Your Nissans cooling system is designed to ensure your vehicle doesnt overheat. And your vehicles cooling system relies on a quality, functioning Radiator Coolant Hose (Upper) to operate properly. As your vehicles coolant fluid travels through the coolant system and radiator to the engine, it travels through a Radiator Coolant Hose (Upper). Its important your Radiator Coolant Hose (Upper) is free from cracks, bloating, or leaks that may cause further damage to your vehicle.

Eventually, the rubber in your Nissans Radiator Coolant Hose (Upper) can get old and wear out. When this occurs, the Radiator Coolant Hose (Upper) can become brittle and crack, causing a coolant leak. If an excess amount of coolant leaks out, your vehicles engine may not receive enough coolant to maintain a safe engine temperature, which may cause overheating in your Nissan. An overheated engine could lead to repairs and damage your vehicle.

Additionally, the Radiator Coolant Hose (Upper) can get bloated, which means the hose swells up. An engine overheating from low coolant can cause superheated coolant to pass through the Radiator Coolant Hose (Upper), making the rubber in the hose bloat and swell, possibly causing additional cracks and damage to your Radiator Coolant Hose (Upper).

If you think your Nissans Radiator Coolant Hose (Upper) needs to be exchanged, a great place to start is a visual inspection. When checking the coolant system, always ensure the coolant system and engine are completely cooled down, as the cooling system is pressurized, and extremely hot coolant fluid 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. Check for coolant fluid leaks underneath the vehicle, specifically where the Radiator Coolant Hose (Upper) attaches to the vehicle.

In addition, look at your dashboard if you suspect a bad Radiator Coolant Hose (Upper). Look for a Low Coolant light or if the temperature gauge is displaying that your engine is running hot. Your Nissan owners manual gives an overview of your vehicles dashboard lights and what they mean.
