How do I flush my own radiator?

it's a 96 nissan sentra..4cylinder

Answer 1

Go to Auto Zone or other automotive parts store. You can do it with just the Radiator flush bottle or you can buy the radiator flush kit.

The flush kits are all the same more or less just a matter of price. All you need to put one one is a knife and a phillips screw driver, and a flat tip screw driver. But check the heater hose that you will attach it too. If it has cracks, has a bubble in it, or is hard where it attaches to the heater or engine I would get another one. If you do, you find out what size you need. Now it is cheaper to buy the hose in one , I think 6 foot, coiled inside a rubber bag, then seperatly. Ask the guys at the parts store and they can help you. The kit has the directions on how to flush your radiator. I prefer this as you have a hose pressure flushing everything out.

But the regular way, is to go and buy a bottle of radiator flush. Follow instructions. Basically, drain all the water out. Put the flush in fill with water, run the engine, then drain, fill with water.

What the kit does is drain any flush you may have in the engine. You see when you drain from the radiator you do not drain the water in the engine block. Also with the kit attached to the hose. Then when you decide to change antifreeze again, you can flush the engine out with regular water, and do a thorough job. This way you will not have the reside dirty water with water deposits antifreeze in the engine.

I have a 98 Chrysler van which I plan to keep FOREVER. So the second year, I bought the flush kit and attached it. Now every year, I use the regular radiator flush. I want to maximize keeping the radiator core free of water deposits. Then about every three or four years I use the heavy duty flush. Those water lime deposits is usually what makes a radiator go bad first.

Answer 2

There is an attachment that connects the the radiator drain to back flush the radiator. It should only cost a few dollars at an auto supply store.

The way I usually do it is to remove the cap and start the car and let it warm up. This will open the valve in the hose. Now open the valve at the bottom of the radiator and while water is draining keep filling it at the top until the water is clear. Turn off engine, drain completely, and refill.

Answer 3

Very carefully. Get some radiator flush from the auto parts store and follow the directions. There is usually a drain valve in the bottom of the radiator. The real problem is disposing of the drained coolant. You can't just leave a puddle or let it run down a storm drain. It's illegal and dangerous. Antifreeze is VERY toxic. It has a sweet smell and taste, so animals and kids will drink it.
