Overview

  • Philippine drivers face unique cooling system stresses from heat and traffic, making proper coolant maintenance vital to avert engine damage. 
  • Key practices include regular level checks on cooled engines, avoiding tap water to prevent deposits, selecting the right type per vehicle specs and adhering to replacement schedules. 
  • TGC One Hub supplies premium options such as PRO99 Long Life Coolant and ROTELOS Heavy-Duty for reliable protection.

Introduction

Have you ever recognized your car's temperature gauge rising or wondered what keeps your engine from overheating during long travels? It's car coolant. Drivers may not think about it often, but it's also known as antifreeze, a liquid solution that circulates through the engine to regulate temperature. 

It absorbs heat from the engine and releases it through the radiator. Simultaneously, it helps safeguard engine parts from corrosion, rust, and intensive thermal shifts, especially in the Philippine climate.

In this guide to car coolant, we explore the significant concepts of this fluid to better understand their types, practices, and even the right supplier in the country.

Key Coolant Practices for Philippine Driving

Driving situations in the Philippines can put additional stress on your car's cooling system. Because of this, correct coolant maintenance becomes even more crucial to prevent intense heat and engine damage.

Inspect Levels Consistently

Make sure your engine is cool before opening the hood. Locate the coolant reservoir, a transparent plastic tank with "MIN" and "MAX" markings on the side. If the coolant is below the minimum line, it's time to top it up using the suggested coolant for your vehicle. 

Do not use plain water unless it's urgent. It's also wise to check for sudden drops in level, as this may signal a leak or cooling system problem. Doing this regularly can help avoid overheating or recurring repairs.

Do Not Use Tap Water

Avoid using tap water as an alternative for coolant in your vehicle, as it contains minerals and impurities that can gradually build up inside the cooling system. These deposits can result in blockages, corrosion,  and inefficient cooling. 

Instead, always use the recommended coolant or a correct coolant-water mixture distinguished for your car. If you need to dilute it, use distilled water, as it's free from minerals that can damage the system. Using the correct fluid helps safeguard your engine and guarantees the cooling solution works appropriately.

Choose the Right Coolant

Not all coolants are the same, they differ in formulations, additives, and suitability based on the car type and manufacturer suggestions. To choose the most fit, review your vehicle's manual or adhere to the recommended coolant type and specifications. Using the wrong one can lead to weak performance, corrosion, or damage to engine parts.

Therein, it's crucial to avoid combining different kinds of coolant unless specified, as this can reduce their efficiency. Selecting an adequate coolant ensures good temperature control and lasting engine protection.

Consider Replacement Interval

Car coolant gradually breaks down and loses its ability to safeguard your engine. That's why following the standard replacement interval stated in your car manual, based on time or mileage, is essential. 

To practice, have it inspected consistently and replaced when it becomes dirty, discolored, or less efficient. Delaying replacement can result in overheating, corrosion, and low cooling performance. Keeping track of its schedule, then, helps maintain a healthy engine.

Ensure Safety Warning

Do not open the radiator cap or coolant reservoir while the engine is hot, as it's still under pressure and can release scaling liquid or steam that may cause burns. Make it a habit to let the engine cool down completely before checking or adding coolant. 

Additionally, manage it thoroughly and keep it far from children and pets, as it can be hazardous if ingested. Practicing these safety protocols helps prevent accidents and ensures secure maintenance.

Common Coolant Colors and Types

Car coolants come in various colors and kinds, and these distinctions are more than just aesthetics. Every type is formulated with certain additives designed for engines and performance requirements.

Inorganic Additive Technology (IAT)

Color: Green

It's a traditional coolant that utilizes inorganic additives to safeguard engine parts from corrosion and rust. It's typically used in older cars and offers good yet shorter-term protection compared to newer coolant types. It calls for persistent replacement, often every 2 years as recommended.

Organic Acid Technology (OAT)

Colors: Red, Pink, and Orange

It's a modern type of coolant that leverages organic acids to deliver lasting protection against corrosion and rust. It's used in newer vehicles and commonly has a longer service life, lasting up to 5 years or more. Additionally it also provides greater safeguard for engine elements, but it must not be blended with other kinds of coolant to keep its effectiveness.

Hybrid Organic Acid Technology (HOAT)

Colors: Blue and Yellow

It combines organic acids with inorganic additives, providing protection and corrosion resistance. HOAT is used in a variety of contemporary cars, which delivers a balance between longevity and performance.

This type of coolant has a longer lifespan and provides superior safeguard for metal parts. But it's important to take note to avoid combining it with incompatible coolants to keep its optimal efficiency.

Important Note: Coolant color is a helpful guide, but it must not be the only basis for picking a coolant. Different manufacturers may use parallel hues for diverse formulations, so basing on color alone may result in using the wrong type.

Steps to Top Up Coolant

To know more of the correct usage of car coolant, here’s the step by step instructions to follow:

  1. Park on a flat surface, turn off the engine, and let it cool down fully.
  2. Open the hood and locate the translucent reservoir tank.
  3. Review the level against the "MAX" and "MIN" markings.
  4. If low, fill with the precise pre-mixed coolant or a 50/50 mix of concentrate and distilled water.
  5. Inspect leaks if you need to top it up persistently.
