And while you’re thinking of hitting the road, heading to long drives, going on a beach trip to Goa by car, the car doesn’t seem to be having much fun. Hotter temperatures can stress the engine, causing it to overheat, which in turn leads to breakdowns and catastrophic repair bills.
The proper use of a car coolant will protect you against suffering through summer heat. Need car service in Mumbai, you must choose the right coolant for the car service. With so many choices, you must figure out which will work best for you. Read on to learn why coolant is necessary and how you should buy the one that fits you best for top coolants for summer that save your engine.
Why Coolant Matters in Summers
The engine of your car runs at elevated temperatures, and without effective cooling it would heat up quickly. The coolant, which is also known as antifreeze, travels the engine and takes away the excess heat and stops metal parts from sticking or warping.

What Is the Problem with Using a Wrong Coolant?
Using the incorrect coolant brand or failing to do coolant maintenance properly will lead you to face major issues like:
- Overheating due to low cooling can damage the engine.
- Corrosion - Certain coolants do not like some metals and make rust.
- Clogging - Combining incompatible coolants will cause sludge to form, which insulates cooling passages.
A top car repair service in Mumbai can help you choose the best coolant and keep your car in good shape.
Different Coolants and How They're Not the Same
All coolants aren't alike. Here are the main kinds:
1. Inorganic Acid Technology (IAT)
Old-school green coolant used in older cars. Has phosphates and silicates to stop rust. Needs changing often (every 30,000 miles or 2 years).
2. Organic Acid Technology (OAT) orange, red, or dark green
Used in lots of new cars. Lasts longer (up to 150,000 miles or 5 years). Stops rust better without using silicates.
3. Hybrid Organic Acid Technology (HOAT) A blend of IAT and OAT coolants
Found in many European and Asian cars. Often yellow, pink, or blue. Gives long-lasting defense and better heat removal.
4. Extended Life Coolant (ELC) Made for heavy-duty vehicles
Gives top-notch protection to diesel engines. Stays effective longer than regular coolants. If you want to find car servicing close to you in Mumbai, be sure to ask experts about the right coolant for your car.
