4. Product Description

This replacement engine coolant pipe is intended for compatible Mercedes-Benz vehicles equipped with the M264 engine. It provides a coolant passage within the engine cooling system and is intended to replace a matching pipe that is cracked, worn, damaged, or leaking.

Correct fitment depends on the original part number, engine configuration, pipe routing, connection layout, and mounting design. The supplied information does not establish compatibility with every vehicle sharing the same model name or displacement. Compare the replacement with the original component and verify the OE number before installation.

5. Product Specifications

6. Function and Replacement Considerations

The coolant pipe carries engine coolant between connected components in the cooling system. A damaged or leaking pipe may contribute to coolant loss. However, coolant loss or engine overheating can have other causes, and replacing this pipe does not guarantee that every cooling-system problem will be resolved.

Before installation, compare the pipe bends, overall shape, connection ports, and mounting points with the removed part. Do not assume that a similar-looking pipe for a different engine family is interchangeable.

7. Package Includes

• 1 x Engine Coolant Pipe

Hoses, clamps, seals, thermostat, sensors, installation hardware, and instructions are not included unless explicitly shown or stated in the actual package contents.

8. Before Purchase / Fitment Check

Please check the following before placing your order:

• Verify that the original part number matches 2642008600 or A2642008600.
• Confirm that your vehicle uses the M264 engine, not merely a 2.0L engine.
• Compare the pipe shape, routing, connection ports, and mounting points with your original component and the listing photos.
• Confirm the exact model year and vehicle configuration. For a 2022 C300 or 2023 GLC300, verify the engine code and OE number carefully because North American model-year transitions may involve the M254 engine family.
• If the OE number, engine code, or physical connection layout differs, contact the seller for verification before ordering.

9. Important Fitment Note

Vehicle model and year alone do not guarantee compatibility. This listing is intended for matching M264 applications with the correct reference part number. Similar-looking coolant pipes for other engine families or configurations may use different connections or mounting designs. Please verify the original OE number, engine code, and physical part configuration before purchase to help avoid ordering an incompatible replacement.
