Now, let us understand in detail, how the car radiator flushing is done.

How to Flush a Radiator?

For a proper and successful radiator flush, you should have all the essential tools and equipment which is as follows:

  • Two gallons of antifreeze
  • Eight liters of distilled water
  • A garden hose with a nozzle
  • A drainage bucket
  • Sudsy water in a bucket
  • Eye safety goggles

Antifreeze, which contains glycol, is very essential in the car radiator flush process, because it does the task of saving the cooling system from rust and corrosion. The temperature of the system is not constant but fluctuates. Antifreeze protects the cooling system from temperature changes.

The most important thing to take care of, before you do the actual car radiator flush is to make sure that the engine of the car is cold. The water which is used for radiator flush is cold and it can damage the car engine. Thus, we conclude that you should not do a radiator flush, immediately after a long drive.

Now, use sudsy water which you have in your materials list for the purpose of cleaning the radiator. The nylon brush and sudsy water are used for removing particles, bugs and debris, which eventually get collected on the grill of the radiator. Do the scrubbing work in the direction of the radiator fins. The grill of the radiator will get completely cleaned from the particles and the debris on pouring water. Use a disposable pan for draining the coolant. This pan will be fitted under the car and hence its size should be noted carefully before using it. The radiator consists of a drain valve and the pan is positioned at its center.

The task cap is the lid of the radiator which keeps the engine temperature under control. The radiator consists of hoses at its top as well as at the bottom. Sometimes, the hoses and the clamps develop cracks and are leaky due to lack of maintenance. So, before you refill your radiator, replace the rusty and leaky hoses and clamps with good ones. Now, just unscrew the cock and collect the coolant into the pan and place the drain pan back under the cock after the fluid is completely drained. Insert the garden hose nozzle into the spout of the radiator, to flush it. Keep adding the antifreeze and water containing coolant as the water is draining into the pan. Check for any sort of leakage in the clamps, cock or the drain pan. By keeping the cap of the radiator off, start your engine. The radiator cap should be changed, in case the rubber seal is too rough or dry. Read more on radiator leak repair.

The radiator flush and fill cost can also vary as per the locations - some mechanics in major cities may charge you more than the others. The radiator repair cost can be around USD 100.
