Step-by-step instructions for safely changing coolant

instructions for safely changing coolant

Locate Radiator Cap and Drain Plug:

Open the vehicle’s hood and locate the radiator cap. Be cautious, as the radiator can be hot.

Identify the radiator drain plug at the bottom of the radiator. You might need to raise the vehicle or remove a panel to access it.

Prepare Drain Pan:

Place the drain pan under the radiator drain plug to catch the old coolant.

Open Radiator Cap:

Carefully remove the radiator cap to release pressure. This will help the coolant drain more effectively.

Drain Coolant:

Use pliers or a wrench to loosen the radiator drain plug. Allow the old coolant to drain completely into the drain pan. Keep in mind that the coolant may still be hot.

Dispose of Old Coolant:

Transfer the old coolant from the drain pan to a suitable container for disposal. Make sure to follow local environmental regulations for proper disposal.

Flush the System (Optional):

If you’re changing coolant types or it’s recommended by your vehicle’s manufacturer, consider flushing the system with water to remove any remaining old coolant or debris. This step is essential when switching between incompatible coolant types.

Close the Drain Plug:

Tighten the radiator drain plug securely to prevent leaks.

Fill with New Coolant:

If using pre-mixed coolant, pour it directly into the radiator through the radiator cap opening.

If using concentrate, mix it with distilled water according to the manufacturer’s instructions, then pour the mixture into the radiator.

Safety Precautions:

Always prioritize safety. Allow the engine to cool completely before starting the flushing process to avoid burns.

Identify Drain Points:

Locate the drain points for the radiator and engine block. You might need to consult your manual or do some research to find these points.

Flush with Water:

Use distilled water to flush the cooling system. This helps remove any remaining coolant and debris. Pour water into the radiator and let it drain out through the drain points.

Repeat the Process:

Depending on the severity of contamination, you might need to repeat the flushing process multiple times until the draining water runs clear.

Use Flushing Agents:

Some vehicles might benefit from using a specialized flushing agent. Consult your manual or a professional to determine if this step is necessary.

Run Engine Briefly:

With the drain plugs closed, run the engine for a short time (following safety precautions) to circulate the distilled water through the system. This can help dislodge any remaining debris.

Drain Again:

Once the engine has cooled down, open the drain points again to allow the water to drain out.

Refill with Distilled Water:

Refill the cooling system with distilled water and run the engine briefly to circulate it. This helps rinse out any remaining contaminants.

Final Drain:

Drain the distilled water from the system one last time, ensuring that the draining water runs clear.

Add New Coolant:

After the system is thoroughly flushed, you can add the new coolant. If using concentrate, mix it with distilled water according to the manufacturer’s instructions before adding.

Bleed Air Bubbles:

Follow the instructions in your vehicle manual to properly bleed any air bubbles from the system after adding new coolant.

How To Flush And Replace Your Engine Coolant

Step 1: Gather Materials and Tools

  • New coolant (Check your vehicle’s manual for the recommended type and quantity)
  • Distilled water (if needed for dilution)
  • Drain pan
  • Socket or wrench set
  • Funnel
  • Safety gloves and goggles

Step 2: Locate the Radiator and Drain Plug

  • Open the hood and locate the radiator. It’s usually at the front of the engine bay.
  • Locate the radiator drain plug at the bottom of the radiator. It might be a plastic wing nut or a standard bolt.

Step 3: Drain the Old Coolant

  1. Place the drain pan under the radiator drain plug to catch the old coolant.
  2. Loosen the drain plug. Be prepared for coolant to start flowing out.
  3. Once the coolant has drained completely, tighten the drain plug back in place.

Step 4: Flush the System

  • Although it’s not strictly necessary, flushing the cooling system can help remove any built-up sediment and contaminants. You can do this by:
    1. Refilling the radiator with water.
    2. Running the engine with the heater on for a few minutes.
    3. Allowing the engine to cool down, then draining the water again.

Step 5: Refill with New Coolant

  1. Double-check your vehicle’s manual for the correct type and quantity of coolant.
  2. If your coolant needs to be mixed with water, use distilled water to avoid mineral buildup.
  3. Use a funnel to pour the new coolant into the radiator until it’s nearly full.
  4. Start the engine with the radiator cap still off and let it run. This will help any air bubbles escape from the system.
  5. Slowly add more coolant as needed while the engine runs. Keep an eye on the coolant level.

Step 6: Bleed the Air

  1. Turn on the heater to the highest temperature setting and the blower to the highest setting. This helps circulate coolant through the heater core.
  2. Gently squeeze the upper radiator hose to help release air pockets.
  3. Keep adding coolant until the level stabilizes, and there are no more air bubbles escaping.

Step 7: Secure the Radiator Cap

  • Turn off the engine and let it cool down.
  • Once the engine is cool, secure the radiator cap back in place.

Step 8: Check for Leaks

  • Start the engine and let it run for a while. Keep an eye out for any coolant leaks under the vehicle.

Step 9: Dispose of Old Coolant Properly

  • Old coolant is toxic and should be disposed of according to local regulations. Many auto parts stores have coolant recycling programs.
