- 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 your vehicle's cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to work correctly. As the coolant in your Nissan passes through the radiator and coolant system to the engine, it passes through a Radiator Coolant Hose (Lower). It's important 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 wear out. When this happens, the Radiator Coolant Hose (Lower) can become brittle and crack, causing a coolant leak. If enough coolant leaks out, the engine might not receive enough coolant to keep the engine temperature under control, which could cause your Nissan to overheat. If the engine overheats, it may lead to added repairs and further damage to your vehicle.
Additionally, your Radiator Coolant Hose (Lower) can become bloated, meaning the hose swells. An overheating engine due to low coolant can cause superheated coolant to pass through the Radiator Coolant Hose (Lower), which can make the rubber swell and bloat, possibly causing additional cracks and damage to your vehicle's Radiator Coolant Hose (Lower).
If you believe your Nissan's Radiator Coolant Hose (Lower) needs replacing, a visual inspection is often a good place to start. When working with the coolant system, always ensure the vehicle's engine and coolant system are completely cool, as the entire cooling system is pressurized, and extremely hot coolant fluid can spray if something happens to the Radiator Coolant Hose (Lower).
When looking at the Radiator Coolant Hose (Lower), look for dry-rot, cracks, swelling, or warping. Look for coolant leaks on the ground underneath the vehicle, 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 to see if the Low Coolant light is on or if the temperature gauge is in the red, meaning your engine is running too hot. Your owner's manual gives an overview of the different dashboard lights and their meanings.
