Flush Your Cars Radiator Properly

1. Make your car ready for radiator flush

First, you can prepare your car accurately for the radiator flush to ensure there is no issue in the middle of the process. In the first step of flushing the radiator, you need to remove the coolant from your car’s cooling system. As the antifreeze or coolant is dangerous for your skin, you should take proper precautions to do the process safely. You can use safety goggles and gloves to keep your eyes and skin safe from the coolant.

While removing the coolant, you should ensure that the car engine is cool. If you recently used your car, then you need to allow it to cool down before starting the flushing process. Generally, 30 to 40 minutes is enough to cool down your car’s engine.

Now, you can use a jack to lift the front part of your car and access the drain plug. You can use an appropriate container to keep the engine coolant that you remove from your cooling system. Also, you can check the manufacturer’s manual to check the capacity of your car’s cooling system. By doing this, you can have an idea of how much coolant you need to collect in the container and choose the right size of the container.

2. Remove the coolant from your car’s cooling system

After you make your car ready for the radiator flush, you can proceed for draining the engine coolant. First, you can remove the pressure cap of your radiator. While doing this, you can use a clean rug on the top of the radiator for safety. If the coolant inside the radiator is still hot, then you can be safe from that by using the rug. You can also remove the cap of the engine coolant reservoir to remove the coolant from that.

After opening both the caps, you can go under your car and locate the drain plug. Then you can take the correct size of the container and place it under the drain plug to collect the coolant. Now, you can release the drain plug using a screwdriver to collect the engine coolant. If you don’t know how to open this plug, you can follow the manufacturer’s manual to open it correctly. Once it is opened, you can collect the coolant in the container and close the drain plug again.

3. Flush your car’s radiator

Now, you can clean the radiator before putting the new coolant. For cleaning the radiator, you can use a radiator cleaner. Before putting this cleaner, you should ensure that the drain plug is closed. Otherwise, this cleaner will get drained to the ground directly. After pouring the radiator cleaner, you can pour the right amount of distilled water into your radiator and close the radiator cap tightly. Now, you can start your car and let it run for at least five to ten minutes idly. In this process, the radiator cleaner and water will get circulated in the cooling system and engine to remove the unwanted items from your system. Also, you should do this process in a ventilated place to ensure the exhaust gases are removed from the area properly.

Then you can let the engine cool down for 30 to 40 minutes. When the engine gets cooled, you can open the radiator cap and drain plug to remove the liquid from the radiator. This time, you may get brown colored liquid which is mixed with the harmful chemicals. You can repeat this flushing process until you get clean liquid from the radiator. Generally, you can repeat this flushing process two or three times if you flush your car’s radiator in every two years.

4. Put new coolant in the radiator

When you notice that the radiator is cleaned, you can put a new coolant into the radiator. You can check your manufacturer’s manual and ensure to pour the right amount of coolant into your car’s radiator. Also, you need to make sure to use the right type and ratio of coolant recommended by the manufacturer.

Now, you can start the engine and let it run for at least 10 to 15 minutes to allow the new coolant to circulate throughout the cooling system. Then you can wait for at least 30 minutes to cool down the engine again. Once the engine has cooled, you can open the radiator cap and check the coolant level is decreased or not. You can add more coolant if the coolant level is decreased in the radiator.

Conclusion

Flushing your car’s radiator is an important part of your car’s maintenance. Also, you can do this process by following the right steps easily. Though the flushing of your car’s radiator takes more time, you must do this process to maintain your engine health.
