🧊 Coolant & Antifreeze Check: Preventing Engine Overheating

“Smoke is coming from the hood!” 😨

This scary situation often results from low coolant levels or neglected antifreeze.

 

🚨 Without proper maintenance:

❌ Engine overheating

❌ Cooling system damage

❌ Car won’t start

 

✅ With regular checks:

✔ Stable engine temperature

✔ Cooling system protection

✔ Longer vehicle lifespan

 

Let’s dive into how to check and maintain your coolant and antifreeze! 🚗

2. Coolant vs. Antifreeze: What’s the Difference?

ItemCoolantAntifreeze

Definition	Liquid to cool the engine	Additive to prevent freezing
Purpose	Maintain engine temp	Improves coolant performance
Usage	All seasons	Especially important in winter
Composition	Water + antifreeze	Ethylene glycol-based

 

• Antifreeze is a key component of coolant and helps regulate the freezing and boiling points.

3. How to Check Coolant Levels

 

✔ 1) Check Coolant Reservoir

 

• Open the hood and inspect the coolant reservoir
• Level should be between ‘LOW’ and ‘FULL’ marks
• Always check when engine is cool!

 

✔ 2) Check Color

 

• Normal colors: green, pink, blue
• If it turns brown or gray, it may be contaminated

 

✔ 3) Check for Leaks

 

• Look under the car for colored liquid leaks
• Inspect radiator, hoses, and water pump areas

 

✔ 4) Replace Regularly

 

• Change every 2–3 years or 40,000–60,000 km
• Always refer to your car’s manual

4. Antifreeze Maintenance Tips

 

✔ 1) Maintain Proper Ratio

 

• Mix 50:50 antifreeze and water
• Pre-mixed coolants are also available

 

✔ 2) Seasonal Care

 

• Winter: Prevent freezing
• Summer: Prevent overheating

 

✔ 3) Use Correct Type

 

• Check manufacturer’s recommendation
• Colors can be misleading—check the formula!

5. FAQ: Coolant & Antifreeze

 

Q. Can I top off coolant with just water?

A. It’s not recommended. Without antifreeze, it may freeze or overheat.

 

Q. Is too much antifreeze bad?

A. Yes, improper ratios reduce cooling efficiency.

 

Q. Can I change it myself?

A. You can, but it’s tricky—air bubbles and proper disposal are issues. Better to visit a pro.
