Your Nissan depends on its cooling system to prevent the engine from overheating. And this cooling system relies on a functioning, quality Radiator Coolant Hose (Upper) to work properly. As your vehicles coolant fluid travels through the coolant system and radiator to your vehicles engine, it passes through a Radiator Coolant Hose (Upper). Its essential that the Radiator Coolant Hose (Upper) remain free from leaks, cracks, or bloating that could cause more damage to your Nissan.
Eventually, the rubber that makes up your Nissans Radiator Coolant Hose (Upper) can get worn out. When this occurs, the Radiator Coolant Hose (Upper) can become brittle and crack, allowing coolant to leak out. If an excess amount of coolant leaks out, your vehicles engine may not receive enough coolant to maintain a safe engine temperature, potentially causing your Nissan to overheat. If overheating occurs, it could lead to added repairs and further damage to your vehicle.
Additionally, the Radiator Coolant Hose (Upper) can get bloated, meaning the hose bulges out or swells in some places. If low coolant causes the engine to overheat, it can cause superheated coolant to pass through the Radiator Coolant Hose (Upper), making the rubber in the hose bloat and swell, potentially causing further cracks and damage to the Radiator Coolant Hose (Upper).
If you believe a Radiator Coolant Hose (Upper) on your Nissan needs to be replaced, a great place to start is a visual inspection. When working with the coolant system, always ensure the vehicles engine and coolant system are completely cool, as the entire cooling system is pressurized, and heated coolant can spray if the Radiator Coolant Hose (Upper) becomes compromised.
When looking at the Radiator Coolant Hose (Upper), look for swelling, cracks, dry-rot, and warping. Look for coolant leaks on the ground underneath the vehicle, especially where your Radiator Coolant Hose (Upper) is attached to the vehicle.
Also, look on your dashboard if you think your Radiator Coolant Hose (Upper) is bad. Check to see if the Low Coolant light is on or if the temperature gauge is in the red, meaning your engine is running too hot. Your owners manual gives an overview of your vehicles dashboard lights and what they mean.
