How to Change Your Car’s Engine Coolant

Introduction

Engine coolant is a vital fluid that helps keep your car’s engine running smoothly. It circulates through the engine block and radiator, absorbing heat from the engine and dissipating it into the air. Over time, coolant can become contaminated with debris, lose its effectiveness, and need to be replaced. Changing your car’s engine coolant is a relatively simple task that can be completed in about an hour.

Safety First

Before you begin working on your car, it’s important to take some safety precautions. Park your car on a level surface and engage the parking brake. Allow the engine to cool down completely before you start working. Wear gloves and eye protection to protect yourself from hot coolant and debris.

Materials You’ll Need

• New engine coolant
• Funnel
• Bucket or drain pan
• Wrench or socket set
• Rags or towels

Step-by-Step Instructions

1. Locate the Radiator Cap

The radiator cap is typically located at the top of the radiator. It may be black or colored and will have a symbol of a fan or radiator on it.

2. Remove the Radiator Cap

Carefully loosen the radiator cap by turning it counterclockwise. Do not remove the cap completely until the pressure has been released. Once the pressure has been released, you can remove the cap.

3. Drain the Coolant

Place the bucket or drain pan under the radiator. Locate the drain plug at the bottom of the radiator and loosen it with a wrench or socket set. Allow the coolant to drain out into the bucket or drain pan.

4. Close the Drain Plug

Once the coolant has drained out, tighten the drain plug back into place.

5. Fill the Radiator with New Coolant

Using a funnel, pour the new engine coolant into the radiator. Fill the radiator to the “full” mark.

6. Replace the Radiator Cap

Tighten the radiator cap back into place by turning it clockwise.

7. Check the Coolant Level

Start your car and let it idle for a few minutes. Allow the engine to reach operating temperature. Turn off the engine and wait a few minutes for the coolant to cool down. Check the coolant level in the radiator and add more coolant if necessary.

Tips

• Use the type of engine coolant that is recommended for your car.
• Flush the cooling system with water before adding new coolant. This will help remove any debris or contaminants from the system.
• Dispose of used coolant properly. Do not pour it down the drain or into the environment.
• Change your car’s engine coolant every 2 years or 30,000 miles, whichever comes first.

Conclusion

Changing your car’s engine coolant is a simple task that can be completed in about an hour. By following the steps outlined in this guide, you can keep your car’s engine running smoothly and prevent costly repairs.
