Mercedes GLC200 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 GLC200 uses a completely different engine family from the V8 M178 fitted to the GLC-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 GLC200ENGINE OPTIONS
Every GLC200 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR GLC200 ENGINE
We rebuild the engine your GLC200 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 GLC200 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 GLC200 ENGINES
Restoring your existing engine to full working condition rather than replacing it outright. Our rebuild service covers this.
Learn moreREMANUFACTURED GLC200 ENGINES
Built to original specification with updated components. That's consistent with what our rebuild service delivers on the M256.
Learn moreREPLACEMENT GLC200 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 GLC200 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 GLC200 ENGINE
The GLC200 has been part of the GLC-Class range since the model launched in 2015, spanning two generations under one badge. The X253 generation (2015–2022) uses the M274 — a 2.0-litre four-cylinder petrol engine shared across a wide range of Mercedes models of that era. From 2022, the X254-generation GLC200 switched to the M254, a newer 2.0-litre four-cylinder unit with mild-hybrid technology that delivers the same 255hp but with more torque (295 lb-ft vs the earlier 258 lb-ft). Knowing which one your car has matters, because the 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 GLC200 on the road.
MERCEDES GLC200 ENGINE CODES
M274 (X253, 2015–2022)
A 2.0-litre four-cylinder petrol fitted to the GLC200 from 2015 to 2022. No widely-reported specific issue has been independently confirmed for this engine in the GLC200 application, but we replace timing chains, bearings and gaskets as standard on every rebuild.
Check Your M274 GLC200M254 (X254, 2022–present)
The current 2.0-litre four-cylinder petrol with mild-hybrid technology, fitted from 2022. This is a different unit from the M274, with its own design features including an integrated starter-generator. No widely-reported specific issue has been independently confirmed for this engine in the GLC200 application, but we service it to the same high standard as our other GLC-Class rebuilds.
Check Your M254 GLC200MERCEDES GLC200 ENGINE COMPATIBILITY
Because the GLC200 spans two distinct engines across two generations, fitting the wrong replacement — or assuming an M274 part will work on an M254 car — risks a compatibility problem that's expensive to unpick. Before we quote or supply anything, we confirm:
Your exact engine code (M256) via registration or VIN
Your generation (R190)
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 GLC-Class quote — it protects you from paying for parts that don't fit your actual car.
MERCEDES GLC200 ENGINES BY YEAR
From the R190's launch in 2023, the GLC200 has used the M256 3.0-litre inline-six mild hybrid throughout. If you're unsure of your exact spec, we'll confirm it before you book.
The M256 has been fitted to every GLC200 since launch — if your registration year isn't listed above, get in touch and we'll confirm availability directly against your reg.
