How to Flush and Change Coolant in 9 Easy Steps

How to Flush and Change Coolant in 9 Easy Steps | Funk Bros Auto

Are you noticing your car's engine running hotter than usual or experiencing coolant leaks? It might be time to flush and change your coolant. While it may seem daunting, performing a coolant flush and change is a straightforward process that can be done at home with minimal tools and expertise. How? Follow the steps below and find out!

  1. Gather Your Materials

Before you begin, gather all the necessary materials, including:

  • New coolant
  • Distilled water
  • Drain pan
  • Funnel
  • Safety gloves
  • Safety glasses

It's essential to use the correct type of coolant recommended for your vehicle to ensure compatibility and optimal performance.

  2. Prepare Your Vehicle

Park your car on a level surface and allow the engine to cool completely. Make sure the vehicle is in park or neutral and engage the parking brake for added safety. Open the hood and locate the radiator and coolant reservoir.

  3. Drain the Coolant

Place the drain pan underneath the radiator drain plug and carefully loosen the plug using a wrench. Allow the old coolant to drain completely into the pan. Once drained, tighten the drain plug securely.

  4. Flush the Cooling System

Fill the radiator with distilled water and replace the radiator cap. Start the engine and let it run for a few minutes to circulate the water through the cooling system. Then, turn off the engine and allow it to cool again.

  5. Repeat the Flushing Process

Repeat the flushing process two to three times or until the drained water runs clear. This will help remove any remaining debris or contaminants from the cooling system.

  6. Mix Coolant and Water

Once the system is flushed, prepare the coolant by mixing it with distilled water according to the manufacturer's instructions. Use a 50/50 mixture of coolant and water for most vehicles, but refer to your owner's manual for specific recommendations.

  7. Refill the Cooling System

Carefully pour the coolant mixture into the radiator until it reaches the top. Then, fill the coolant reservoir to the proper level as the markings indicate.

  8. Bleed the Air

To remove any trapped air bubbles from the cooling system, start the engine with the radiator cap off and let it run for a few minutes. Keep an eye on the coolant level and add more if necessary.

  9. Check for Leaks

Finally, inspect the cooling system for any signs of leaks or abnormalities. Tighten any loose connections and ensure all components are properly seated.

  Questions & Answers

How often should I flush and change my car's coolant?

It's recommended to flush and change your coolant every 30,000 to 50,000 miles or every two to five years, depending on your vehicle's make and model.

Can I use tap water instead of distilled water for mixing coolant?

While tap water can be used in a pinch, distilled water is preferred for mixing coolant as it is free from impurities and minerals that could potentially harm your cooling system.

What are the consequences of neglecting coolant maintenance?

Neglecting coolant maintenance can lead to overheating, engine damage, and costly repairs. It's essential to stay proactive and address any cooling system issues promptly.
