Engine coolant for my car

What is Engine Coolant?

Engine coolant, also known as antifreeze, is a fluid that circulates through an automobile’s engine to regulate its temperature
and prevent overheating. It is typically composed of a mixture of water, antifreeze (ethylene glycol or propylene glycol), and additives to
protect the engine components from corrosion and wear.

Why is Engine Coolant Important?

Engine coolant plays a crucial role in the proper functioning and longevity of an automobile’s engine. Its primary purpose is
to:

• Prevent Overheating: Coolant absorbs heat from the engine’s combustion process and dissipates it through the
  radiator, preventing the engine from reaching excessively high temperatures.
• Protect Against Corrosion: Coolant contains additives that form a protective layer on engine components,
  preventing corrosion and premature wear.
• Lubricate Water Pump: Coolant lubricates the water pump, which circulates the coolant throughout the engine.

Types of Engine Coolant

There are two main types of engine coolant:

• Inorganic Additive Technology (IAT): IAT coolants have been traditionally used in older vehicles and offer
  basic corrosion protection. They typically last for 2-3 years or 30,000-50,000 miles.
• Organic Acid Technology (OAT): OAT coolants are designed for newer vehicles and provide enhanced corrosion
  protection. They contain organic acids that form a protective layer on engine components. OAT coolants typically have a longer
  lifespan of 5 years or 100,000 miles.

Choosing the Right Engine Coolant

When selecting the appropriate engine coolant for your car, it is essential to consult your vehicle’s owner’s manual. Different
vehicles require specific types of coolant based on their engine design and materials. Using the wrong type of coolant can harm your
engine.

Flushing and Replacing Engine Coolant

Engine coolant should be flushed and replaced periodically according to the manufacturer’s recommendations. Flushing removes built-up
deposits, contaminants, and old coolant, ensuring optimal cooling and corrosion protection. The frequency of coolant replacement varies
depending on the type of coolant used and your driving conditions.

Steps for Flushing and Replacing Engine Coolant:

1. Allow the engine to cool down.
2. Locate the radiator drain plug and drain the old coolant into a suitable container.
3. Close the drain plug and fill the radiator with a recommended coolant flush.
4. Start the engine and run it for 5-10 minutes until the flush circulates through the system.
5. Drain the coolant flush and thoroughly rinse the system with clean water.
6. Fill the radiator and coolant reservoir with the appropriate engine coolant.
7. Check the coolant level after driving for a few days and adjust if necessary.

Conclusion

Engine coolant is a crucial fluid that plays a vital role in the proper functioning and longevity of your car’s engine. By using the
correct type of coolant and maintaining it properly, you can prevent overheating, protect against corrosion, and ensure the optimal
performance of your vehicle.
