Every engine is inspected, grade-rated, and backed by our 4-Year / 40,000-Mile warranty.

About the 2015 Mercedes-Benz GLK250 Engine

The 2015 GLK250 is powered by Mercedes-Benz's 2.0-liter turbocharged inline-4 petrol engine (engine code: M274), producing 211 horsepower and 258 lb-ft of torque. This engine was paired exclusively with Mercedes-Benz's 7-speed 7G-Tronic automatic transmission and 4MATIC all-wheel drive on the GLK250 trim. It replaced the older 3.5L V6 used in previous GLK generations, offering better fuel economy while maintaining strong performance.

The M274 engine family uses direct injection, variable valve timing on both camshafts (CAMTRONIC), and a twin-scroll turbocharger. While generally reliable, high-mileage M274 units can develop issues that make a low-mileage replacement the most cost-effective repair option.

Common Reasons GLK250 Owners Need an Engine Replacement

  • Timing chain wear—The M274's plastic timing chain guides can wear at higher mileages, causing rattling on cold starts and eventually chain stretch. This is one of the most common reasons 2015 GLK250 owners seek an engine replacement
  • Excessive oil consumption—Some M274 engines develop piston ring wear that causes oil burning, visible as blue smoke from the exhaust and low oil level warnings
  • Turbocharger failure — The twin-scroll turbo is oil-fed and can fail if oil changes are neglected. Turbo failure can send debris into the engine and require a full replacement
  • Coolant leak into cylinders—Head gasket or coolant seal failures can cause coolant to enter the combustion chamber, resulting in white exhaust smoke and hydrolocking
  • High mileage general wear—GLK250 engines with 150,000+ miles often need replacement due to overall internal wear that makes repair less economical than a quality used unit

Why a Low-Mileage Used Engine Is the Best Solution

A new Mercedes-Benz M274 long block from the dealer costs $8,000–$14,000 before labour. A quality 2015 GLK250 engine from Moon Auto Parts with verified low mileage costs a fraction of that comes with our 4-Year warranty, so you're protected against any issues after installation.

Our current Grade A unit at 60,904 miles represents a nearly new engine relative to the vehicle's lifespan. With proper oil changes and maintenance, you can expect 100,000+ additional miles from this unit once installed.
