes multiple codes or model families.

Preparing and installing the G6DA/UKDA engine

Before a common-rail diesel replacement, identify the initial failure and inspect fuel quality and contamination, turbo oil feed, intercooler and intake. A damaged injector or turbo can affect components beyond the engine. Replace filters and service items according to the exact vehicle procedure. Following fitment, check rail pressure, boost, injector correction data, oil pressure, coolant temperature and DPF/EGR-related faults with a suitable diagnostic tool.

Use the correct service data for the exact recipient vehicle when selecting oil, coolant, filters and installation procedures. Repair the original fault before startup. Check for leaks around the engine, fuel connections, cooling circuit and lubrication system, then scan the ECU for stored or pending codes. Record any warning lights or abnormal sounds rather than continuing to run the engine. A careful first-start inspection can catch wiring, fuel, boost or cooling problems while they are still straightforward to correct.

Order the correct Ford 2.0tdci G6DA / G6DG / UKDA engine

When enquiring, send the VIN, engine code, model year, gearbox details and a photograph of the original stamping. Ask whether the supplied unit is a complete engine or a long block and confirm the included components. For code discrepancies in the product name, confirm exactly which variant is available before paying or arranging installation. Browse the current engine and gearbox catalogue and compare the replacement with the vehicle specification.

For technical background, consult Ford 2.0 Duratorq TDCi workshop specifications. This information helps explain 136 PS G6DA data and the separate UKDA code family, while final fitment should be established from the stamped engine code and recipient VIN. A correctly identified Ford 2.0tdci G6DA / G6DG / UKDA engine gives the installer a clear basis for matching components and planning commissioning.
