- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan depends on its cooling system to ensure your vehicle doesn't overheat. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Lower) to work properly. As the coolant fluid in your Nissan passes through the radiator and coolant system to you vehicle's engine, it passes through a Radiator Coolant Hose (Lower). It's essential that the Radiator Coolant Hose (Lower) remain free from cracks, bloating, or leaks 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 occurs, the Radiator Coolant Hose (Lower) may become brittle and crack, causing a coolant leak. If too much coolant leaks out, the engine may not get enough coolant to control the engine's temperature, which may cause overheating in your Nissan. An overheated engine could lead to repairs and damage your vehicle.
In addition, the Radiator Coolant Hose (Lower) may bloat, meaning the hose bulges out or swells in some places. If low coolant causes the engine to overheat, it could cause intensely heated coolant to pass through the hose, causing the rubber material to swell and bloat, potentially causing further cracks and damage to your vehicle's Radiator Coolant Hose (Lower).
If you believe a Radiator Coolant Hose (Lower) on your Nissan needs to be replaced, a great place to start is a visual inspection. When working with the coolant system, always make sure the engine and coolant system are completely cool, 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 swelling, cracks, dry-rot, and warping. Check the ground underneath the vehicle for coolant leaks, specifically where the Radiator Coolant Hose (Lower) attaches to the vehicle.
In addition, look on your dashboard if you think your Radiator Coolant Hose (Lower) is bad. Check if the Low Coolant light is illuminated or if the temperature gauge is showing the engine running too hot. Your Nissan owner's manual gives an overview of dashboard lights and their meanings.
