Jaguar X-Type 2.5 V6 Oil Leaks & Coolant System Wear (AJ25 I6)

The AJ25 is a sophisticated 3.0-litre inline-six with an integrated starter-generator and electric auxiliary compressor — a more modern and efficient design than the older AJ25 V6. We replace timing chains, bearings, water pump and gaskets as standard on every AJ25 rebuild.

Because the X-Type 2.5 V6 uses a completely different engine family from the V8 M178 fitted to the X-Type 63 and GT 63 S, parts and rebuild specifications don't cross over between them.

Source: Established AJ25 specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.

Jaguar X-Type 2.5 V6ENGINE OPTIONS

Every X-Type 2.5 V6 is different. That's why we offer the right solution for your engine, your car and your budget.

01MOST POPULAR

REBUILDING YOUR X-TYPE 2.5 V6 ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your X-Type already has instead — strip it down, pressure-test it, and replace every worn or damaged component (ignition coils and valve cover gaskets, along with timing chain components and bearings) 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 X-Type owners choose, and it's the one we'd recommend for most situations.

02

RECONDITIONED X-TYPE 2.5 V6 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.

03

REFURBISHED X-TYPE 2.5 V6 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.

04

REMANUFACTURED X-TYPE 2.5 V6 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 AJ25.

05

REPLACEMENT X-TYPE 2.5 V6 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.

06

USED X-TYPE 2.5 V6 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.

NOT SURE WHICH OPTION IS RIGHT FOR YOU?

Enter your registration below and we'll confirm your AJ25 and talk you through the best solution for your X-Type 2.5 V6, honestly.

ABOUT THE Jaguar X-Type 2.5 V6 ENGINE

Jaguar AMG GT 53 engine and sedan

The X-Type 2.5 V6 uses the AJ25 — a 2.5-litre V6 petrol engine derived from the Ford Duratec family, fitted throughout the X400 generation's production from 2001 to 2009. The V6 engines in the X-Type all share the same fundamental architecture, with the key difference being capacity: 2.0, 2.5, and 3.0-litre variants (AJ20, AJ25, AJ30 respectively). The 2.5 V6 sits in the middle of the petrol range, offering a balance of performance and refinement that made it a popular choice for UK buyers. The X-Type is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

We continue to rebuild and replace AJ25 engines for every X-Type 2.5 V6 on the road.

Jaguar X-Type 2.5 V6 ENGINE CODES

A 2.5-litre V6 petrol engine fitted to the X-Type from 2001 to 2009 (X400). Known for coil-on-plug ignition coil degradation, often accelerated by oil contamination from leaking valve cover gaskets — see the callout above. We replace ignition coils and valve cover gaskets as standard on every AJ25 rebuild, along with timing chain components and bearings where worn. Check Your AJ25 X-Type 2.5 V6 → [link to quote form]

Jaguar X-Type 2.5 V6 ENGINE COMPATIBILITY

Jaguar touring in workshop

Because the X-Type's V6 engines (AJ20, AJ25, AJ30) share the same Duratec-derived architecture but differ in capacity, confirming your exact engine code matters for correct component sourcing — particularly for parts like ignition coils, valve cover gaskets, and timing chain components. Before we quote or supply anything, we confirm:

Your exact engine code (AJ25) via registration or VIN

Your generation (X400)

Drivetrain and ancillary specification

Any electronics or ECU considerations specific to your exact build

This is why we always start with your registration rather than a generic X-Type quote — it protects you from paying for parts that don't fit your actual car.
