Ford EcoSport 2014-2017 Coolant Reservoir Hose Genuine CN118K276AE

The Ford EcoSport coolant reservoir hose, part number CN118K276AE, is a cooling system component designed to carry coolant between the expansion tank and the engine, helping maintain stable coolant circulation throughout the system. This part helps balance pressure, top up coolant as temperatures change, and keep the engine operating within the normal temperature range.

On the Ford EcoSport 2014-2017, the coolant hose works in sync with the radiator, water pump, thermostat, expansion tank, and other cooling pipes to keep coolant flowing continuously. As a result, the engine is cooled efficiently, the risk of overheating is reduced, and overall performance and internal engine component life are improved.

The genuine Ford hose is made from high-quality synthetic rubber combined with a pressure-reinforced layer, offering strong resistance to heat, pressure, and aging under demanding operating conditions. Both ends are precisely manufactured to the maker's standards, ensuring a tight fit, helping prevent coolant leaks, and delivering long-lasting durability.

After a period of use, a coolant hose can become hardened, cracked, swollen, or leak due to constant heat and pressure. When that happens, the cooling system can lose coolant, causing the engine to heat up quickly, trigger temperature warnings, or more seriously damage the head gasket and other internal engine parts. That is why timely inspection and replacement are essential for safe vehicle operation.

Product CN118K276AE is a genuine Ford part manufactured to strict OEM standards, delivering high durability, excellent heat resistance, and precise fitment on the Ford EcoSport.
