- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan relies on the cooling system to prevent the engine from overheating. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Upper) to work properly. As your vehicle's coolant fluid 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.
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, allowing coolant to leak out. If too much coolant leaks out, the engine may not get enough coolant to keep the engine temperature under control, potentially causing your Nissan to overheat. If overheating occurs, it could lead to added repairs and further damage to your vehicle.
Additionally, your Radiator Coolant Hose (Upper) can become bloated, meaning the hose bulges out or swells in some places. If low coolant causes the engine to overheat, it can cause superheated coolant to pass through the Radiator Coolant Hose (Upper), which can make the rubber swell and bloat, possibly causing additional cracks and damage to the Radiator Coolant Hose (Upper).
If you believe the Radiator Coolant Hose (Upper) on your vehicle needs to be replaced, a great place to start is a visual inspection. When dealing with the coolant system, always ensure the coolant system and engine are cooled down completely, as the entire cooling system is pressurized, and heated coolant can 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, especially where your Radiator Coolant Hose (Upper) is attached to the vehicle.
Additionally, 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 displaying that your engine is running hot. Your owner's manual provides an overview of your vehicle's dashboard lights and what they mean.
