The coolant upper 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’s inlet, allowing the heated coolant to flow from the engine to the radiator for cooling.

Key features of a typical coolant upper hose include:

Material: The hose is constructed from materials that can withstand the high temperatures and pressures in the engine compartment.

Flexibility: The hose is designed to be flexible to allow for engine movement and to facilitate easy installation.

Reinforcement: Many coolant hoses have reinforcement layers to enhance strength and durability.

Connector Ends: The hose typically has connector ends that are designed to securely attach to the engine coolant outlet and the radiator’s inlet.

OEM Standards: Genuine coolant hoses from Mercedes-Benz are designed to meet the original equipment manufacturer (OEM) standards, ensuring compatibility and performance.
