Types of Antifreeze/Coolant
There are 3 types of anti-freeze/coolant for cars. Each type is formulated differently and offers slightly different advantages compared to others. In any case, a car or any vehicle can actually run on any coolant type.
However, you still need to consider a few factors before buying any car antifreeze. First and foremost, it is important to learn the main difference between each type.
Organic Acid Technology – These coolants come in various dyed colors, mostly orange and dark green. OAT does not contain phosphates or silicates for car protection. It is formulated with organic acids that inhibit corrosion and lengthen the life of the coolant.
Inorganic Acid Technology – This contains phosphate and silicates as corrosion inhibitors that protect the metal cart parts the coolant travels through, like the radiator and the engine. IAT coolant naturally has a clear form, but manufacturers dye it green for ease of identification.
Hybrid-Organic Acid Technology – An HOAT coolant has added silicates that help prevent corrosion and improve aluminum protection. It also comes in different colors like orange and yellow, and should be flushed out of the car system every 5 years.
Car manufacturers typically use one specific type of antifreeze/coolant for all their lines to make it easier for car owners to choose the correct coolant. You can find a coolant based on color and vehicle manufacturer.
How does Antifreeze Work?
All vehicles produce energy by means of combustion in the engine. This is necessary to make a vehicle run, but it can also result to overheating and damage to the engine.
To avoid such trouble, car manufacturers utilize a cooling system within the engine and radiator of a car. This system uses a coolant fluid, which is a mixture of water and antifreeze, to keep the metal parts cool.
You may have encountered the terms “coolant” and “antifreeze” being used interchangeably. This is somehow correct. The antifreeze or coolant maintains proper levels of temperature in your car, preventing the water from freezing in extreme cold weathers, and from overheating in hotter weather.
A coolant is typically a mix of 50% water and 50% antifreeze. At first, it is poured into the coolant reservoir and the car’s radiator. Later on, you may add more antifreeze between mechanic visits to maintain proper functioning of the engine and of the car as a whole.
Some antifreeze products also contain additional ingredients to protect the metal car parts from rust and corrosion. However, these ingredients tend to break down over time, and the antifreeze becomes hazardous to the engine.
When the antifreeze is already at the end of its service life, flush the entire system clean and replace it with new, fresh coolant. You may take your vehicle to a garage or a professional mechanic for proper replacement.
How to Add Coolant to Your Vehicle
Adding antifreeze/coolant to your vehicle to maintain cleanliness in the coolant system is helpful to keep your car running smoothly in any road or weather condition.
This process is simple and all you need are: work gloves, a funnel, safety glasses, a flashlight, and the coolant. Do not add coolant to your car right after driving. Allow your car to cool down for at least 3 hours.
To begin, lift your car’s hood and locate the reservoir for the coolant. The reservoir is typically a clear container with a screw-top located near the radiator. It is often made of plastic material.
Unscrew the cap on the coolant reservoir and see how much antifreeze or coolant is left in there. You may need to use a flashlight to check it.
Pour in the coolant to the reservoir and fill it up to the maximum capacity line. Once full, screw the plastic cap back on and start your car so the coolant runs through the engine and radiator.
For more specific instructions, you may refer to your car’s owner’s manual. It may have special precautions and a diagram or illustration to help you locate the coolant reservoir.
How to Maintain your Antifreeze/Coolant
Keeping your car’s coolant system appropriately filled with a coolant/antifreeze formula is crucial in maintaining a well-running vehicle. It prevents conditions causing a serious injury or breakdown to your car’s engine.
It is highly recommended to have your coolant system flushed clean and refilled every 5 years, or about every 150,000 miles. It is also better to do the process of adding coolant to your car in a garage, instead of doing it on your own.
It can be too messy and the coolant is toxic, thus can be harmful to human health. The fluid has to be labeled, captured carefully, and brought to a facility for hazardous waste.
Any extra water or other fluid that you use in flushing the system should also be captured and labeled. The mechanics or car technicians have the procedure and system to properly do this.
Again, coolants are extremely toxic. Never let it run out into the street or driveway, or drain it onto the ground. It tastes sweet and may attract your pets and other animals. If they drink it, they will die.
It may also grab the attention of curious children and come into contact to them. If you did the process in your home garage and aren’t sure how to dispose the coolant, contact a mechanic and ask for help.
