- Important part of cooling system
- The hose coolant travels through to get between the radiator and engine
- Replace when cracked or leaking
Your Nissan depends on its cooling system to keep the vehicle from overheating. And the cooling system depends on a functioning, quality Radiator Coolant Hose (Lower) to operate properly. As the coolant fluid in your Nissan goes through the radiator and coolant system to your engine, it has to go through a Radiator Coolant Hose (Lower). It's crucial that your Radiator Coolant Hose (Lower) is free from cracks, bloating, or leaks that could cause damage to your Nissan.
Over time, the rubber in the Radiator Coolant Hose (Lower) on your Nissan can get old and wear out. When 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 may not get enough coolant to control the engine's temperature, potentially causing your Nissan to overheat. If the engine overheats, it may lead to repairs and damage your vehicle.
Also, the Radiator Coolant Hose (Lower) 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 (Lower), which can make the rubber swell and bloat, likely causing additional damage and cracks to the Radiator Coolant Hose (Lower).
If you feel a Radiator Coolant Hose (Lower) on your Nissan needs to be exchanged, a great place to start is a visual inspection. When working with the coolant system, always ensure the vehicle's engine and coolant system are completely cooled down, as the cooling system is under pressure, and heated coolant can spray if the Radiator Coolant Hose (Lower) breaks.
When checking out the Radiator Coolant Hose (Lower), look for cracks, warping, dry-rotted areas, and swelling. Check for coolant fluid leaks underneath the vehicle, specifically underneath where the Radiator Coolant Hose (Lower) is located on the vehicle.
Additionally, look at your dashboard if you suspect a bad Radiator Coolant Hose (Lower). Check if the Low Coolant light is illuminated or if the temperature gauge is displaying that your engine is running hot. Your Nissan owner's manual has an overview of dashboard lights and their meanings.
