Just wondering if you mix the antifreeze in a bucket to do the 50/50 mix or if you put on container of antifreeze in the rad and then 1 of water and so on? does it matter?

 

i pour it in seperately, i use a small plastic bottle fill with antifreeze then one of water, keeps me 50/50 on the mix.

 

I usually mix it before.

I have an empty, 1 gal. windshield washer bottle that I marked at 1/8, 1/4, 1/2 and the top. I fill it up to one of the lines with water, then up the next one accordingly with antifreeze.

Like if I only want a quart of mixture, then I fill it to the 1/8 mark w/ water, then to 1/4 w/ antifeeze, etc. That's two 1/8 amounts of each, or correctly speaking, one 16oz. amount of each to make 32oz.

Then I just poor it in, not having to worry about it being the right mixture or not. Plus there's usually a little left over for topping it off after it cycles through hot-cold a few times.

I guess I've done it so many times, I got tired of trying to eyeball it while pouring it into the radiator. ( <----- One eye missing)

IMHO it doesn't matter.

With a new engine or a drain & flush or something I put in however much AF I'm going to use (usually 1 gallon, then anything else like Water Wetter or block sealer or whatever, then fill it the rest of the way with water. I get it as full as I can. Then I fill up the tank to a little past the "Full Hot" mark with water.

That gives about a 70/30 mix, and within a couple of heat/cool cycles even the overlflow tank has the AF mix in it.

When I add, I add water most of the time, then if it looks weak, I add AF. My cooling systems don't leak though so I rarely add anything after a fill.

 

I keep an empty antifreeze bottle and pour 1/2 of my new bottle into that, then fill them both the rest of the way with water. That way, I can keep a bottle of ready mix in the trunk.

 

Just remember that if you have flushed the engine with straight water, the block is still holding probably 1 gallon of the stuff. So if you pour in a 50/50 mix it will actually be a gallon weaker.



Assuming of course you just drained the radiator and not the block. New engine probably better to mix first.
