Antifreeze And Engine Coolant: What's The Big Deal?

Key Takeaways:

1. Coolant is a fusion of water and ethylene glycol or propylene glycol. It helps keep your engine from overheating by absorbing heat.
2. The most prevalent type of antifreeze is ethylene glycol, which is poisonous to animals and humans.
3. It is important to check the level of car coolant in your car regularly. The coolant level should be right between the "min" and "max" marks on the radiator.
4. Most cars will have a sticker inside the hood that indicates when to replace the car's coolant.

We know, we know. You're thinking, "Another post about car fluids? Seriously?" But trust us, this is interesting stuff. Especially if you're the kind of person who likes to do your auto maintenance, please bear with us for a few minutes as we take a look at the basics of engine coolant and antifreeze.

Coolant and antifreeze are two of the most important fluids in your car, and it's critical that you understand their function and how to maintain them properly. In this post, Supreme Ford of Slidell will discuss what each fluid does, how to check their levels, and how to add more if necessary. We'll also quickly examine some common myths and misconceptions about these fluids. So, pull up a chair, and let's get started!

How Are Car Coolant & Antifreeze Produced?

Coolant is a fusion of water and ethylene glycol or propylene glycol. It helps keep your engine from overheating by absorbing heat and dissipating it through the radiator. It also prevents corrosion in the engine. The mixture consists of 50% water and 50% antifreeze, which keeps the engine from freezing in winter and boiling in summer.

The most prevalent type of antifreeze is ethylene glycol, which is poisonous to animals and humans. That is why keeping it away from children and pets is crucial. If you must add antifreeze to your car, ensure to do so when the engine is cool.

What Happens If My Car’s Engine Freezes or Overheats

In a nutshell, A frozen engine can cause serious damage. The water in the car coolant can turn to ice, expanding and cracking the engine block, cylinder heads, and radiator. A frozen engine can also cause the coolant hoses to burst and the thermostat to fail.

An overheated engine can also cause serious damage. The pistons can expand, causing the rings to lose their seal and the valves to bend. The cylinder head can warp, and the bearings can fail. An overheated engine can also lead to a blown head gasket, cracked cylinder heads, and warped intake manifolds.

Why is My Coolant Level Low?

Well, there are three possible reasons:

1. A leak in the cooling system
2. Evaporation (coolant evaporates over time)
3. The coolant has not been topped up since the last service

If you think you have a leak, the best thing to do is take your car to a mechanic. A mechanic will be able to find the source and fix it. Getting it fixed as soon as possible is important. A leaking cooling system can cause the engine to overheat, leading to serious engine damage.

If the coolant level has dropped due to evaporation, top up the radiator with coolant until it reaches the "max" mark. Ensure you use the recommended coolant for your car.

Should I Check My Car Coolant's Level Regularly

It is important to check the level of car coolant in your car regularly. The coolant level should be right between the "min" and "max" marks on the radiator. If it's below the "min" mark, add coolant until it reaches the "max" mark. Never drive your car with low coolant levels, as this can damage your engine. Car coolant checks must be a part of your regular car maintenance.

When Is Car Radiator Fluid Replacement Necessary?

Check the condition of your coolant. If it is dirty or contains rust, you must replace it. You should also replace the coolant if it has been in your car for more than two years. To do this:

1. Drain the old coolant from the car's radiator and refill it with a new coolant.
2. Keep in mind that coolant is poisonous, so dispose of it properly.
3. Do not pour it down the drain!

Car antifreeze, however, does not need to be replaced as frequently. You can usually get away with replacing it every four years or so. When you replace it, use the same type of antifreeze in your car. Mixing different types of antifreeze can cause problems.

When Does Your Car Require a Coolant or Antifreeze Service?

Most cars will have a sticker inside the hood that indicates when to replace the car coolant. However, there are other things you can look for to know if it's time for a coolant or car antifreeze service:

1. The engine is overheating frequently
2. There is rust in the radiator
3. The coolant is low
4. There is a leak in the ride's cooling system
5. The coolant is dirty or has debris in it

If you witness these, take your car for a coolant/antifreeze service. Depending on the severity of the problem, you may need a coolant flush. It is when all the old coolant is removed and replaced with new. A radiator service may also be needed, in which case the radiator will be taken apart, cleaned, and repaired as necessary.

IAT and OAT Antifreeze Explained for New Car Owners

IAT coolant is the traditional type of antifreeze and has been used in cars for many years. OAT coolant offers better protection against corrosion and is the antifreeze most commonly used in newer cars.

The main difference between IAT and OAT coolant is the chemicals used to achieve the desired results. IAT coolant uses silicates and phosphates to protect against corrosion, while OAT coolant uses organic acids. While IAT coolant is still used in some cars, OAT coolant is the more common type of antifreeze and is often recommended by automakers.
