Mercedes Cylinder Head Gasket - Genuine Mercedes 6420165120

Product Information

A cylinder head gasket seals the cylinder head to the engine block. A head gasket performs a few important functions. For starters, a head gasket seals the combustion chamber of the engine allowing the engine to create proper compression. In addition, head gaskets seal oil and coolant passages between the cylinder head and engine block which prevents fluids from mixing or entering the combustion chamber.

• Overheating engine
• Low cylinder compression
• External oil or coolant leak
• White smoke from exhaust
• Bubbles in radiator or expansion tank
• White/milky engine oil

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
