In this guide, we’ll break down the differences between Glacia 33% and 50% so you can pick the best coolant for your car.

What is Engine Coolant?

Engine coolant is a special liquid that helps keep your car’s engine from overheating or undercooling. When your engine runs, it becomes very hot—hot enough to damage essential parts. Coolant absorbs this heat and carries it to the radiator, where it cools down again. In winter, coolant also stops the engine from freezing or cracking. That’s why coolant is sometimes called antifreeze.

Coolant also protects the engine from rust and corrosion. Most coolants are made by mixing water with chemicals like ethylene glycol or propylene glycol.

Inside your car, there is a coolant reservoir connected to the radiator. When the engine is running, a pump pushes coolant through the engine block to absorb heat. Then it flows to the radiator to cool, and the cycle continues. 

When you first start your car, the coolant doesn’t go through the radiator until the engine warms up. Once the engine reaches a specific temperature, a valve opens, allowing coolant to flow through the radiator to keep everything at the right temperature.

Why Do I Need Engine Coolant?

Your car needs engine coolant to keep the engine at a safe temperature. Coolant circulates through the engine and radiator to keep the engine from overheating. It also stops the engine from freezing in freezing weather. Without coolant, your car cannot run safely or efficiently.

If you don’t change your coolant on time, it can cause expensive damage to parts like the radiator, water pump, and pipes. Old coolant becomes weak, and rust or dirt can build up in the system. This makes it harder for the car to stay cool. 

If you ever see smoke coming from under your hood, it might be because the coolant system is failing. Your dashboard will usually warn you before things get that bad. When your car says it’s time for a coolant flush, it’s best to replace it right away.

It’s also essential to use the correct coolant for your car to keep everything working correctly.

What Makes a Good Engine Coolant?

A good engine coolant is super important because it stops your car’s engine from freezing in winter and overheating in summer. It also protects your engine from rust and helps it run better. But what makes coolant work so well? Let’s break it down.

• Water. Most coolants are about half water. Straight antifreeze doesn’t have water, so you either mix it with water yourself or buy premixed coolant. Both ways work if you follow the instructions.
• Ethylene Glycol. This is the main ingredient in most coolants. It keeps the engine from freezing in freezing weather and from boiling in really hot weather. It’s been used since World War I.
• Propylene Glycol. Some coolants use this instead of ethylene glycol. It’s thicker, so it doesn’t transfer heat quite as fast, but it’s safer if kids or pets are around.
• Corrosion Inhibitors. Coolant needs additives to stop rust and corrosion. Different countries use different types. For example, Asian cars use phosphates and carboxylates, while European cars use silicates and carboxylates. Each type solves a different problem.

Not all additives are better than others—they work differently. Some improve heat transfer, while others prevent scale from forming in the engine. You can even use certain coolant additives without antifreeze to help your engine run cooler.

What is the Best Coolant for My Car?

The best coolant for your car depends on its type, age, and where it was made. Knowing your car’s make, model, and year helps you pick the proper coolant. Using the wrong one can make your car run poorly or even damage the engine. Here are some tips to help you choose the appropriate coolant.

• Check the Color: Coolants come in different colors, which often match specific types of cars. For example, IAT coolant is usually green, and HOAT coolant is frequently turquoise. But color alone isn’t always enough—read the label to make sure it works with your car.
• Go to the Source: Your car’s owner’s manual tells you which coolant is best. Don’t have one? You can usually find this info online. The manual shows OEM-approved formulas, but there are also good aftermarket options.
• Don’t forget the Water: Some coolants are ready to use, while others need to be mixed 50/50 with water. Use soft tap water if needed. Be careful with the ratio—too strong or too weak can hurt performance.

Quick Tip: If your coolant is low and you’re in a pinch, you can add water to get to the nearest shop safely.

Types of Coolant for Your Car

Cars need the proper fluids to stay healthy and run well—just like people! Coolant is one of the most essential fluids, and there are different types.

• IAT (Inorganic Additive Technology): The oldest type of coolant. It uses special chemicals to stop rust and corrosion.
• OAT (Organic Additive Technology): A newer type that uses organic acids to protect your engine from rust.
• HOAT (Hybrid Organic Additive Technology): The newest kind. It mixes both inorganic chemicals and organic acids to keep your engine safe.

Which one is right for your car? Ask a mechanic or do some research. Using the proper coolant helps your car stay healthy for many years!

What Happens When Your Engine Overheats or the Coolant Freezes?

If your engine gets too hot, it can burn oil and damage critical parts, such as the engine block. The metal inside can warp, and in terrible cases, the engine can stop working entirely and need a full replacement.

On the other hand, if it’s really cold and the coolant isn’t mixed right, it can freeze and expand inside the engine. This can crack or damage the engine, causing serious problems.

That’s why using the proper coolant mix is super important. It keeps your engine at the right temperature, avoids costly repairs, and helps your car last longer.
