Your Nissan relies on the cooling system to ensure your vehicle doesnt overheat. And your vehicles cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to work properly. As the coolant in your Nissan travels through the coolant system and radiator to your engine, it has to go through a Radiator Coolant Hose (Lower). Its 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 in your vehicles Radiator Coolant Hose (Lower) can get worn out. When this occurs, your Radiator Coolant Hose (Lower) can get brittle and crack, causing coolant to leak out. If too much coolant leaks out, the engine might not receive enough coolant to control the engines 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 bulges out or swells in some places. An engine overheating from low coolant may cause extremely hot coolant to travel through the Radiator Coolant Hose (Lower), which can make the rubber swell and bloat, likely causing additional damage and cracks to your vehicles Radiator Coolant Hose (Lower).

If you feel a Radiator Coolant Hose on your Nissan needs replacing, its good to start with a visual inspection. When dealing with the coolant system, always ensure the vehicles engine and coolant system are cooled down completely, as the cooling system is pressurized, and super hot coolant may spray if the Radiator Coolant Hose (Lower) becomes compromised.

When inspecting your Radiator Coolant Hose (Lower), look for cracks, warping, dry-rotted areas, and swelling. 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. Look for a Low Coolant light or if the temperature gauge is displaying that your engine is running hot. Your Nissan owners manual provides an overview of your vehicles dashboard lights and what they mean.
