Mercedes GLE450 Oil Leaks & Coolant System Wear (M256 I6)
The M256 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 M276 V6. We replace timing chains, bearings, water pump and gaskets as standard on every M256 rebuild.
Because the GLE450 uses a completely different engine family from the V8 M178 fitted to the GLE-Class 63 and GT 63 S, parts and rebuild specifications don't cross over between them.
Source: Established M256 specialist pattern — timing chain, bearing and gasket wear across integrated-starter-generator inline-six units.

Mercedes GLE450ENGINE OPTIONS
Every GLE450 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR GLE450 ENGINE
We rebuild the engine your GLE450 already has instead of selling you a used engine of unknown history — strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings, water pump, gaskets) with updated OEM parts. Near-new performance with a 12-month unlimited-mileage warranty.
From £3,200RECONDITIONED GLE450 ENGINES
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 GLE450 ENGINES
Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.
Learn moreREMANUFACTURED GLE450 ENGINES
Built to original specification with updated components. That's consistent with what our rebuild service delivers on the M256.
Learn moreREPLACEMENT GLE450 ENGINES
If your existing engine is beyond economical repair, we offer complete engine replacement and fitting – sourced and fitted by our team, with the same 12-month warranty.
Learn moreUSED GLE450 ENGINES
Matched low-mileage used engines for when time is critical. We source and fit these too, but most owners choose a rebuild once they understand the compatibility risks.

ABOUT THE MERCEDES GLE450 ENGINE

The GLE450 has been part of the GLE-Class range since 2015. Earlier W166-generation cars use the M276 — a 3.0-litre V6 petrol. From 2019, the V167-generation GLE450 switched to the M256, a newer 3.0-litre inline-six petrol with mild hybrid technology — a different unit entirely, not an evolution of the M276. Knowing which one your car has matters, because the engine architecture, components, and rebuild specifics differ between them — which is exactly why we confirm your exact engine by registration before quoting.
We continue to rebuild and replace M256 engines for every GLE450 on the road.
MERCEDES GLE450 ENGINE CODES

M256 (R190, 2023–present)
A 3.0-litre inline-six petrol mild-hybrid engine fitted to the GLE450 from 2023 to present. The M256 features an integrated starter-generator (ISG) and electric auxiliary compressor, making it a more modern and efficient design than the older M276 V6. We replace timing chains, bearings, water pump and gaskets as standard on every M256 rebuild.
Check Your M256 GLE450MERCEDES GLE450 ENGINE COMPATIBILITY

Because the GLE450 spans two distinct engines across two generations, fitting the wrong replacement — or assuming an M276 part will work on an M256 car — risks a compatibility problem that's expensive to unpick. Before we quote or supply anything, we confirm: - Your exact engine code (M276 or M256) via registration or VIN - Your generation (W166 or V167) - Drivetrain and ancillary specification - Any electronics or ECU considerations specific to your exact build

Any electronics or ECU considerations specific to your exact build
This is why we always start with your registration rather than a generic GLE-Class quote — it protects you from paying for parts that don't fit your actual car.
