Jaguar XJ 5.0 V8 Supercharged Timing Chain Tensioner & Water Pump
If your XJ is a 2009-2019 model with the AJ133S supercharged V8 - that's the X351 generation - timing chain tensioner and guide wear is a well-documented pattern on this engine, backed by a US class-action lawsuit covering this exact engine across multiple JLR models. The hardened steel tensioner piston wears an aluminium guide button over time, which can fail with no warning. We replace the timing chain, tensioners and guides as standard on every AJ133S rebuild.
The water pump on these engines also shows bearing and seal failure, sometimes under 20,000 miles, due to coolant ingress - we replace it as standard too.
Source: verified via multiple independent sources (kmotors.co.uk, rrsport.co.uk lawsuit reference, TopSpeed reliability ranking), per VRF-jaguar-xj.md. Timing chain tensioner design flaw and water pump failure confirmed for AJ133/AJ133S engines, particularly 2012-2014 models, per X351 row.
Jaguar XJ 5.0 V8 SuperchargedENGINE OPTIONS
Every XJ 5.0 V8 Supercharged is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XJ 5.0 V8 SUPERCHARGED ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XJ already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chain, tensioners, guides and water pump) 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 XJ owners choose, and it's the one we'd recommend for most situations.
From £5,500RECONDITIONED XJ 5.0 V8 SUPERCHARGED 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 XJ 5.0 V8 SUPERCHARGED 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 XJ 5.0 V8 SUPERCHARGED 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 AJ133S.
Learn moreREPLACEMENT XJ 5.0 V8 SUPERCHARGED 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 XJ 5.0 V8 SUPERCHARGED 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.

ABOUT THE Jaguar XJ 5.0 V8 Supercharged ENGINE

The XJ 5.0 V8 Supercharged uses the AJ133S - a 5.0-litre supercharged V8 petrol engine. It was fitted from 2009 to 2019 across the X351 generation, representing the flagship performance option in the XJ range alongside the naturally aspirated 5.0 V8 and the supercharged V6 models. The AJ133S is part of Jaguar's Gen III AJ-V8 family and shares the same timing chain tensioner design pattern as other JLR vehicles of this era.
