- 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 ensure your vehicle doesn't overheat. And your vehicle's cooling system relies on a working, quality Radiator Coolant Hose (Upper) to operate how it's supposed to. As the coolant fluid in your Nissan passes through the radiator and coolant system to the engine, it passes through a Radiator Coolant Hose (Upper). It's essential that the Radiator Coolant Hose (Upper) remain free from damage, leaks, cracks, or bloating that may cause further damage to your vehicle.
Eventually, the rubber that makes 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, causing coolant to leak out. If an excess amount of coolant leaks out, the engine might not receive enough coolant to keep the engine temperature under control, which could cause your Nissan to overheat. If the engine overheats, it may lead to repairs and damage your vehicle.
Also, your Radiator Coolant Hose (Upper) can become 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), which can make the rubber swell and bloat, likely causing additional damage and cracks to the Radiator Coolant Hose (Upper).
If you believe your Nissan's Radiator Coolant Hose (Upper) needs to be replaced, it's good to start with a visual inspection. When dealing with the coolant system, always ensure the coolant system and engine are completely cool, as the cooling system is under pressure, and heated coolant can spray if the Radiator Coolant Hose (Upper) breaks.
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, specifically underneath where the Radiator Coolant Hose (Upper) is located on the vehicle.
Additionally, look at your dashboard if you suspect a bad Radiator Coolant Hose (Upper). 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 dashboard lights and their meanings.
