- 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 functioning, quality Radiator Coolant Hose (Upper) to work properly. As your vehicle's coolant fluid goes through the radiator and coolant system to you vehicle's engine, it has to go 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 that makes up your vehicle's Radiator Coolant Hose (Upper) can get worn out. When this occurs, your Radiator Coolant Hose (Upper) can get brittle and crack, allowing coolant to leak out. If too much coolant leaks out, your vehicle's engine may not receive enough coolant to keep the engine temperature under control, which may cause overheating in your Nissan. If overheating occurs, it could lead to added repairs and further damage to your vehicle.
Additionally, the Radiator Coolant Hose (Upper) can get bloated, which means the hose swells up. An overheating engine due to low coolant could cause intensely heated coolant to pass through the hose, causing the rubber material to 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 replacing, a visual inspection is often a good place to start. When checking the coolant system, always ensure the coolant system and engine are cooled down completely, as the entire 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.
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 displaying that your engine is running hot. Your Nissan owner's manual gives an overview of dashboard lights and their meanings.
