Mercedes-Benz Genuine Coolant Expansion Reservoir Tank (Part Number: 1772000285):

Functionality: The coolant expansion reservoir tank is a crucial component of the vehicle’s cooling system. It serves as a storage and overflow container for the engine coolant. As the engine heats up, coolant expands, and excess coolant is directed to the expansion tank. Conversely, when the engine cools down, coolant is drawn back into the system from the reservoir.

Material: Genuine Mercedes-Benz parts are typically constructed from high-quality materials that are compatible with engine coolant and resistant to temperature variations. The material used ensures durability and longevity.

OEM Standards: Being a genuine Mercedes-Benz part, this coolant expansion reservoir tank is designed to meet or exceed the original equipment manufacturer (OEM) standards. This ensures compatibility with the specific cooling system requirements of your Mercedes-Benz model.

Compatibility: The part number 1772000285 is specific to Mercedes-Benz and is intended for use on certain models. It’s crucial to confirm compatibility with your specific Mercedes-Benz model and year to ensure proper fitment.

Level Indicator: Some expansion tanks include a level indicator to allow for easy visual inspection of the coolant level. This helps in monitoring the coolant level without opening the reservoir.

Installation: Genuine parts are generally designed for straightforward installation, often using existing mounting points in the vehicle’s engine bay. However, it’s important to follow the manufacturer’s guidelines for proper installation.

Cooling System Maintenance: Regular inspection of the coolant level and the condition of the expansion tank is important for maintaining the proper functioning of the cooling system. Periodic coolant flushes and system checks are part of routine maintenance.
