- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan depends on its cooling system to keep the vehicle from overheating. And the cooling system depends on a working, 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 passes through a Radiator Coolant Hose (Upper). It's important your Radiator Coolant Hose (Upper) is free from leaks, cracks, or bloating that could cause more damage to your Nissan.
In time, the rubber in your Nissan's Radiator Coolant Hose (Upper) can get old and wear out. When this happens, your Radiator Coolant Hose (Upper) can get brittle and crack, allowing coolant to leak out. If an excess amount of coolant leaks out, the engine might not receive enough coolant to maintain a safe engine temperature, which may cause overheating in your Nissan. If the engine overheats, it may lead to additional repairs and even damage to the vehicle.
Additionally, your Radiator Coolant Hose (Upper) can become bloated, 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, making the rubber in the hose bloat and swell, likely causing additional damage and cracks to your vehicle's Radiator Coolant Hose (Upper).
If you feel a Radiator Coolant Hose (Upper) on your Nissan needs replacing, it's good to start with a visual inspection. When checking the coolant system, always ensure the coolant system and engine are cooled down completely, as the cooling system is under pressure, and heated coolant can spray if something happens to the Radiator Coolant Hose (Upper).
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.
In addition, 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 Nissan owner's manual has an overview of the different dashboard lights and their meanings.
