Expansion Tank For Mercedes W246, W176, C117, X156 With M270 And OM607 Engines

The Frey Auto Coolant Reservoir designed specifically for Mercedes-Benz (B-Class) W246, (A-Class) W176, (CLA-Class) C117 and (GLA-Class) X156 models with M270 and OM607 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: 2465000049.
