Hose Bottom.
Flexible hose that is part of the engine cooling system.

• 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 keep the vehicle from overheating. And this cooling system relies on a functioning, quality Radiator Coolant Hose (Lower) to operate how it's supposed to. As your vehicle's coolant fluid goes through the radiator and coolant system to your engine, it passes through a Radiator Coolant Hose (Lower). It's important your Radiator Coolant Hose (Lower) is free from cracks, bloating, or leaks that could cause damage to your INFINITI.

Eventually, the rubber in your vehicle's Radiator Coolant Hose (Lower) can get worn out. If this happens, the Radiator Coolant Hose (Lower) may become brittle and crack, causing a coolant leak. If an excess amount of coolant leaks out, the engine might not receive enough coolant to maintain a safe engine temperature, potentially causing your INFINITI to overheat. If overheating occurs, it could lead to repairs and damage your vehicle.

Also, your Radiator Coolant Hose (Lower) can become bloated, meaning the hose swells. An engine overheating from low coolant 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 Radiator Coolant Hose (Lower).

If you feel a Radiator Coolant Hose (Lower) on your INFINITI needs to be exchanged, a great place to start is a visual inspection. When working with the coolant system, always make sure the engine and coolant system are completely cool, as the cooling system is pressurized, and super hot coolant may spray if the Radiator Coolant Hose (Lower) breaks.

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

In addition, check the dashboard if you feel you have a bad Radiator Coolant Hose (Lower). 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 your vehicle's dashboard lights and what they mean.
