ABOUT THE
JAGUAR AJ20 ENGINE
The AJ20 is a 2.0-litre inline-four diesel engine sourced from Ford's Duratorq / Puma family, fitted to the Jaguar X-Type (X400) from 2003 to 2009. It's one of the diesel options in the X-Type range, alongside the later ZSD-420 2.2-litre diesel and the petrol V6 options. The engine is based on Ford's Puma architecture, a widely-used diesel platform that appeared across multiple Ford, Mazda, and PSA vehicles during this period.
JAGUAR AJ20
APPLICATIONS BY MODEL
The AJ20 was fitted exclusively to the X-Type in the UK market, specifically in the 2.0D variant (X400 generation, 2003-2009). It served as the entry-level diesel option in the X-Type range, offering a balance of fuel economy and performance that suited the saloon and estate body styles.
JAGUAR AJ20
ENGINE COMPATIBILITY
The AJ20 is a Ford-sourced engine fitted to the X-Type during its production run. Compatibility comes down to confirming your exact model and year, which we do by registration. Engine ancillaries, mounting, and ECU calibration are specific to the X-Type application.

JAGUAR AJ20 REBUILD VS REPLACEMENT VS USED
Rebuilding Your AJ20 Engine
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Jaguar already has instead - strip it down, pressure-test it, and replace every worn or damaged component with updated OEM parts. You get a near-new engine with a 12-month unlimited-mileage warranty, without the compatibility risk of an unknown used unit. This is the option most AJ20 owners choose, and it's the one we'd recommend for most situations.
- Strip down & inspect
- Pressure-test
- Replace worn components
- 12-month unlimited-mileage warranty
Replacement AJ20 Engines
If your existing engine is beyond economical repair, we also offer full engine replacement and fitting - sourced and fitted by our team, with the same 12-month unlimited-mileage warranty.
- Supplied & fitted by our team
- OEM quality
- 12-month unlimited-mileage warranty
Used AJ20 Engines
In some cases, a matched low-mileage used engine is the right call - particularly if you need your car back on the road quickly and your existing engine's damage is extensive. We can source and fit these too, though most owners who ask about used engines end up choosing a rebuild once they understand the compatibility risk a used unit carries. Enter your reg below and we'll talk you through both options honestly.
- Low-mileage units
- Quick turnaround
- Condition risk - we advise honestly

Reconditioned, Refurbished or Remanufactured?
JAGUAR AJ20 RECONDITIONED ENGINES
"Reconditioned" is the term many owners search for when they mean the same thing as a rebuild - a full strip-down, inspection, and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.
→ Our rebuild service is exactly that.
JAGUAR AJ20 REFURBISHED ENGINES
"Refurbished" often describes the same process from a different angle - restoring your existing engine to full working condition rather than replacing it outright. Our rebuild covers this.
→ Our rebuild service covers this.
JAGUAR AJ20 REMANUFACTURED ENGINES
Some owners specifically search for a "remanufactured" engine, expecting a unit rebuilt to original specification with updated components. That's consistent with what our rebuild service delivers.
