Avoid Engine Overheating with a Genuine Car Radiator Hose

Your car generates a massive amount of heat that needs to be cooled to avoid costly repairs. The radiator is part of this process as it’s responsible for storing your engine coolant, otherwise known as antifreeze. A special thermostat controls your radiator and monitors your engine’s temperature. When it detects the engine has reached a certain heat threshold, it will release the antifreeze.

This is where radiator hoses come in. It’s the passageway that the coolant uses to reach the engine. Once it does, it returns to the radiator to be recooled. Radiator hoses come in two: the inlet and outlet hose.

The outlet hose transports the antifreeze from the radiator to the engine to cool it off. Meanwhile, the inlet hose is responsible for taking the hot antifreeze from the engine, returning it to the radiator, and using it again once the thermostat detects another temperature rise. 

You might want to change your radiator hose every five years or every 60,000 miles, depending on your car model. This will ensure that the cooling system is at an optimal level and your engine doesn’t suffer overheating. You should also watch out for signs like poor air conditioning output, leaking coolant, or steam coming out from the engine compartment. When this happens, you should immediately replace your radiator hose to avoid costly engine repairs.
