The upper coolant hose is a crucial component in the engine’s cooling system of a vehicle. It is typically made of rubber or reinforced silicone to withstand the heat and pressure in the engine bay. The upper coolant hose connects the engine’s coolant outlet to the radiator, allowing the heated coolant to flow from the engine to the radiator for cooling.

The cooling system in a car is essential for maintaining the engine’s operating temperature within a safe range. The upper coolant hose, along with other components like the radiator, thermostat, and lower coolant hose, plays a key role in ensuring proper circulation of coolant to dissipate the heat generated during engine operation.

The part number “2225014191” appears to be a specific identifier for this particular upper coolant hose in Mercedes-Benz vehicles.
