- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan's cooling system is designed to prevent the engine from overheating. And the cooling system depends on a quality, functioning Radiator Coolant Hose (Lower) to work properly. As the coolant fluid in your Nissan passes through the radiator and coolant system to your engine, it travels through a Radiator Coolant Hose (Lower). It's important your Radiator Coolant Hose (Lower) is free from leaks, cracks, or bloating that could cause more damage to your Nissan.
Eventually, the rubber in your Nissan's Radiator Coolant Hose (Lower) can get old and wear out. When this happens, your Radiator Coolant Hose (Lower) can get brittle and crack, causing a coolant leak. If too much coolant leaks out, the engine might not receive enough coolant to control the engine's temperature, which could cause your Nissan to overheat. If overheating occurs, it could lead to repairs and damage your vehicle.
In addition, your Radiator Coolant Hose (Lower) can become bloated, meaning the hose bulges out or swells in some places. 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 think your Nissan's Radiator Coolant Hose (Lower) needs replacing, a great place to start is a visual inspection. When dealing 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 something happens to the Radiator Coolant Hose (Lower).
When inspecting your Radiator Coolant Hose (Lower), look for dry-rot, cracks, swelling, or warping. Check the ground underneath the vehicle for coolant leaks, specifically underneath where the Radiator Coolant Hose (Lower) is located on the vehicle.
Also, look at your dashboard if you suspect a bad Radiator Coolant Hose (Lower). Look for a Low Coolant light or if the temperature gauge is showing the engine running too hot. Your Nissan owner's manual has an overview of the different dashboard lights and their meanings.
