Your INFINITIs cooling system is designed to ensure your vehicle doesnt overheat. And this cooling system relies on a quality, functioning Radiator Coolant Hose (Upper) to work like it should. As your vehicles coolant fluid goes through the radiator and coolant system to your engine, it travels through a Radiator Coolant Hose (Upper). Its crucial that your Radiator Coolant Hose (Upper) is free from damage, leaks, cracks, or bloating that may cause further damage to your vehicle.

Over time, the rubber that makes up your INFINITIs Radiator Coolant Hose (Upper) can wear out. If this happens, the Radiator Coolant Hose (Upper) may become brittle and crack, causing a coolant leak. If enough coolant leaks out, the engine might not receive enough coolant to maintain a safe engine temperature, potentially causing your INFINITI to overheat. If the engine overheats, it may lead to added repairs and further damage to your vehicle.

Additionally, the Radiator Coolant Hose (Upper) may bloat, meaning the hose bulges out or swells in some places. An overheating engine due to low coolant may cause extremely hot coolant to travel through the Radiator Coolant Hose (Upper), which can make the rubber swell and bloat, possibly causing additional cracks and damage to your vehicles Radiator Coolant Hose (Upper).

If you believe your INFINITIs Radiator Coolant Hose (Upper) needs to be replaced, its good to start with a visual inspection. When dealing with the coolant system, always ensure the coolant system and engine are completely cooled down, as the cooling system is under pressure, and super hot coolant may spray if the Radiator Coolant Hose (Upper) becomes compromised.

When inspecting your Radiator Coolant Hose (Upper), look for cracks, warping, dry-rotted areas, and swelling. Look for coolant leaks on the ground underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Upper) is located on the vehicle.

Also, look on your dashboard if you think your Radiator Coolant Hose (Upper) is bad. Look for a Low Coolant light or if the temperature gauge is showing the engine running too hot. Your owners manual gives an overview of your vehicles dashboard lights and what they mean.
