Your INFINITI depends on its cooling system to prevent the engine from overheating. And this cooling system relies on a quality, functioning Radiator Coolant Hose (Lower) to operate properly. As the coolant in your INFINITI passes through the radiator and coolant system to your engine, it travels 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 INFINITI.

Over 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, causing coolant to leak out. If an excess amount of coolant leaks out, the engine may not get enough coolant to keep the engine temperature under control, potentially causing your INFINITI to overheat. If the engine overheats, it may lead to additional repairs and even damage to the vehicle.

Additionally, the Radiator Coolant Hose (Lower) may bloat, 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, possibly causing additional cracks and damage to your vehicle's Radiator Coolant Hose (Lower).

If you think your INFINITI's Radiator Coolant Hose (Lower) needs to be exchanged, a visual inspection is often a good place to start. When checking the coolant system, always make sure the engine and coolant system are completely cool, as the entire cooling system is pressurized, and heated coolant can spray if the Radiator Coolant Hose (Lower) becomes compromised.

When checking out the Radiator Coolant Hose (Lower), look for swelling, cracks, dry-rot, and warping. Check for coolant fluid leaks underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Lower) is located on the vehicle.

Additionally, 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 in the red, meaning your engine is running too hot. Your owner's manual has an overview of your vehicle's dashboard lights and what they mean.
