10 Best Car Coolants in the Philippines 2022 | Prestone, Toyota, Honda, and More

An engine coolant is used to regulate the boiling and freezing point of your car's cooling system. More so, a radiator coolant protects the engine and cooling system from rust and corrosion, ensuring your car lasts longer and performs better. In our tropical climate, overheating is always a concern and is something that can lead to more car expenses.


Periodic car maintenance is essential for keeping your ride in tip-top shape. However, you must be sure that you order the right coolant type, mix the right ratio, and choose the best additives specific to your vehicle’s make and model. We created a buying guide for you to know how to choose the best one. And, we have prepared a list of the best ones you can buy as well.

How to Choose a Car Coolant - Buying Guide

Keep your car running in ideal condition by periodically changing your radiator coolant. Over time, the chemicals in them break down, rendering them less effective. Choosing the best coolant depends on several factors, and we are here to inform you how to choose the best one for your car below.

Don’t Pick a Coolant Based on Its Color

Don’t Pick a Coolant Based on Its Color

Let's get our facts straight first, coolants are colorless, while the green, pink, blue, yellow, and other colored coolants you see are dyed by their manufacturers. Yet, the colors are not just for appearance, and there are several reasons why you see coolants available in a rainbow of colors.


First, the reason why they have a luminous color is to make it easier to see the coolant level when you pop the car's hood. Second, most manufacturers produce more than one type of radiator fluid; the difference in color lets you distinguish a brand's formula from another. Lastly, having different-colored coolants unconsciously forces you to be mindful of what you put into your car.


The best coolant for your vehicle should not depend on the color. Read on for a detailed yet worthwhile guide on how to pick the best coolant formulation for your tsikot.

Determine the Type of Coolant Your Car Needs

There are different types of engine coolants, each is specifically engineered for different types of cars. Coolant manufacturers also consider the climate of an area when formulating their coolants. Hence, it is important to always use the type recommended for your vehicle.

IAT Coolants for Overall Metal Protection

IAT Coolants for Overall Metal Protection

Inorganic Acid Technology (IAT) coolants are usually green in color. IAT coolants are commonly used in older cars, those produced in the 90s and below. The additives are specifically geared towards preventing rust and corrosion for steel-based engines. It has an ethylene glycol base, with silicate, phosphates, or both as additives to prevent corrosion.


IATs work by lining all metal parts with layers of additives for corrosion protection. The main reason why this is the most preferred for older models is that IAT was the only coolant formula available during those times. This is why this has become the conventional coolant type. And for most car owners, if it worked well, then it would work well now.

OAT Coolants for a Well-Targeted and Longer Protection

OAT Coolants for a Well-Targeted and Longer Protection

Organic Acid Technology (OAT) coolants are usually colored yellow or orange. OATs are designed for newer cars made in the 2000s and later. They use organic acids as corrosion inhibitors, specifically carboxylates. Hence, they have no silicates and phosphates.


If IATs coat every part, OATs work by specifically targeting potential corrosion areas when needed. They chemically interact with the metal surfaces to protect and get rid of potential problems.


Long-life carboxylate-based coolants were created to meet global standards; hence, they provide the best performance over other formulations. This is why they have gained international popularity. OAT coolants work best for modern engines. And, they've been shown to work quite well with older ones as well. These engine coolants give your car unmatched corrosion protection for longer intervals.

HOAT Coolants Offer the Best of Both Worlds

HOAT Coolants Offer the Best of Both Worlds

The formulation of HOAT coolants is a combination of IAT and OAT formulas. It uses both organic acid and silicates to prevent corrosion of aluminum-based engines. HOAT coolants have fewer conductive additives which lower the risk of affecting your car’s electrical components. Below are its three sub-types:

  1. Phosphated HOAT – uses phosphates and organic acid, usually pink or blue; usually recommended for Asia-manufactured vehicles; Asian car manufacturers prefer this type of coolant because it uses phosphates and carboxylates that are best for heat transfer.
  2. Phosphate-Free HOAT – uses carboxylates; does not contain phosphates; low-silicate additives; phosphate-free to prevent hard-water scaling and is safer for gaskets and seals.
  3. Silicated HOAT – uses silicates; not the best for effective heat transfer, hence, the least preferable choice for cars in the Philippines.

Look for Phosphate Additives for Engine Overheat Protection

Look for Phosphate Additives for Engine Overheat Protection

Additives are used by coolant manufacturers for two reasons: to increase the boil and freeze point of water and to ensure the best heat transfer. The three main additives are silicate, phosphates, and carboxylates.


Each of these anti-corrosives is not better than the other. But there is such a thing as “regional preference.” Some additives are better used in Asian countries, and some better for the climates of Europe or the United States.


Let’s focus only on Asia, specifically the Philippines. Being a tropical country, the biggest problem that we have with our cars’ cooling systems is overheating. As such, phosphate additives are the best choice; they offer the best heat transfer. Therefore, the best type of coolant for use in our country is a high-quality phosphate HOAT coolant.

How to Change Your Radiator Fluid

Check your car manual to know when to change your coolant. It can range from every 50,000 to every 150,000 kilometers. Do a visual inspection instead, if your coolant has some funky look or orange tint to it, then it's time to replace it. Since coolants are typically inexpensive, you can even do a yearly flush.


How do you replace your radiator fluid? Engineering Explained answers that in the video above. Their Youtube channel is a go-to for all things car-related, from the engine, suspension, cooling system, body, and virtually everything else. We summarize the steps and important tips for changing your radiator fluid below.

How to Change Your Radiator Fluid
  1. Make sure your temperature control is on maximum heat. This opens up the heater core, ensuring you can drain all the coolant in the system. 
  2. The car should be cool before you proceed with removing the caps and plugs of your cooling system.
  3. Remove the radiator cap, but let the cap rest loosely on the hole so no contaminants get in. Removing the radiator cap allows air to flow in, making draining the coolant quicker.
  4. Next, loosen the radiator drain plug. It is usually located at the bottom left or right of the radiator. 
  5. Locate and remove your engine drain bolt. This drains the coolant stuck in the engine block and the heater core. Note, always use a thread sealant when reinstalling this drain bolt.
  6. Drain and clean the coolant reservoir. Make sure there are no sediments and other contaminants inside before reinstalling.
  7. Refill the reservoir without exceeding the max line.
  8. Now, top up the radiator with the coolant. Do not put the cap on just yet. Turn on your engine and let it idle, doing this lets all the air stuck in the cooling system make its way out. This process is called bleeding the radiator. Add coolant as needed. After, screw on the radiator cap.

Most car maintenance tasks can be done at home, as long as you have the right tools, equipment, and knowledge. Having a proactive approach to your maintenance will make sure that your car is always in pristine running condition. And, a well-running car makes for a happy and safe driver.


Never forget the periodic fluid changes that need to be done, engine oil, radiator coolant, transmission oil, differential oil, brake fluid, clutch fluid, even your washer fluid. They might seem like a lot to take note of but remember that an ounce of prevention is better than spending half your car’s value on a “cure”.
