Your INFINITI relies on the cooling system to prevent the engine from overheating. And this cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to operate how its supposed to. As the coolant fluid in your INFINITI goes through the radiator and coolant system to your vehicles engine, it has to go through a Radiator Coolant Hose (Lower). Its crucial that your Radiator Coolant Hose (Lower) is free from leaks, cracks, or bloating that could cause damage to your INFINITI.

Eventually, the rubber in your INFINITIs Radiator Coolant Hose (Lower) can get worn out. When this happens, your Radiator Coolant Hose (Lower) can get brittle and crack, allowing coolant to leak out. If too much coolant leaks out, the engine may not get enough coolant to maintain a safe engine temperature, which could cause your INFINITI to overheat. If the engine overheats, it may lead to repairs and damage your vehicle.

Also, your Radiator Coolant Hose (Lower) can become bloated, which means the hose swells up. If low coolant causes the engine to overheat, it may cause extremely hot coolant to travel through the Radiator Coolant Hose (Lower), which can make the rubber swell and bloat, potentially causing further cracks and damage to your vehicles Radiator Coolant Hose (Lower).

If you feel a Radiator Coolant Hose (Lower) on your INFINITI needs to be replaced, a visual inspection is often a good place to start. When working with the coolant system, always ensure the vehicles engine and coolant system are completely cool, as the cooling system is pressurized, and heated coolant can spray if something happens to the Radiator Coolant Hose (Lower).

When checking out the Radiator Coolant Hose (Lower), look for cracks, warping, dry-rotted areas, and swelling. Look for coolant leaks on the ground underneath the vehicle, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.

In addition, look at your dashboard if you suspect a bad Radiator Coolant Hose (Lower). Check to see if the Low Coolant light is on or if the temperature gauge is displaying that your engine is running hot. Your INFINITI owners manual has an overview of your vehicles dashboard lights and what they mean.
