About the Mercedes-Benz C300 M274
The W205 C300 runs the M274 2.0L turbocharged four-cylinder, paired with a 7-speed automatic in its first year and a 9-speed automatic after that.
Fitment notes
4MATIC and RWD cars use different mounting and oil pan hardware. The listing covers the 2015-2020 model years, but options such as drivetrain, emissions package and trim can change the correct part within a single year. That is why we confirm every order with your VIN and the engine code before you pay.
- Share your 17-character VIN with your quote request.
- If possible, send a photo of the engine code on the block or the emissions label.
What is included
Used engines are typically sold as a long block or as a complete assembly with the intake and some accessories. Your quote states exactly what is attached, such as the intake manifold, exhaust manifolds, sensors, alternator or starter, so you know what to transfer from your old engine.
Before you install
Before installation, replace the oil and filter, coolant, spark plugs and thermostat, and inspect the radiator and cooling fans. Prime the oil system before first start and check for leaks during the first run.
Warranty, shipping and payment
Your written quote lists the warranty for this part, the delivery method and both payment stages. The first stage covers verification and freight coordination.
