Your Nissan relies on the cooling system to keep the vehicle from overheating. And this cooling system relies on a quality, functioning Radiator Coolant Hose (Upper) to operate properly. As the coolant in your Nissan goes through the radiator and coolant system to the engine, it travels through a Radiator Coolant Hose (Upper). Its crucial that your Radiator Coolant Hose (Upper) is free from damage, 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 wear out. If this happens, the Radiator Coolant Hose (Upper) can become brittle and crack, causing coolant to leak out. If enough coolant leaks out, your vehicles engine may not receive enough coolant to keep the engine temperature under control, potentially causing your Nissan to overheat. If the engine overheats, it may lead to repairs and damage your vehicle.
Also, your Radiator Coolant Hose (Upper) can become bloated, meaning the hose swells. An overheating engine due to low coolant may cause extremely hot coolant to travel through the Radiator Coolant Hose (Upper), making the rubber in the hose bloat and swell, potentially causing further cracks and damage to your Radiator Coolant Hose (Upper).
If you believe the Radiator Coolant Hose (Upper) on your vehicle needs to be replaced, a great place to start is a visual inspection. When checking the coolant system, always ensure the vehicles engine and coolant system are completely cooled down, as the cooling system is under pressure, 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. Check for coolant fluid leaks 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. Look for a Low Coolant light or if the temperature gauge is showing the engine running too hot. Your Nissan owners manual gives an overview of the different dashboard lights and their meanings.
