Antifreeze is a tinted liquid that you put (along with water) in your radiator to help regulate engine temperature. Its key ingredient is ethylene glycol, which lowers water's freezing point and raises its boiling point. This helps prevent the water in your radiator from freezing, boiling, or evaporating.

Do I need antifreeze in my radiator?
Antifreeze keeps the water in your radiator and engine from freezing in cold temperatures. ... Having a low amount of antifreeze can cause your engine to overheat or freeze up, costing you big bucks in the long run, so make sure to check these levels every 2 to 3 months.
What happens in a car radiator with no antifreeze?
Coolant circulates through your car and extracts heat from various components, keeping their operating temperature within normal parameters. Without coolant, there's nothing to extract this heat, and these parts quickly overheat and break down.
Does the car need to be running when adding antifreeze?
If the engine is cool, or at least not hot, you can remove the radiator cap and add fluid directly to the radiator, even with the engine running. Under normal conditions, the coolant expands when it gets hot and flows into the expansion tank.
Why would antifreeze be low?
If your car's coolant level is dropping, it is almost always due to leaks in the cooling system – the hoses, radiator or radiator cap, for example. Symptoms of this can be a rising temperature gauge, a sweet odour (the smell of antifreeze), problems with your car's heater or increased fuel consumption.
How long can you drive without coolant?
However, if you absolutely must start your car without coolant, it can probably run for about a minute without too much risk of damage. You may be able to get away with as much as 5 minutes of running without coolant, depending on the engine, car model, and how hard you're asking the engine to work.
Is coolant the same as antifreeze?
Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.
How often should antifreeze be changed?
However, most manufacturers recommend flushing the cooling system and changing the coolant as often as every 30,000 miles regardless to avoid serious problems such as engine failure.
Can you pour antifreeze directly into the radiator?
On all vehicles that have a reservoir you add it to the reservoir, unless it is totally empty, then you can add it to the radiator directly. Once the radiator is full you will want to finish topping it off through the reservoir. If you just need to add because it is loww, then always use the reservoir.
What happens if you put too much antifreeze in your car?
Coolant expands as it heats and contracts when it cools. The extra space prevents damage to your engine and hoses. ... In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
What causes loss of antifreeze 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. ... Any trace of exhaust gases in the coolant.
Can I use water instead of coolant in an emergency?
Water by itself can't do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle's engine. Plus, it doesn't absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
Is it OK to put water instead of coolant?
Yes, you could use water as a coolant in an emergency. However, doing so is not recommended since water won't work well beyond its freezing and boiling points. This could also cause expensive engine damage.
What color should antifreeze be?
Fresh antifreeze is a clear brightly coloured liquid, usually blue, red, green, violet, yellow or orange but this will vary depending on the manufacturer's formulation. Over time, your coolant will become dirty losing its colour and becoming darker, often an oxidized shade of brown.
Does antifreeze prevent rust?
It provides protection from rust and corrosion and does not harm rubber hoses and plastics. Antifreeze should not corrode metal parts, attack rubber, become viscous at low temperatures, or evaporate readily at the ordinary engine operating temperature.
