- 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 ensure your vehicle doesn't overheat. And this cooling system relies 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 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 damage to your Nissan.
In time, the rubber that makes up the Radiator Coolant Hose (Upper) on your Nissan can get worn out. When this happens, the Radiator Coolant Hose (Upper) may become brittle and crack, allowing coolant to leak out. If too much 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.
Also, your Radiator Coolant Hose (Upper) can become bloated, meaning the hose swells. An engine overheating from low coolant can cause superheated coolant to pass through the Radiator Coolant Hose (Upper), making the rubber in the hose bloat and swell, likely causing additional damage and cracks to the 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 working with the coolant system, always ensure the coolant system and engine are completely cool, as the cooling system is pressurized, and super hot coolant may spray if something happens to the Radiator Coolant Hose (Upper).
When looking at the Radiator Coolant Hose (Upper), look for cracks, warping, dry-rotted areas, and swelling. Check for coolant fluid leaks 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 to see if the Low Coolant light is on or if the temperature gauge is showing the engine running too hot. Your owner's manual gives an overview of your vehicle's dashboard lights and what they mean.
