Understanding the difference between antifreeze and coolant is important for keeping your engine or automotive business in good working order. These two liquids play different roles in the cooling system, but work hand-in-hand to regulate temperature.
In this post, we will see what antifreeze and coolant are and the differences between them in clear, everyday terms.
What is Antifreeze?
Antifreeze – in a very simple term is a concentrated fluid. It means this is typically made from ethylene glycol or propylene glycol. In its undiluted form, antifreeze itself has a high freezing point and a low boiling point. The main ingredients are glycol plus corrosion inhibitors. The chief motif here is to prevent rust and scale inside the cooling system.
Antifreeze has two primary jobs – the first, as its name implies – it prevents freezing in cold temperatures. But it also raises the boiling point of the coolant solution. As a result, the liquid doesn’t boil away inside a hot engine. One thing to note- antifreeze contains glycol and other additives but lacks the water content needed for effective heat transfer.
What is Coolant?
Coolant in simple words – a mixture of antifreeze and water, usually at a 50/50 ratio. When antifreeze is blended with water, you get a solution with a much lower freezing point and a higher boiling point. The water provides superior heat transfer capabilities. And, the antifreeze gives freezing and boiling protection.
Coolant flows through the radiator, engine block, and hoses to keep the system at optimum temperature. It prevents overheating while also avoiding freezing. The water could not perform these functions alone without the antifreeze component. Coolant also keeps the corrosion inhibitors evenly distributed throughout the system.
Why You Should Never Use Straight Antifreeze
If you pour undiluted antifreeze into your cooling system it can cause significant problems. If not mixed at the proper ratio, antifreeze loses cooling effectiveness and corrosion protection. This is why it is a good idea to use dilute antifreeze with distilled water to create the correct coolant blend before adding it to vehicles.
Just like oil, coolant breaks down over time and should be flushed and replaced. If you see signs like leaks, overheating issues, or odd smells – it indicates the need for cooling system service. Remember, the main thing here is to maintain the proper antifreeze/water balance for engines for longevity and performance. Don’t forget this important maintenance for keeping vehicles running smoothly year after year!
The Key Role of Mono Ethylene Glycol(MEG)
One more important piece of the antifreeze/coolant puzzle is Mono Ethylene Glycol, more commonly known as MEG. This organic compound is a key ingredient in many antifreeze and coolant formulations.
MEG offers some major advantages/Mono Ethylene Glycol Uses:
It has excellent properties as an antifreeze agent to lower the freezing point of water-based coolants.
And, MEG is hygroscopic, meaning it attracts and absorbs moisture. This makes it great for dehydrating natural gas pipelines. It also removes water from industrial systems.
The compound is a versatile chemical intermediary. And, this is why it is used in the production of various everyday plastics and polymers.
MEG is non-toxic to humans and completely biodegradable. This makes MEG a relatively environmentally friendly chemical.
In addition to automotive applications, MEG is also widely used as an aircraft deicer fluid because of its low freezing point and high boiling point. The antifreeze you depend on to keep the automotive engines running during winter months contains this important multipurpose compound.
When you understand the workings of antifreeze, coolant, and MEG, you get an insight into this vital liquid that powers cooling systems of vehicles all year long.
