- 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 prevent the engine from overheating. And your vehicle's cooling system relies on a functioning, quality Radiator Coolant Hose (Upper) to operate how it's supposed to. 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 important your Radiator Coolant Hose (Upper) is free from leaks, cracks, or bloating that could cause more damage to your Nissan.
Eventually, the rubber that makes up your Nissan's Radiator Coolant Hose (Upper) can get worn out. If this happens, the Radiator Coolant Hose (Upper) may become brittle and crack, causing a coolant leak. If enough coolant leaks out, the engine might not receive enough coolant to maintain a safe engine temperature, potentially causing your Nissan to overheat. If overheating occurs, it could lead to repairs and damage your vehicle.
Also, the Radiator Coolant Hose (Upper) can get bloated, meaning the hose bulges out or swells in some places. 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, potentially causing further cracks and damage to your vehicle's Radiator Coolant Hose (Upper).
If you think your Nissan's Radiator Coolant Hose (Upper) needs replacing, it's good to start with a visual inspection. When checking the coolant system, always make sure the engine and coolant system are completely cool, as the 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 dry-rot, cracks, swelling, or 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 showing the engine running too hot. Your owner's manual gives an overview of dashboard lights and their meanings.
