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.
Can I use antifreeze instead of coolant?
Well, antifreeze and engine coolant are similar, but not the same. Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Does my car need coolant or antifreeze?
Along with fuel and oil, antifreeze is essential to a properly functioning engine. Without it, the heat from combustion would cause the engine to rapidly overheat, or even completely seize up.
Why is coolant called antifreeze?
In fact, the radiator cools the engine coolant after it runs through the engine. We also get asked, is coolant the same as antifreeze? The answer to this question is yes and no. Manufacturers of antifreeze create a solution called ethylene-glycol, which has anti-freezing properties.
Are radiator coolant and antifreeze the same thing?
And now you know that antifreeze and coolant are basically the same thing and can be generically referred to as radiator fluid. And you also know this fluid is key to keeping your vehicle engine in good working order and helps prevent it from freezing or overheating in any weather.

What happens if I put antifreeze in coolant?
Filling a Cooling System With Pure Antifreeze Can Also Damage the Engine. Not only does pure antifreeze have a higher freezing temperature than coolant, but a couple of issues will also arise if you use only it in your cooling system: The engine gets more prone to overheating.
Is it OK to use water as coolant?
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.
How far can I 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.
What happens if the coolant is low?
When coolant is low, your engine will start to heat up. The feature will automatically shut off the engine to prevent damaging the engine. Once your engine cools down, you will be able to drive your car again.
Does coolant affect AC?
Yes, coolant can affect a car's air conditioning by impacting the car's temperature, humidity, and airflow.
Can I add coolant straight to the radiator?
If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When the coolant rises to the cold fill line, replace the cap and tighten it until you feel it click.
Does it matter what kind of coolant I use?
Well, you use the coolant that is specified in your owner's manual. If you just need to top it up, the recommendation is still the same, however it is unlikely to cause any serious problems if you add a litre of a different type of coolant, as long as you follow the manufacturer's maintenance schedule.
How much antifreeze Do I need to fill my radiator?
Answer provided by. Typically, a car can hold up to three gallons of coolant. If you need to top off your car's engine coolant, just follow these steps: Park your car on a flat surface and let it sit for an hour or two, or until the engine is cool.

How often should I top up my coolant?
Antifreeze should be replaced every 3-5 years depending on how often and how far you drive your car, its age, and the temperature of where you usually drive. Extra care needs to be taken in the summer months, especially if it's a hot day, so make sure you check your coolant levels before the start of the summer.
How long does coolant last in a car?
HOW OFTEN SHOULD YOU FLUSH THE COOLANT? 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.
How do I check my antifreeze in my car?
When the engine reaches operating temperature, insert the positive probe directly into the coolant. Rev the engine to 2,000 rpm and place the negative probe on the negative battery terminal. If the digital meter reads . 4 volts or less, your coolant is in good condition.
Can I top up coolant with tap water?
No, you should use distilled water or better yet, de-ionized water. The reason for this is that tap water has minerals that can deform deposits inside the radiator and the cooling system passages of your engine.
What happens if I add water to 50/50 coolant?
While you can drive the car for a short time using water in place of the coolant, it won't effectively protect your engine. This means its essential to get the problem that caused a low coolant level fixed as soon as possible, and the radiator filled with a 50/50 ratio of coolant to water.
Will a car overheat with just water?
If you were to just use water rather than the coolant mixture, high temperatures inside the motor would easily boil that water and cause it to evaporate, meaning you'd quickly have no coolant at all and the engine would easily overheat.
How long after adding coolant can I drive?
How long do I run the engine after adding coolant? “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”
Why is my coolant low but no leaks?
If you've ruled out an internal leak, that means your engine is burning the coolant somewhere else. The most common place is the radiator cap. Radiator caps hold the pressure inside the system, but if it's not sealing properly, then some hyper pressurized coolant will escape in the form of steam.
What is antifreeze made of?
Antifreeze is a concentrated, glycol-based liquid that must be diluted with water before use – at which point it is referred to as coolant. Alternatively, you can purchase pre-mixed engine coolant, a ready-to-use solution of antifreeze and water.
Can you use antifreeze and coolant interchangeably?
It implies that antifreeze and coolant can be used interchangeably, but they are not the same liquid. Yes, you can use them interchangeably because both help to prevent freezing due to cold temperature and boiling due to extremely high temperature.
What does anti-freeze do in car coolant?
As we already clarified, the anti-freezes a part of the coolant that prevents water from freezing quickly. In other words, anti-freeze helps water drop its freezing point below the specific numbers, so coolant helps serve your vehicle in very cold environments.
What is the difference between 50-50 coolant and antifreeze?
The 50-50 mixture provides enough cooling for engines that run at more than 200 degrees, while the antifreeze properties prevent freezing for cold temperatures below 30 degrees. However, in cases of extremely cold temperatures, the mixture can be as high as 70% antifreeze.
