Your Nissans cooling system is designed to keep the vehicle from overheating. And your vehicles cooling system relies on a quality, functioning Radiator Coolant Hose (Upper) to work correctly. As the coolant in your Nissan Altima passes through the radiator and coolant system to the engine, it passes through a Radiator Coolant Hose (Upper). Its crucial that your Radiator Coolant Hose (Upper) is free from cracks, bloating, or leaks that could cause more damage to your Nissan.
Eventually, the rubber that makes up the Radiator Coolant Hose (Upper) on your Nissan Altima can get old and wear out. If this happens, the Radiator Coolant Hose (Upper) can become brittle and crack, causing coolant to leak out. If enough coolant leaks out, your vehicles engine may not receive enough coolant to keep the engine temperature under control, potentially causing your Nissan to overheat. If overheating occurs, it could lead to repairs and damage your vehicle.
In addition, 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), causing the rubber material to swell and bloat, possibly causing additional cracks and damage to your Radiator Coolant Hose (Upper).
If you feel the Radiator Coolant Hose (Upper) on your vehicle needs replacing, its good to start with a visual inspection. When checking the coolant system, always ensure the vehicles engine and coolant system are completely cool, as the cooling system is under pressure, and super hot coolant may spray if the Radiator Coolant Hose (Upper) breaks.
When inspecting your Radiator Coolant Hose (Upper), look for cracks, warping, dry-rotted areas, and swelling. Check the ground underneath the vehicle for coolant leaks, specifically where the Radiator Coolant Hose (Upper) attaches to the vehicle.
In addition, check the dashboard if you feel you have a bad Radiator Coolant Hose (Upper). Check if the Low Coolant light is illuminated or if the temperature gauge is showing the engine running too hot. Your owners manual has an overview of the different dashboard lights and their meanings.
