- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan's cooling system is designed to keep the vehicle from overheating. And the cooling system depends on a working, quality Radiator Coolant Hose (Upper) to operate properly. As the coolant in your Nissan travels through the coolant system and radiator to you vehicle's engine, it has to go through a Radiator Coolant Hose (Upper). It's crucial that your Radiator Coolant Hose (Upper) is free from damage, leaks, cracks, or bloating that could cause more damage to your Nissan.
In time, the rubber that makes your Nissan's Radiator Coolant Hose (Upper) can wear out. If this happens, your Radiator Coolant Hose (Upper) can get brittle and crack, causing coolant to leak out. If enough coolant leaks out, your vehicle's engine may not receive enough coolant to control the engine's temperature, which could cause your Nissan to overheat. If overheating occurs, it could lead to added repairs and further damage to your vehicle.
Also, the Radiator Coolant Hose (Upper) may bloat, which means the hose swells up. 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 believe a Radiator Coolant Hose (Upper) on your Nissan needs to be exchanged, a visual inspection is often a good place to start. When dealing with the coolant system, always make sure the engine and coolant system are completely cooled down, as the cooling system is pressurized, and heated coolant can spray if the Radiator Coolant Hose (Upper) becomes compromised.
When checking out 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.
Additionally, 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 provides an overview of the different dashboard lights and their meanings.
