- 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 keep the vehicle from overheating. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Lower) to work properly. As your vehicle's coolant fluid travels through the coolant system and radiator to the engine, it travels through a Radiator Coolant Hose (Lower). It's essential that the Radiator Coolant Hose (Lower) remain free from leaks, cracks, or bloating that could cause damage to your Nissan.
In time, the rubber that makes up your vehicle's Radiator Coolant Hose (Lower) can wear out. If this happens, the Radiator Coolant Hose (Lower) can become brittle and crack, allowing coolant to leak out. If too much coolant leaks out, the engine may not get enough coolant to maintain a safe engine temperature, which could cause your Nissan to overheat. If overheating occurs, it could lead to additional repairs and even damage to the vehicle.
Additionally, the Radiator Coolant Hose (Lower) may bloat, meaning the hose swells. If low coolant causes the engine to overheat, it 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 feel the Radiator Coolant Hose (Lower) on your vehicle needs to be exchanged, it's good to start with a visual inspection. When checking the coolant system, always ensure the vehicle's engine and coolant system are completely cooled down, as the cooling system is under pressure, and heated coolant can spray if something happens to the Radiator Coolant Hose (Lower).
When looking at the Radiator Coolant Hose (Lower), look for swelling, cracks, dry-rot, and warping. Look for coolant leaks on the ground underneath the vehicle, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.
Additionally, look on your dashboard if you think your Radiator Coolant Hose (Lower) is bad. Look for a Low Coolant light 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 the different dashboard lights and their meanings.
