- 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 prevent the engine from overheating. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Upper) to operate how it's supposed to. As the coolant fluid in your Nissan passes through the radiator and coolant system to you vehicle's engine, it travels through a Radiator Coolant Hose (Upper). It's essential that the Radiator Coolant Hose (Upper) remain free from cracks, bloating, or leaks that could cause damage to your Nissan.
Eventually, the rubber in the Radiator Coolant Hose (Upper) on your Nissan can get worn out. When this occurs, the Radiator Coolant Hose (Upper) may become brittle and crack, causing coolant to leak out. If too much coolant leaks out, the engine may not get enough coolant to control the engine's temperature, potentially causing your Nissan to overheat. An overheated engine could lead to additional repairs and even damage to the vehicle.
Additionally, the Radiator Coolant Hose (Upper) may bloat, meaning the hose swells. An overheating engine due to low coolant could cause intensely heated coolant to pass through the hose, which can make the rubber swell and bloat, possibly causing additional cracks and damage to the Radiator Coolant Hose (Upper).
If you believe the Radiator Coolant Hose (Upper) on your vehicle needs replacing, it's good to start with a visual inspection. When working with the coolant system, always make sure the engine and coolant system are completely cool, as the entire cooling system is pressurized, and super hot coolant may spray if the Radiator Coolant Hose (Upper) becomes compromised.
When checking out the Radiator Coolant Hose (Upper), look for dry-rot, cracks, swelling, or warping. Check the ground underneath the vehicle for coolant leaks, specifically where the Radiator Coolant Hose (Upper) attaches to the vehicle.
In addition, 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 displaying that your engine is running hot. Your Nissan owner's manual has an overview of your vehicle's dashboard lights and what they mean.
