Why is my coolant not draining back into the overflow tank?
Now for the answer; When coolant does not return to the radiator from the overflow tank upon cool down there can be only two (2) reasons; 1) Either the hose from the radiator neck to overflow tank is kinked (or too soft and collapses), clogged, broken or does not go far enough into the overflow tank. 2) The radiator cap is defective or loose.
What happens if there is no coolant in the reservoir?
Coolant reservoir plays a major role in ensuring your car runs smoothly. A problem with this component, (like no coolant in the radiator) can cause severe damage to your engine system. Therefore, it is recommendable that you know the work of a coolant reservoir tank and how to figure out issues with your reservoir tank.
What causes coolant to escape from the radiator?
A damaged radiator cap can also break the hoses by building high pressure in them, creating another channel for the escape of coolant. A faulty radiator cap can cause the coolant reservoir to overflow and overheating the vehicle’s engine system.
How long does it take to cool down an overflow tank?
Allow it to cool down. It will take your engine one to two hours to cool down. Once your engine is cool, open your radiator and overflow tank, top your overflow tank till it gets to the full level. And top your radiator till it gets to the brim. Should my coolant overflow be empty?

Why does coolant disappear from the engine reservoir?
Call it antifreeze, a coolant, or even radiator fluid; the purpose is to maintain the engine’s cool. There may be times when the coolant system may fail due to one reason or another. The mystery arises though when magically the coolant disappearing from reservoir is noticed with no potential signs of leakage. Has this happened with your car too?
Is it normal for coolant to evaporate from Radiator?
A coolant leak is bound to happen with issues within the radiator or engine, but there are chances of depleted coolant levels with no trace of leakage. A minute amount of Coolant might evaporate as it’s not a closed system entirely due to the availability of an overflow reservoir.
What are the symptoms of a bad coolant tank?
Below are common symptoms that may appear with a faulty coolant expansion tank. As coolant gets hot due to it absorbing heat from the engine, the liquid expands and creates additional pressure in the radiator.
