- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan relies on the cooling system to ensure your vehicle doesn't overheat. And your vehicle's cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to operate properly. As the coolant in your Nissan passes through the radiator and coolant system to the engine, it passes through a Radiator Coolant Hose (Lower). It's important your Radiator Coolant Hose (Lower) is free from cracks, bloating, or leaks that may cause further damage to your vehicle.
Eventually, the rubber in your vehicle's Radiator Coolant Hose (Lower) can wear out. When this occurs, the Radiator Coolant Hose (Lower) can become brittle and crack, allowing coolant to leak out. If an excess amount of coolant leaks out, the engine may not get 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 (Lower) may bloat, which means the hose swells up. If low coolant causes the engine to overheat, it could cause intensely heated coolant to pass through the hose, which can make the rubber swell and bloat, likely causing additional damage and cracks to your vehicle's Radiator Coolant Hose (Lower).
If you believe the Radiator Coolant Hose (Lower) on your vehicle needs to be replaced, it's good to start with a visual inspection. When working with the coolant system, always ensure the vehicle's engine and coolant system are cooled down completely, as the cooling system is pressurized, and extremely hot coolant fluid can spray if the Radiator Coolant Hose (Lower) breaks.
When inspecting your Radiator Coolant Hose (Lower), look for swelling, cracks, dry-rot, and warping. Check the ground underneath the vehicle for coolant leaks, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.
In addition, look on your dashboard if you think your Radiator Coolant Hose (Lower) is bad. Check to see if the Low Coolant light is on or if the temperature gauge is in the red, meaning your engine is running too hot. Your Nissan owner's manual has an overview of your vehicle's dashboard lights and what they mean.
