How to Select the Best Coolant for Your Car
Buying the right coolant for your car is not an easy task as different types of coolants perform differently. As coolant is going to protect your car engine from frequent changes in climate and corrosion, you need to be extra careful while buying coolant for your car. Therefore, you need to consider several points while choosing the right coolant for your car as you do while choosing other car parts.
→ 1. Choose the right color
Car coolants come in different colors to suit different engines. While choosing the best coolant for your car, you need to ensure that you are choosing the right color of coolant as per the type of your engine. For example, neon green coolant is used in older cars to prevent corrosion on steel parts. Also, after choosing the right color of coolant, you shouldn’t mix that with other colors of coolants. If you mix different colors of coolants, then the coolant may not perform well and lead to failure of the engine.
→ 2. Check the compatibility with your vehicle
While choosing a coolant for your car, you should also check whether that coolant is compatible with your car or not. If you use the wrong coolant in your car engine, then that may damage your engine. Also, you may need to spend more money to repair the car engine if it gets damaged because of the inaccurate coolant. Therefore, you should always check the coolant and ensure that it is compatible with your car before purchasing that.
→ 3. Choose the perfect ratio of coolant
Usually, a ratio of 50% antifreeze and 50% water is considered as the perfect coolant for car engines. This ratio can decrease the temperature of the engine and maintain the coolness inside that. Some coolants come in 50/50 mixture to allow you to use that in your car engine directly. But if you prepare the blend on your own, then you should ensure to maintain the ratio of 50/50 for optimal engine performance. If you make any changes in the ratio, then that coolant may not cool your engine accurately. Therefore, while choosing the best coolant for your car, you should ensure to follow the 50/50 ratio for enhancing your engine performance.
→ 4. Consider the brand
If you buy a coolant from an unrecognized brand, then there might be an issue with the quality of that product. Also, you may not rely on that coolant if you are not familiar with that brand. An unrecognized brand can also offer you a coolant that doesn’t have the perfect ratio. Therefore, you should choose a famous brand on which you can rely. By choosing a good brand, you can ensure that the coolant meets all the standards and won’t harm your car engine. The coolants reviewed in this article are from reliable brands and meets American standards.
→ 5. Choose the right type
There are mainly four types of coolants, OAT, IAT, HOAT, and non-toxic. While buying the best coolant for your car, you should ensure to choose the type of coolant that the manufacturer recommends.
Organic Acid Technology or OAT coolant is an eco-friendly product and free of phosphate and silicate. This coolant is used in trucks, SUVs, etc., and it offers resistance to corrosion. OAT coolant can last for up to five years or 150,000 miles.
Inorganic Acid Technology or IAT coolant includes silicates and phosphates and is an ethylene glycol-based formulation. Because of this, the IAT coolants are not frequently used. Usually, IAT coolants last for two years or 30,000 miles.
HOAT or Hybrid Organic Acid Technology contains a little amount of silicate and no phosphate. This coolant is suitable for aluminum-blocking engines and has a lifespan of 150,000 miles or five years.
Non-toxic coolants have a lifespan of 36,000 miles or three years. This coolant uses propylene glycol instead of ethylene glycol. This coolant is environmentally friendly and safe to use.
Car Coolant Frequently Asked Questions
- The engine should be running while removing the coolant in my car radiator?
No, the engine should not be running while removing the coolant from the radiator, but, once you have drained the coolant, you should start the engine before refilling the coolant. Yes, before refilling the coolant, start the engine to remove all the air present in the radiator. The presence of air in the cooling system would lead to pressure build-up, which would eventually, lead the blown away gasket.
- How long before I could drain the coolant and add new coolant after a trip?
The most important thing that you should know before draining or refilling the coolant is that radiator and engine should not be hot. If you find them hot, wait until they cool down. Draining and refilling coolant in a car is not something to be done carelessly if you try to drain the hot coolant, there is a high chance that it could splash on your body and cause burns. A cool engine and radiator are best recommended for draining and refilling the coolant.
- Is it okay if I use water instead of dedicated coolant fluid?
Water is a natural coolant, however, using water in a car cooling system is a stupid thing to do. It would destroy the cooling system slowly, remember, water could lead to rust development and they boil very fast and turn into steam. This could build-up pressure and kill the cooling system. A dedicated coolant is formulated to boil very slowly and also to prevent rust or corrosion. Therefore, never use water as an alternative to coolant fluid, if your car is warrantied, this simple action of yours could void the warranty.
- How often should I top up coolant fluid?
The frequency of topping-up coolant fluid depends entirely on the car manufacturer and the frequency of your car use. In general, most car manufacturers recommend checking and topping up coolant oil, twice every year. But, we recommend that you check the coolant level once every 3 months and if you find the coolant oil fell below the guide marks, refill it.
- The coolant reservoir of a car should be always full?
No, the function of a coolant reservoir is to store the excess coolant fluid until the cooling system requires it. In general, the coolant reservoir should be 30% full, and anything above this level while the engine is off and cool is unfavorable to the coolant system.
- An antifreeze fluid and coolant fluid are the same? is there any difference between the two?
Yes, there is a difference. Antifreeze fluid is a concentrated form of coolant fluid. An antifreeze fluid if diluted with water would become a coolant fluid. This is what is the key difference between the two.
- My coolant fluid has a brown/black color, is it okay? Is it time to change it?
The healthy color of the coolant oil is green or orange. If the color of the coolant fluid is anything other than this, then it is time to replace the coolant. A black/brown color coolant fluid is inefficient.
Coolants are ideal for enhancing the lifespan of any car and allow it to run optimally. These fluids can prevent corrosion and rust of the metal parts in your car engine and maintain the heat accurately. This article contains the best coolants for cars. You can choose any coolant from this article if you think that can improve your car’s performance.
