How to do a radiator flush on a car?

A radiator flush on a car helps to remove any build-up of debris or deposits that may have accumulated over time. It’s a simple process that only takes a few minutes, and it’s a good idea to do it at least once a year to keep your car’s cooling system running efficiently. Here’s how to do a radiator flush on a car:


1. Drive the car around for at least 15 minutes to allow the engine to reach its operating temperature. This will help to loosen any debris that may be stuck in the radiator.

2. Place a large bucket underneath the drain valve, which is usually located at the bottom of the radiator.

3. Open the drain valve and allow the coolant to drain into the bucket.

4. Close the drain valve once the coolant has finished draining.

5. Remove the radiator cap and fill the radiator with a 50/50 mixture of water and antifreeze.

6. Replace the radiator cap and start the car. Allow the car to idle for a few minutes, then turn it off.

7. Check the coolant level in the radiator and add more if necessary.

while it might be tempting to add water to your engine coolant in order to thin it out, this is actually not a good idea.

Other factors that can affect the interval at which you need a coolant flush include the type of coolant and the environment in which you typically drive.
