Your Nissans cooling system is designed to ensure your vehicle doesnt overheat. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Lower) to work properly. As the coolant fluid in your Nissan goes through the radiator and coolant system to your vehicles engine, it has to go through a Radiator Coolant Hose (Lower). Its essential that the Radiator Coolant Hose (Lower) remain free from cracks, bloating, or leaks that could cause more damage to your Nissan.
Over time, the rubber that makes up your Nissans Radiator Coolant Hose (Lower) can get worn out. If this happens, the Radiator Coolant Hose (Lower) may become brittle and crack, allowing 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.
Additionally, your Radiator Coolant Hose (Lower) can become bloated, meaning the hose swells. An engine overheating from low coolant may cause extremely hot coolant to travel through the Radiator Coolant Hose (Lower), making the rubber in the hose bloat and swell, potentially causing further cracks and damage to your Radiator Coolant Hose (Lower).
If you think a Radiator Coolant Hose (Lower) on your Nissan needs replacing, its good to start with a visual inspection. When dealing with the coolant system, always ensure the coolant system and engine are cooled down completely, as the entire cooling system is pressurized, and extremely hot coolant fluid can spray if something happens to the Radiator Coolant Hose (Lower).
When looking at the Radiator Coolant Hose (Lower), look for dry-rot, cracks, swelling, or warping. Check the ground underneath the vehicle for coolant leaks, specifically where the Radiator Coolant Hose (Lower) attaches to the vehicle.
Also, check the dashboard if you feel you have a bad Radiator Coolant Hose (Lower). Check if the Low Coolant light is illuminated or if the temperature gauge is in the red, meaning your engine is running too hot. Your owners manual has an overview of the different dashboard lights and their meanings.
