Jaguar XJ6ENGINE OPTIONS
Every XJ6 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XJ6 ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XJ6 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 XJ6 owners choose, and it’s the one we’d recommend for most situations.
From £3,200RECONDITIONED XJ6 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.
Learn moreREFURBISHED XJ6 ENGINES
Similarly, "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.
Learn moreREMANUFACTURED XJ6 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 on the AJ16.
Learn moreREPLACEMENT XJ6 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 warranty.
Learn moreUSED XJ6 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.

We supply low-mileage, VIN-matched used units too, and offer full replacement and fitting. However, most XJ6 owners choose a rebuild once they realise it removes compatibility risk and works out more cost-effective over the life of the car.

ABOUT THE Jaguar XJ6 ENGINE
The XJ6 was a core part of the Jaguar XJ range from 1994 to 2003, spanning the X300 and X308 generations. Across both, it used the AJ16 - a 3.2- to 4.0-litre inline-6 petrol engine. This was Jaguar’s final straight-six before the switch to V8s, and it remains a respected unit for its smoothness and character. The XJ6 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

Jaguar XJ6 ENGINE COMPATIBILITY
Because the XJ6 uses the same AJ16 engine family across both generations, compatibility is straightforward once we confirm the exact variant and year. However, there were running changes during production, so we always verify your specific engine by registration or VIN before quoting or sourcing any parts. This ensures we fit the correct timing components, gaskets and ancillaries for your exact build.
