how do u flush a radiator? is it something u can do at home or does it need a professional and why do flush it

Answer 1

You can do it yourself, it's not hard. You need to go to a auto parts store and buy a flush and fill kit. Follow the instructions so you don't cut the wrong hose when installing the "T" in the line. After you have everything all hooked up, place a pan under the radiator and drain off as much coolant as you can. When the flow stops, start the car and let it run, but not for more than a minute or two. This should purge most of the remaining coolant from the engine.

Close the valve on the bottom of the radiator, fill with clean water. Start the engine again and watch the water level in the radiator. When it drops that means the thermostat has opened. At this point add the bottle of Super Flush, top off the radiator with water, replace the cap and turn the heater to HOT and HIGH.
Let the engine idle for about 15 mins, or go for a short drive.
Allow the engine to cool, then remove the radiator cap, insert the deflector tube, (from the flush and fill kit) and connect your garden hose to the "T", when the discharge coming from the "T" is just clear water, you're done.

Hope that helps

Flushing is easy. It's a good idea to do it to get rid of any dirt and mineral deposits in the radiator and cololing system.
It helps water pump and thermostat last long and helps to prevent corrosion in radiator.
You can do it at home pretty easily with enough time and the right equipment.
Go to autozone, napa, pep boys, or another local auto parts store. Get a bottle of radiator flush, a gallon of ani freeze (not the 50/50 mix), if you don't have a jack or ramps get one or the other of those. you'll also need 2 5 gallon plastic buckets and some cat litter, and an adjustable wrench.

Step 1. Jack up vehicle or put it up on ramps. Ramps are safer.
Step 2. When engine cools down. Carefully open radiator cap.
Step 3. Take empty 5 gallon bucket and place under lower radiator drain plug.
Step 4. Use wrench to loosen drain plug until fluid drains out.
Step 5 . Wait a couple of hours.
Step 6. Tighten plug. Remove bucket.
Step 7 Add radiator flush and water to radiator. Put on cap.
Step 8. Start engine. Let idle for 30 minutes.
Step 9. Turn off engine. Let it cool down.
Step 10. Empty bucket.
Step 11. Repeat steps 2 - 6.
Step 12 Fill radiator with just water.
Step 13. Repeat step 8.
Step 14. Repeat steps 9 - 11.
Step 15. Fill radiator with the gallon of antifreeze and water.
Step 16. Put on radiator cap.
Step. 17. Close hood.
Step. 18. Casrefully back car off ramps or remove jack.
Step 19. Done. Go get a beer and relax.

Answer 5

It is something you can do at home, but you will have to purchase a kit to do it that sometimes is more expensive than taking it somewhere. You can usually find someone to do it for around 50 dollars. It is done very rarely so I wouldn't invest the money because you'll only save a little bit. You have to flush it because debris collects in the fluid and impedes the performance of the cooling system, and if bad enough can damage it.

Answer 6

I used to flush my system every year and install new antifreeze. I now just drain and refill as flushing (if done improperly) can damage the system. If you do decide to flush make sure you buy the kit and use the rubber bladder they include. The bladder reduce the pressure so water pressure will not damage your cooling system. City water pressure can be in the hundreds of pounds much higher than a cars water pump and can cause damage. It also pushes water through in the reverse direction to back flush the system.

By just draining and refilling I avoid the possibility of damage. I always drain and refill with distilled water and antifreeze mix 50/50 (distilled water removes all minerals so the water will not damage aluminum or brass) and I do this every two years.

Answer 7

You can do it yourself but you should capture the old coolant and have it recycled...may be illegal in some states to not do this. Best to have it done professionally with a power flushing system that injects air pressure in the flush cycle to loosen any crud in the passages and inspection of the cooling system components like radiator, belts, metal lines for corrosion, hoses,air dam, fans, etc..to spot any problems before they go bad. Should be done every couple of years to keep the system in good order...anti-corrosion additives and lubricants in coolant do degrade over time
