- 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 ensure your vehicle doesn't overheat. And this cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to operate properly. As your vehicle's coolant fluid passes through the radiator and coolant system to the engine, it passes through a Radiator Coolant Hose (Lower). It's crucial that your Radiator Coolant Hose (Lower) is free from leaks, cracks, or bloating that could cause damage to your Nissan.
Eventually, the rubber that makes the Radiator Coolant Hose (Lower) on your Nissan can get worn out. If this happens, the Radiator Coolant Hose (Lower) may become brittle and crack, allowing coolant to leak out. If too much coolant leaks out, the engine might not receive enough coolant to control the engine's temperature, potentially causing your Nissan to overheat. If overheating occurs, it could lead to additional repairs and even damage to the vehicle.
Also, your Radiator Coolant Hose (Lower) can become bloated, which means the hose swells up. An engine overheating from low coolant could cause intensely heated coolant to pass through the hose, making the rubber in the hose bloat and swell, likely causing additional damage and cracks to your Radiator Coolant Hose (Lower).
If you think your Nissan's Radiator Coolant Hose (Lower) needs to be exchanged, a great place to start is a visual inspection. When dealing with the coolant system, always ensure the coolant system and engine are completely cool, as the entire cooling system is pressurized, and super hot coolant may spray if the Radiator Coolant Hose (Lower) breaks.
When checking out the Radiator Coolant Hose (Lower), look for swelling, cracks, dry-rot, and warping. Check the ground underneath the vehicle for coolant leaks, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.
In addition, 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 displaying that your engine is running hot. Your owner's manual has an overview of the different dashboard lights and their meanings.
