Step 1: Determine Where the Leak Is

The first step is to determine where the leak is. One way to do this is to pour a little water on the ground near the car and watch for it to evaporate. If it does, that’s a good indication that the leak is coming from the cooling system. Another way to determine where the leak is located is to inspect the hoses and belts for damage.

Step 2: Prepare the Car for Repair

Once you have the supplies you need, it’s time to repair your car. The first step is to prepare it for repair. This means removing any items from the area you will be working on and putting down a cloth or tarp to protect the car’s finish. It’s also a good idea to disconnect the battery so that you don’t accidentally short anything out.

Step 3: Prepare to Remove the Radiator Cap.

Now that you have the proper tools, it is time to remove the radiator cap. Gather some rags and place them around the engine so that any coolant spills will be soaked up. Next, place the jack stands under the car and raise it. Finally, locate the radiator cap and twist it off. Be careful as coolant may spurt out. If any does, it will be caught by the rags. Allow the coolant to drain completely before proceeding.

Step 4: Add the Baking Soda and Dishwashing Soap

Once the coolant has drained, it’s time to add the baking soda and dishwashing soap. Pour the baking soda into the container or bowl and add enough water to make a thick paste. Stir until the baking soda is dissolved. Now add the dishwashing soap and stir again.

Step 5: Soak a Cloth in the Mixture

Rub this cloth over the area

Next, soak a cloth in the mixture and wring it out to not be too wet. Rub this cloth over the area where the leak is located. Be sure to avoid coming into contact with any coolants as they can be harmful. Continue rubbing until the cloth starts to dry out. Then re-soak it and continue rubbing.

Step 6: Rinse the Area With Water

Once you have rubbed the area with the cloth, it’s time to rinse it off with water. Pour a small amount of water over the area and use a sponge or brush to scrub it clean. Rinse until all of the baking soda and dishwashing soap are gone.

After cleaning the area, inspect it for damage. If there is any damage, you will need to repair it before putting the radiator cap back on. Reattach the radiator cap once the site is repaired and lower the car back to the ground. Be sure to dispose of any rags used in this process properly as they may contain harmful chemicals.

Step 8: Remove the Radiator.

With the radiator cap removed, the next step is to remove the radiator. Several bolts hold it in place. Loosen them all and pull the radiator free from the car. Be prepared for more coolant to spill out, so have your rags ready. If there is any debris or gunk on the radiator, clean it off with a soft brush before setting it aside.

Step 9: Add Stop Leak to the Cooling System.

Now that the radiator has been removed, it is time to add the stop leak. Pour it into one of the corners of the radiator and let it flow throughout the system. You will likely need to add more than one bottle, so have plenty on hand. It is essential to add the stop leak as soon as possible to help prevent further damage to the system.

Once the stop leak has been added, put the radiator back in place and refill the cooling system with fresh water.
