What happens when you run out of coolant?
Some folks prefill the hose so that the small amount of air occupying the hose is avoided. Then you open a valve and the hose is now exposed to the vacuum set in the coolant system which basically causes the hose to suck in all the coolant until equilibrium or your run out of coolant so have enough handy.
What causes a car to overheat when idling?
That said, some of the the basic things you can check when your car overheats at idle include: The coolant level. Only check when the engine is cool. Low coolant can cause overheating. Air bubbles in the cooling system can also cause issues. Only use the specified type of antifreeze to top off the system. Fan belt problems
What causes a car’s cooling system to stop working?
A defective fan belt can cause the fan to stop working and not pull cooling air through the radiator. If your on the highway you might not even notice this as the speed of your vehicle will push air through the radiator. Once you stop, that air will not be pushed through your cooling system and you will overheat.
What to do when your car’s coolant level drops?
If you see coolant level drop, add more coolant with the engine running until it’s topped off and staying full. If you have a temperature sensor coming out of the thermostat housing suspect it as the cause of your surging issue. This doesn’t even set a CEL light. You can change it same time as the thermostat replacement.
When to flush the radiator and cooling system?
The fix: When flushing the radiator and cooling system, make sure you run the engine with the pressure cap off for 15 minutes after refilling the system. This will bleed any air from the radiator and cooling system before you replace the pressure cap. Read our comprehensive guide on how to do a coolant flush.

How does the coolant system in a car work?
Car cooling systems rely on a sealed network of hoses to pump coolant/antifreeze around an engine. These hoses are arranged in a sealed loop, which allows a smooth and constant flow of coolant/antifreeze to reach components including the head gasket, cylinder heads and engine block – keeping the engine working at the right temperature.
What happens when a car cooling system fails?
The cooling system is used to maintain operational temperatures which have a number of components that can fail or leak coolant due to the constant heat and vibration of the engine. When internal temperatures go beyond their designed capabilities internal damage can occur such as a cracked cylinder head or engine block.
