- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan's cooling system is designed to keep the vehicle from overheating. And your vehicle's cooling system relies on a quality, functioning Radiator Coolant Hose (Upper) to operate how it's supposed to. As the coolant in your Nissan passes through the radiator and coolant system to the engine, it has to go through a Radiator Coolant Hose (Upper). It's essential that the Radiator Coolant Hose (Upper) remain free from damage, leaks, cracks, or bloating that could cause more damage to your Nissan.
Over time, the rubber in the Radiator Coolant Hose (Upper) on your Nissan can get worn out. If this happens, the Radiator Coolant Hose (Upper) may become brittle and crack, causing coolant to leak out. If an excess amount of coolant leaks out, your vehicle's engine may not receive enough coolant to maintain a safe engine temperature, potentially causing your Nissan to overheat. If the engine overheats, it may lead to additional repairs and even damage to the vehicle.
In addition, the Radiator Coolant Hose (Upper) 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 (Upper), causing the rubber material to swell and bloat, possibly causing additional cracks and damage to your vehicle's Radiator Coolant Hose (Upper).
If you think a Radiator Coolant Hose (Upper) on your Nissan needs to be replaced, it's good to start with a visual inspection. When working with the coolant system, always make sure the engine and coolant system are completely cooled down, as the cooling system is under pressure, and super hot coolant may spray if the Radiator Coolant Hose (Upper) breaks.
When inspecting your Radiator Coolant Hose (Upper), look for cracks, warping, dry-rotted areas, and swelling. Check the ground underneath the vehicle for coolant leaks, especially where your Radiator Coolant Hose (Upper) is attached to the vehicle.
Additionally, check the dashboard if you feel you have a bad Radiator Coolant Hose (Upper). 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 Nissan owner's manual gives an overview of dashboard lights and their meanings.
