could overheat or seize up
. Continued use of an overheated engine could lead to permanent damage, such as pistons welding to the cylinders.

Most engines are designed to run with coolant temperatures
between 160 degrees and 200 degrees
. If temperatures in your engine stay too cool combustion will have to be too rich to keep things running smoothly.
How long does antifreeze last in a vehicle?
Depending on the vehicle and the coolant, the average time between flushes is
two years or 30,000 miles for silicated coolants
and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
What are signs of low coolant?
Warning signs of low or no coolant/antifreeze:
Rising temperature gauge
: A rising temperature gauge may be due to an increase in your engine's temperature. Automatic engine cut-off: Most modern cars are equipped with an automatic engine cut-off feature. When coolant is low, your engine will start to heat up.
Will my car freeze without antifreeze?
With no antifreeze or water,
there is nothing to freeze
so it will be fine to leave it drained of all coolant overnight. If you had antifreeze in there before you started your repair, your motor will be fine. The antifreeze ISN'T so the ENGINE doesn't freeze, it's just “winter-grade” coolant.

Why is my coolant low but no leaks?
When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a
blown head gasket
, a fractured cylinder head, Damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock.

prevent overheating
.
Will a car overheat with just water?
Running
just water in your car's radiator will guarantee overheating and damage
, including to your cylinder heads and engine block. And most tap water contains minerals that will leave deposits inside the radiator, causing corrosion, shortening its life and further diminishing its ability to cool.
Does my car need antifreeze in the winter?
Does my Car Need Coolant In Winter? Your Car's Cooling System (Water Pump, Hoses, Radiator, Thermostat, Heater Core) needs service year-round, regardless of the weather. In winter, the Coolant/Antifreeze
lowers the freezing point and prevents freeze up
, which could Crack an Engine Block.
Is it OK to put straight antifreeze in your car?

you should not run your vehicle on pure antifreeze
.
Do cars burn off coolant?
