What happens if radiator has no water?
Driving without coolant, or with low coolant levels, can cause internal temperatures to rise to dangerously high levels which can damage a number of engine parts including the water pump, head gasket, cylinder and piston timing, and connector rods.
Why is the water not circulating in my car?
The coolant level could be extremely low because of long-term neglect, or because a coolant leak has developed in the radiator or radiator hoses. The thermostat that allows coolant to circulate may be stuck in the closed position or a clog may have developed, perhaps from debris in the cooling system.
Should I pour water on overheated engine?
Do not pour cold water into a still-hot radiator — it could cause the engine block to crack due to the sudden change in temperature. Note that most cars require a 50/50 mix of coolant with water to prevent overheating, so you won’t be able to drive indefinitely with nothing but water.

Why is my Toyota Prius overheating on the highway?
It may never overheat at lower speeds because it is not working as hard as it does at higher speeds. A closed thermostat will not allow enough coolant to reach the engine to cool it. If you’re only overheating on the highway, you might just replace the thermostat (especially if you’re driving an older vehicle).
