Your INFINITI depends on its cooling system to prevent the engine from overheating. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Upper) to work properly. As your vehicle's coolant fluid travels through the coolant system and radiator to you vehicle's 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 more damage to your INFINITI.
Over time, the rubber that makes the Radiator Coolant Hose (Upper) on your INFINITI can get worn out. When this occurs, the Radiator Coolant Hose (Upper) may become brittle and crack, allowing coolant to leak out. If an excess amount of coolant leaks out, the engine might not receive enough coolant to control the engine's temperature, which may cause overheating in your INFINITI. If overheating occurs, it could lead to additional repairs and even damage to the vehicle.
Additionally, the Radiator Coolant Hose (Upper) may bloat, meaning the hose bulges out or swells in some places. 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 feel your INFINITI's Radiator Coolant Hose (Upper) needs replacing, a visual inspection is often a good place to start. When dealing with the coolant system, always ensure the coolant system and engine are completely cool, as the entire cooling system is pressurized, and heated coolant can spray if the Radiator Coolant Hose (Upper) breaks.
When inspecting your Radiator Coolant Hose (Upper), look for swelling, cracks, dry-rot, and warping. Check for coolant fluid leaks underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Upper) is located on the vehicle.
Additionally, look on your dashboard if you think your Radiator Coolant Hose (Upper) is bad. Check if the Low Coolant light is illuminated or if the temperature gauge is displaying that your engine is running hot. Your owner's manual has an overview of your vehicle's dashboard lights and what they mean.
