Keyword: best coolant for cars in extreme heat Bangladesh
With Bangladesh's summer temperatures soaring above 40°C in many regions, choosing the right coolant for your vehicle becomes more than just maintenance—it's a necessity. Engine overheating is one of the most common causes of vehicle breakdowns during hot weather. In this guide, we’ll explore the best car coolant options available in Bangladesh, what makes a coolant suitable for extreme heat, and how you can protect your engine from overheating effectively.
Why Coolant is Crucial in Bangladesh’s Hot Climate
Coolant, often referred to as antifreeze, plays a vital role in regulating engine temperature. In extreme heat, especially in places like Dhaka, Chattogram, or Rajshahi, an efficient coolant keeps your engine cool, prevents rust, and protects the radiator system.
Without a proper coolant mix, your engine can overheat quickly in traffic or during long drives, resulting in costly damage. That’s why selecting a high-performance coolant is essential for car owners in Bangladesh.

FAQs: Best Coolant for Cars in Extreme Heat Bangladesh
1. What is the best coolant for Bangladeshi cars?
Brands like Shell Ultra, Prestone, and Liqui Moly are popular for their superior heat tolerance and compatibility with both petrol and diesel engines.
2. Can I use water instead of coolant?
Using plain water is not recommended for long-term use. Water lacks anti-corrosion and heat transfer properties that proper coolant provides.
3. How often should I change my car's coolant?
It’s best to change coolant every 1–2 years depending on the vehicle and the coolant type. Always refer to your owner's manual.
4. Is it okay to mix different brands of coolant?
Generally not recommended. Mixing different types (OAT, HOAT, IAT) can cause chemical reactions that reduce efficiency and damage your cooling system.
5. Why is my car overheating even with coolant?
This may indicate other issues like a faulty thermostat, radiator fan failure, or coolant leakage. Read more about car overheating causes here.
