- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan relies on the cooling system to keep the vehicle from overheating. And this cooling system relies on a working, quality Radiator Coolant Hose (Upper) to operate how it's supposed to. As the coolant in your Nissan goes through the radiator and coolant system to your engine, it travels through a Radiator Coolant Hose (Upper). It's crucial that your Radiator Coolant Hose (Upper) is free from leaks, cracks, or bloating that could cause damage to your Nissan.
In time, the rubber that makes up your vehicle's Radiator Coolant Hose (Upper) can get worn out. When this occurs, the Radiator Coolant Hose (Upper) may become brittle and crack, causing a coolant leak. If an excess amount of coolant leaks out, the engine may not get 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) may bloat, meaning the hose swells. If low coolant causes the engine to overheat, it may cause extremely hot coolant to travel through the Radiator Coolant Hose (Upper), which can make the rubber swell and bloat, possibly causing additional cracks and damage to your vehicle's Radiator Coolant Hose (Upper).
If you think a Radiator Coolant Hose (Upper) on your Nissan needs to be exchanged, a great place to start is a visual inspection. When dealing with the coolant system, always make sure the engine and coolant system are cooled down completely, as the entire cooling system is pressurized, and heated coolant can spray if the Radiator Coolant Hose (Upper) breaks.
When looking at the Radiator Coolant Hose (Upper), look for dry-rot, cracks, swelling, or warping. Look for coolant leaks on the ground underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Upper) is located on the vehicle.
In addition, check the dashboard if you feel you have a bad Radiator Coolant Hose (Upper). Check if the Low Coolant light is illuminated or if the temperature gauge is in the red, meaning your engine is running too hot. Your Nissan owner's manual gives an overview of your vehicle's dashboard lights and what they mean.
