- 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 your vehicle's cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to operate how it's supposed to. As the coolant in your Nissan goes through the radiator and coolant system to your engine, it passes through a Radiator Coolant Hose (Lower). It's important your Radiator Coolant Hose (Lower) is free from damage, leaks, cracks, or bloating that could cause damage to your Nissan.
Over time, the rubber in your vehicle's Radiator Coolant Hose (Lower) can wear out. When 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 might not receive enough coolant to keep the engine temperature under control, which could cause your Nissan to overheat. If overheating occurs, it could lead to additional repairs and even damage to the vehicle.
In addition, your Radiator Coolant Hose (Lower) can become bloated, which means the hose swells up. If low coolant causes the engine to overheat, it may cause extremely hot coolant to travel through the Radiator Coolant Hose (Lower), which can make the rubber swell and bloat, potentially causing further cracks and damage to your vehicle's Radiator Coolant Hose (Lower).
If you feel a Radiator Coolant Hose (Lower) on your Nissan needs to be exchanged, a great place to start is 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 heated coolant can spray if the Radiator Coolant Hose (Lower) becomes compromised.
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, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.
Additionally, 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 showing the engine running too hot. Your owner's manual provides an overview of the different dashboard lights and their meanings.
