Expansion Tank For Mercedes W205, S205, X253 With M274, OM651, M264, M276 And M177 Engine

The Frey Auto Coolant Reservoir designed specifically for Mercedes-Benz (C-Class) W205, S205 and (GLC-Class) X253 models with M274, OM651, M264, M276 and M177 engines. As the engine runs and the coolant temperature rises, the coolant expands due to heat. Without an expansion tank, this increase in pressure could damage hoses, the radiator, or the engine itself.The expansion tank acts as an overflow reservoir. It temporarily stores the excess coolant, keeping the system sealed and under proper pressure. Manufactured using heat-resistant plastic, coolant level sensor and pressure-release cap (rated between 1.2–1.5 bar) which raises the boiling point of the coolant, allowing the engine to operate more efficiently without boiling over. Engineered with precision to meet OEM standards as this product is ISO9001 certified. Replacement Part for: 2055000049. Suitable to fit the following vehicles: W205/S205 – (2014-2021) C180 C200 C220d C250 C300 C350e C400 C450 C63 AMG X253 – (2015-2022) GLC200 GLC220d GLC250 GLC300 GLC43 AMG
