Best Homemade Radiator Flush

Car radiators are meant to keep a car’s engine running at a safe temperature. The radiator’s antifreeze keeps the engine cool while also acting as a filter for certain pollutants in the engine block. The antifreeze in your car should be replaced every 50,000 miles. At this point, you should also clean the radiator. The radiator may be cleaned without the use of any special products. A quick and easy best homemade remedy would suffice.

Tools Required

  • Funnel
  • Large drain pan
  • Screwdriver

When you need Radiator Flush?

Determine whether your radiator genuinely needs to be cleaned before you start making your radiator cleaner. The only time a radiator has to be cleaned is if your mechanic advises it. While flushing was once essential since radiators were constructed of steel and other readily corroded metals, most current automotive radiators are made of Aluminum, which eliminates the need for flushing.

Ideal Time to Flush Car Radiator

Before you touch anything near the radiator, make sure the engine is absolutely cold. You might receive terrible burns on your hands and face if you don’t let the automobile cool fully. The optimum time to do the cleanse is first thing in the morning before getting in the car.

Here are the Steps of the Best Homemade Radiator Flush:

Locate the Radiator

  • Look for a flat, finned metal region towards the front of your car when you lift the hood. The radiator may be found here.
  • Look for a spherical metal cap that leads to the radiator. It might be labelled “radiator coolant” or something like.

Note the cap’s location, because you’ll be adding fluids to it later.

Drain the Radiator

  • Crawl beneath the car and seek for a valve or a large-diameter rubber hose connected to the radiator and held in place by a detachable clamp.
  • Place your drain pan right beneath the valve or hose clamp, then open or loosen the valve or clamp.
  • Leave the radiator draining for at least 10 minutes or until only a slow drip of antifreeze remains.

Now It’s Time to Flush the Radiator

Tip: All you actually need is distilled water to generate an excellent cleaning solution. Because tap water includes mineral residues that might interact with the antifreeze and cause difficulties in the radiator, it is not recommended for this project. Most supermarket stores and home supply businesses sell distilled water. Make sure you don’t buy mineral water by accident. The only cleaning component you’ll need to cleanse the radiator system is distilled water.

  • Replace the hose and tighten the clamp keeping it in place, or, if your car has one, close the radiator drain valve.
  • Remove the radiator cap and fill the radiator with distilled water until it is completely filled.
  • Start the car and let it run for 10 to 15 minutes after replacing the cap.
  • Shut off the vehicle, then open the valve or loosen the hose again, draining all the distilled water and filth from inside the radiator into your drain pan.
  • Retighten the clamp or close the valve, then slide the full drain pan out of the way.

The Last Step is to Refill Radiator

  • Refer to your owner’s manual to see how much coolant (antifreeze) your radiator needs.
  • Open the radiator cap you found earlier, insert your funnel into the inlet, and fill the radiator with a 50/50 mixture of concentrated antifreeze and distilled water.
  • Check the overflow tank for coolant and add as needed until the level reaches the service line. The overflow tank is made of plastic and has a little flexible line that connects it to the radiator.
  • Check for leaks by starting and running the vehicle for several minutes. If everything appears to be in order, you should be able to skip this step for the next 100,000 kilometers.

Last Check

  • Turn off the car and add a bit more antifreeze and water until you notice it starting to emerge in the overflow tank’s bottom.
  • Open the overflow tank cap, then top it off with distilled water and a bit more antifreeze, aiming to stop a couple inches below the service line, and you’re done!
