how do you drain a car's water?

Answer 1

on the underside of the radiator you will find what looks like a screw. This is called the petcock, once you remove that the water will drain freely. if you can not find it, or if your car dosnt have one, you can always remove the lower radiator hose. the only problem with doing that is that they like to kinda melt them selves in place from the heat, so if you decide to take that route, stop by your local auto parts store and get a replacement hose, if yours dosnt tear or get stuck, you can always return it for the 1.50-4.00, depending on how long of a hose you need, that you just spent. If doing this you will have to either also remove the upper radiator hose, or remove the radiator cap so that the air pressure will force the coolant out of the system. the only other thing is that with all of the work that you will be doing being on the underside of the radiator, if you have to raise the vehicle to access it, you will of course have to lower the vehicle again for it all to drain out, unless you use a lift. also, remember to do any and all work when the car is cold. if you do any running around before attempting to drain the car, you more then likely will be experiencing second degree burns. I recommend waiting about 2 to 2.5 hrs before draining to allow your car enough time to cool down so that you don't get burned. if you have any wiring running any where near the area that you will be working in, which is very rare but i have seen it, it will be best to remove the positive battery cable in order to prevent any shocks, because we all know that water and electricity don't mix well at all, especially when you include a human body.
Good luck and be careful.

Answer 2

Look at the bottom of the radiator and find a valve called a petcock. These usually turn opposite from regular threads as I recall. You might think about going to an auto parts store and buying a flush kit. Prestone makes them. Anyway, you cut one of the heater hoses and insert a "T" fitting and connect a garden hose to it and turn the water on. Watch until the water comes out clear. You can also buy a bottle of radiator flush chemicals, and put that in too. Follow the directions on the bottle. With all the fluids drained, then premix the coolant and distilled water at a 50/50 ratio and pour it back in the radiator.

good luck,

Oh, while I think about it, you may also get a small bottle of water pump lubricant that you add to the coolant.

Answer 3

There is a little valve on the bottm of the radiator called a ''petcock'' turn it to drain the water out but be sure you drain it into a clean pan in case you are going to reuse it. You will probably get a gallon or gallon and a half of liquid depending on the capacity. you can check the owners manual to be sure.You wont be able to get every drop of water out this way but most of it because there is water in the lower radiator hose that will need to be disconnected also and the engine block cooling jackets that wont come out unless you get a flush kit from the auto parts store. Just make sure the engine has cooled off and the radiator cap is removed before attempting to do this procedure and it wont hurt to wear goggles also.

Answer 4

Your car shouldn't really have water in it except for your widow washer, you probably mean your coolant,
There is a usually a drain valve at the bottom of your radiator.

Answer 5

take the top and bottom hose off the radiator, water will come out of the bottom hose entry forced out by air pressure from the top
