- 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 prevent the engine from overheating. And this cooling system relies on a working, quality Radiator Coolant Hose (Lower) to operate how it's supposed to. As the coolant fluid in your Nissan goes through the radiator and coolant system to your engine, it has to go 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 damage to your Nissan.
In time, the rubber that makes your vehicle's Radiator Coolant Hose (Lower) can get old and 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 may not get enough coolant to keep the engine temperature under control, which could cause your Nissan to overheat. An overheated engine could lead to additional repairs and even damage to the vehicle.
Additionally, the Radiator Coolant Hose (Lower) can get bloated, 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), making the rubber in the hose bloat and swell, potentially causing further cracks and damage to your vehicle's Radiator Coolant Hose (Lower).
If you feel the Radiator Coolant Hose (Lower) on your vehicle needs to be replaced, a visual inspection is often a good place to start. When working with the coolant system, always ensure the coolant system and engine are completely cool, as the cooling system is under pressure, and super hot coolant may spray if the Radiator Coolant Hose (Lower) breaks.
When checking out the Radiator Coolant Hose (Lower), look for dry-rot, cracks, swelling, or warping. Check for coolant fluid leaks underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Lower) is located on 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 showing the engine running too hot. Your owner's manual gives an overview of your vehicle's dashboard lights and what they mean.
