How Flushing Works For Car Radiators

Your car’s radiator may develop a build-up of dirt, grease and other sticky substances that may clog up its heater core. This is why expert mechanics at advise that you have a radiator flush or in layman’s term, a cooling system flush to keep your vehicle in good condition.

Flushing helps clear the vehicles’ cooling system and maintain its normal temperature while on the road. This process helps clear your vehicle’s cooling system and ensures that your radiator will not have gunk that might block the entire system, causing engine failure. Expert mechanics are trained to carry out this process, but it wouldn’t hurt if you also have ample knowledge on how it is done.

Knowing the rationale behind this process will help you understand why your vehicle needs to maintain its temperature at all times and in all weather conditions. Clearing your car’s cooling system will prevent damage caused by substance build-up. An engine coolant that is not mixed properly may cause corrosion of the radiator’s steel components. Although there are anti-freeze and corrosion inhibitors available nowadays, there is still no guarantee that gunk will not build-up over time. This gunk can get in the way of the radiator’s ports and may cause a blockage to the system.

The Cooling System Flush

There are several steps involved in doing a radiator flush or cooling system flush. They are as follows:

  • Step One: The radiator has to be drained out. A drain plug will have to be opened with a screwdriver.
  • Step Two: A catcher should then be added under the radiator to collect fluids that come out. This will ensure that the radiator will be fully empty and easier to wash out. Don’t forget to close the radiator again so the cleaner won’t leak prematurely.
  • Step Three: A cleaner must then be used to take care of the flushing process. A cleaner can be used to treat the radiator as you can get any buildups or other materials to become loose so the coolant in your radiator can actually move properly. The flush solution that you can use may be found in a car maintenance shop. You can add this into your radiator and then use clean water to complete the process.
  • Step Four: Drain the water and the flush solution same as in step one.
