Flushing out a car radiator isn't that technical and you don't need to be a rocket scientist or race car maker to know how. All you need is a little guidance.
Here's how to flush a radiator. First of all you need to know what a radiator is. A radiator is a device that cools the entire engine from overheating. A good radiator should be clean and free from debris to that it cools effectively.
A car radiator eliminates the buildup of heat that comes from the hot water that circulates within the cooling system of the engine. When hot water enters the top part of the radiator, it then filters down to the cooling fins or core fins and cools it before returning it back into the engine.
As per good maintenance, the radiator of the car should be flushed every five to six months. This prevents any particle build up and lowers the rust that gets built up inside.
Steps in flushing a radiator:
1. You must park your car over a level surface. Then you must turn on the heater. While engine is heating up, cover the engine to prevent splashes from going into the radiator.
2. Remove the radiator cap. Let water out and detach upper and lower hose radiators.
3. Check the hoses. Faulty hoses should be replaced.
4. Allow fluids to leak out of radiator and note the color. Brown water means radiator has a rust build up.
5. Plug a running hose into the radiator and let water run for several minutes until the water that drips is clear and not dirty.
6. Plug the bottom part of radiator with the same running hose to do a reverse flush action. Repeat flushing from top and bottom for several times.
7. When done, fill the radiator with coolant liquid and close the radiator cap.
8. Make sure that the cap is in good condition or else replace it.
9. Start the engine and leave running for several minutes to see if there is any leak.
10. If there is no leak, then procedure was successful. You may need to add a sealant on the cap to ensure that no coolant escapes but it is not that important and can be added later on.
When learning the process of flushing a radiator, you may need assistance of a mechanic to help but for immediate flushing, you should be able to do it yourself. And that is how you successfully flush a radiator.
