Key Takeaways:
· Antifreeze is formulated using ethylene glycol or propylene glycol.
· Engine coolant can be a mixture of water with glycols or just water.
· Antifreeze is usually green, red, or yellow, whereas an engine coolant can be colorless or of a similar color as the antifreeze added to it.
· Engine coolant can be used in all engines, including those made from aluminum, brass, copper, and iron.
· If you're unsure when to use antifreeze/coolant for your car's radiator, consult the car owner's manual for your specific vehicle.
Suppose you're looking to purchase a new or pre-owned vehicle. In that case, the discussion between antifreeze vs. engine coolant might have piqued your interest. Knowing the difference between antifreeze and engine coolant is essential as both liquids are used to keep your car's engine from overheating or freezing. However, they have different chemical compositions and benefits.
Antifreeze is formulated using ethylene glycol or propylene glycol. In contrast, engine coolant can be a mixture of water, antifreeze, or plain distilled water.
Antifreeze is essential for preventing the engine from freezing in cold weather. At the same time, the engine coolant keeps the temperature within the desired limits.
Antifreeze & Engine Coolant: The Key Differences
Color Options
Antifreeze is usually green, red, or yellow. At the same time, engine coolant can be colorless or of the same color as the antifreeze, it is mixed with.
Chemical Composition
Antifreeze contains ethylene glycol or propylene glycol as the main ingredient. On the other hand, engine coolant is a mixture of water and glycol.
Additives
Antifreeze has additives to protect the engine from corrosion.
Suitability Based on Engine Type
Antifreeze is suitable for use in aluminum and cast-iron engines. On the other hand, engine coolant can be used in all car engines, including those made from aluminum, brass, copper, and iron.
Suitability Based on Weather Conditions
Antifreeze should be used in cold weather to prevent the engine from freezing. On the contrary, engine coolant can be used in hot and cold weather.
Antifreeze & Engine Coolant: The Benefits
Antifreeze:
· Protects against freezing in cold weather.
· Extends the life of the engine by preventing corrosion.
· It is available in different colors so you can easily see when it needs a replacement.
· It is suitable for use in aluminum and cast-iron engines.
Engine Coolant:
· Protects against overheating and corrosion.
· It can be used in all types of engines, including those made from aluminum, brass, copper, and iron.
· It's available in different colors, so you can easily see when it needs to be replaced.
Antifreeze/Coolant for Pre-Owned Vehicles
There are benefits to using both antifreeze and engine coolant in pre-owned vehicles.
The antifreeze will protect against freezing in cold weather and extend the engine's life by preventing corrosion. Engine coolant will protect against overheating.
However, it's essential to check the levels of both fluids regularly and top them off as needed. If someone neglects to add either liquid to their engine, it could lead to severe damage.
What Happens If You Neglect to Check Your Coolant/Antifreeze Levels?
If you neglect to check your coolant/antifreeze levels, it could lead to your engine freezing or overheating. It's crucial to keep an eye on these levels as lower levels can cause significant damage to your engine and require expensive repairs.
Types of Antifreeze
· Green and orange-colored antifreeze are usually used in older vehicles. It's compatible with all types of metal, including aluminum.
· Yellow-colored Antifreeze is used in European cars. It's not compatible with aluminum and should only be used in engines that have copper radiators.
· Pink-colored Antifreeze can be used in Asian cars. It's not compatible with aluminum and should only be used for engines with copper radiators.
Are you looking to purchase certified pre-owned vehicles? Here's what you need to know.
Things To Consider Before Purchasing Anti-Freeze Or Engine Coolant
Type Of Climate
The first thing you need to think about is the climate. If you live in an area with a lot of snow and ice, you will want to use antifreeze + water in your car's radiator. Antifreeze has a lower freezing point than water, so it won't freeze in your engine and cause damage.
Type Of Metal
The second thing you need to consider is the type of metal your car's radiator. If your vehicle has a copper radiator, you can use a coolant + antifreeze. However, suppose your car has an aluminum radiator. In that case, you must be careful about what kind of coolant you use. Some coolants are not compatible with aluminum and can cause damage.
Level Of Protection Needed.
The third thing you need to consider is the level of protection you need. Antifreeze contains corrosion inhibitors that protect your engine from rust and corrosion. Engine coolant does not have these inhibitors, which is why it must be used together with an antifreeze.
The Color
The fourth thing you need to consider is the color of the coolant. Antifreeze is typically green, while engine coolant can be any color. The color of the coolant shouldn't matter, but some people prefer to use the same color antifreeze in their car as their engine coolant so they can quickly tell if there's a leak.
The Levels
The final thing you must consider is when to check the levels of antifreeze and engine coolant. Antifreeze should be checked a few times a year, and engine coolant should also be checked several times a year. If you neglect to add antifreeze or coolant to your car, it can cause your engine to freeze or overheat.
What's Best for Your Car's Radiator?
Both engine coolant and antifreeze should be used to protect your car's radiator. For instance, you can use a 50/50 mixture of antifreeze and water. It depends on your climate and driving habits. If you're still unsure about how to effectively use engine coolant, consult the car owner's manual for your specific vehicle.
