Your Nissan 370Z depends on its cooling system to prevent the engine from overheating. And your vehicles cooling system relies on a functioning, quality Radiator Coolant Hose (Lower) to work correctly. As the coolant fluid in your Nissan travels through the coolant system and radiator to your engine, it travels through a Radiator Coolant Hose (Lower). Its crucial that your Radiator Coolant Hose (Lower) is free from cracks, bloating, or leaks that could cause damage to your Nissan.
Eventually, the rubber that makes up your Nissans Radiator Coolant Hose (Lower) can get old and wear out. When this occurs, the Radiator Coolant Hose (Lower) may become brittle and crack, causing coolant to leak out. If too much coolant leaks out, your vehicles engine may not receive enough coolant to keep the engine temperature under control, which may cause overheating in your Nissan. If the engine overheats, it may lead to additional repairs and even damage to the vehicle.
Also, your Radiator Coolant Hose (Lower) can become bloated, which means the hose swells up. An engine overheating from low coolant could cause intensely heated coolant to pass through the hose, causing the rubber material to swell and bloat, likely causing additional damage and cracks to the Radiator Coolant Hose (Lower).
If you feel your Nissans Radiator Coolant Hose (Lower) needs to be exchanged, a great place to start is a visual inspection. When dealing with the coolant system, always ensure the vehicles engine and coolant system are cooled down completely, as the cooling system is under pressure, and heated coolant can spray if the Radiator Coolant Hose (Lower) becomes compromised.
When looking at the Radiator Coolant Hose (Lower), look for cracks, warping, dry-rotted areas, and swelling. Check for coolant fluid leaks underneath the vehicle, especially where your Radiator Coolant Hose (Lower) is attached to the vehicle.
Also, 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 in the red, meaning your engine is running too hot. Your Nissan owners manual gives an overview of your vehicles dashboard lights and what they mean.
