• Important part of cooling system
• The hose coolant travels through to get between the radiator and engine
• Replace when cracked or leaking

Your INFINITI relies on the cooling system to ensure your vehicle doesn't overheat. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Upper) to work like it should. As the coolant in your INFINITI goes through the radiator and coolant system to your engine, it travels through a Radiator Coolant Hose (Upper). It's crucial that your Radiator Coolant Hose (Upper) is free from leaks, cracks, or bloating that may cause further damage to your vehicle.

Eventually, the rubber that makes up your vehicle's Radiator Coolant Hose (Upper) can get worn out. If this happens, the Radiator Coolant Hose (Upper) may become brittle and crack, causing coolant to leak out. If too much coolant leaks out, the engine might not receive enough coolant to keep the engine temperature under control, potentially causing your INFINITI to overheat. If the engine overheats, it may lead to added repairs and further damage to your vehicle.

In addition, the Radiator Coolant Hose (Upper) may bloat, meaning the hose swells. If low coolant causes the engine to overheat, it can cause superheated coolant to pass through the Radiator Coolant Hose (Upper), causing the rubber material to swell and bloat, possibly causing additional cracks and damage to the Radiator Coolant Hose (Upper).

If you think your INFINITI's Radiator Coolant Hose (Upper) needs to be replaced, it's good to start with a visual inspection. 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 heated coolant can spray if something happens to the Radiator Coolant Hose (Upper).

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, especially where your Radiator Coolant Hose (Upper) is attached to the vehicle.

Also, check the dashboard if you feel you have a bad Radiator Coolant Hose (Upper). Look for a Low Coolant light or if the temperature gauge is displaying that your engine is running hot. Your owner's manual gives an overview of the different dashboard lights and their meanings.
