Land Rover Range Rover P440e Oil Leaks & Coolant System Wear (AJ300 I6)
The AJ300 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 AJ300 V6. We replace timing chains, bearings, water pump and gaskets as standard on every AJ300 rebuild.
Because the Range Rover P440e uses a completely different engine family from the V8 M178 fitted to the Range Rover 63 and GT 63 S, parts and rebuild specifications don't cross over between them.
Source: Established AJ300 specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.

Land Rover Range Rover P440eENGINE OPTIONS
Every Range Rover P440e is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR RANGE ROVER P440E ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Range Rover P440e already has instead — strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings and gaskets) 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 Range Rover owners choose, and it's the one we'd recommend for most situations.
RECONDITIONED RANGE ROVER P440E 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.
REFURBISHED RANGE ROVER P440E 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.
REMANUFACTURED RANGE ROVER P440E 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 AJ300.
REPLACEMENT RANGE ROVER P440E 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.
USED RANGE ROVER P440E 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?

ABOUT THE Land Rover Range Rover P440e ENGINE

The Range Rover P440e is part of the L460 generation, introduced in 2022 as a plug-in hybrid variant of the flagship luxury SUV. It uses the AJ300 — a 3.0-litre turbocharged inline-six petrol engine — paired with a 105kW electric motor, delivering 440PS combined output. The P440e sits alongside the P460e, P510e and P550e PHEV badges, all sharing the same AJ300 engine family with different power output tunes. The Range Rover P440e is a current variant and remains in production as of 2026.
We continue to rebuild and replace AJ300 engines for every Range Rover P440e on the road.

The AJ300 engine family is shared across all four PHEV badges — P440e, P460e, P510e and P550e — with output varying by tune. Check Your AJ300 Range Rover P440e → [link to quote form]
