10 Best Car Coolants in the Philippines 2023 | 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.

1

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.

Type 1 Formula for Older Honda Models

This green coolant is the original formula of Honda for the cooling system of their vehicles. It was designed for their older models such as the first-gen Civics until the 6th gen ones, the first-gen CR-Vs, and Accords produced up to the early 2000s.


It has an IAT formula, meaning it uses inorganic acids. As they are Asian-manufactured vehicles, they most probably contain phosphate instead of silicate. But, we can only presume such since Type 1's formula is a proprietary secret.


Go visit the casa and they'll require the Type 1 if you have an early 2000s and below model. This is because, as mentioned above, they are designed specifically for older Honda engines.

If you happen to own a Mazda, Ford, Suzuki, Subaru, Nissan, Hyundai, or Honda that require FL22 coolants, then you clicked on the right article. This phosphated HOAT coolant will keep your car away from overheating, rusting, and scaling.


This FL22 coolant is made for cars with stringent coolant requirements. Truth be told, any universal long-life HOAT coolant would do as an FL22 replacement.

This Ravenol product comes in a huge 5-liter jug. That's usually enough for a top-up after a complete flush, with a little more extra for when your reservoir runs dry.
