What Is Car Coolant and Why Replace It?
Coolant is a liquid that keeps your car’s engine from getting too hot. It’s like a cold drink for your car!
Why Coolant Matters
Coolant moves heat away from the engine to the radiator. It also stops freezing in winter and protects parts from rust.
Why Replace It?
Old coolant gets dirty and weak. Replacing it prevents overheating and engine damage.
Tools and Materials You’ll Need
You don’t need fancy tools to replace coolant. Here’s what I use:
- Coolant (antifreeze): Check your car’s manual for the right type.
- Distilled water: Mix with coolant for best results.
- Drain pan: Catches old coolant safely.
- Funnel: Helps pour new coolant neatly.
- Gloves and rags: Keeps your hands clean and safe.
- Wrench or screwdriver: For removing drain plugs or hoses.

Here’s my step-by-step guide to change coolant. Follow along, and you’ll be done in no time!
Step 1: Stay Safe
Always work on a cold engine. Hot coolant can burn you!
Step 2: Find the Radiator and Drain Plug
Look under the hood for the radiator. The drain plug is usually at the bottom.
Step 3: Place the Drain Pan
Put the drain pan under the plug. This catches the old coolant.
Step 4: Drain the Old Coolant
Open the drain plug with a wrench. Let all the coolant flow out.
Step 5: Flush the System
Pour distilled water into the radiator. Run the engine for 10 minutes, then drain again.
Step 6: Mix New Coolant
Mix coolant with distilled water (50/50 ratio). Use a clean container.
Step 7: Fill the Radiator
Use a funnel to pour the mix into the radiator. Fill to the “max” line.
Step 8: Bleed Air Bubbles
Run the engine with the cap off for 10 minutes. Add more coolant if needed.
Step 9: Check for Leaks
Look for drips under the car. Tighten plugs if needed.
Step 10: Dispose of Old Coolant
Pour old coolant into a sealed container. Take it to a recycling center.

Coolant is a liquid that cools your car’s engine. It stops overheating and freezing. Mix it with water for best results. Always use the type your car’s manual suggests.

Replace coolant every 30,000 miles or 2-3 years. Check your manual for exact timing. Old coolant loses its power and can harm your engine.
Can I Use Water Instead of Coolant?
Water works in an emergency but isn’t ideal. Coolant has special additives to prevent rust and freezing. Use a 50/50 coolant-water mix for safety.
How Do I Know If My Coolant Is Low?
Check the reservoir tank under the hood. If it’s below the “min” line, add more. A warning light on your dashboard may also signal low coolant.

Yes, if you follow safety steps. Work on a cold engine and wear gloves. Dispose of old coolant properly, as it’s toxic to pets and people.
What Coolant Type Should I Use?
Your car’s manual lists the right coolant. Common types include OAT for general use or phosphate-based for Japanese cars. Don’t mix different types!
Why Does My Car Overheat After a Coolant Change?
Air bubbles in the system can cause overheating. Run the engine with the cap off to bleed air. If it persists, check for leaks or get a mechanic’s help.
