Anti freeze
I have some old anti freeze ( Peak ) that has been sitting around for a few years. I know that it sits on shelves for some time, but how long is it good for if it hasn't been opened and has not been used.
Thanks :confused:

How much is a Gallon? $7.00? Buy some fresh stuff for the Vette and use the old stuff for the DD. And don't forget the 2 bottles of "water wetter" and only 25% of anti-freeze (at the most). :thumbs:

Re: Anti freeze (LOTAHP)
I agree with you new is probably the safest way you say 25% antifreeze. What kind of water do you use to stop mineral buildup? I always heard that Peak antifreeze was the best. I aslo heard was to mix it with some of the old antifreeze that you are changing: :rolleyes:

Re: Anti freeze (NHvette)
Distilled water is what I was thinking also, thru the years of changing this stuff what mixture would you recomend. First thread said 25% antifreeze and 75% distilled water. I guess Ill just chuck the old anti freeze and by new :cheers:

Havoline sez that due to silicate instability (traditional antifreeze), shelf life is about 18 months. Silicate free antifreeze (extended life antifreeze) that the shelf life is 8 yrs. :crazy: Charles

Re: Anti freeze (Mako72)
I don't have an answer to your question, but Tom Dewitt recommended a 50-50 mix. Antifreeze has some additives that are helpful for the cooling system. It is anti corisive and I think it keeps the water pump lubrcated. Plus it doesn't freeze.
But anti-freeze doesn't cool as well as water so that is why he recommended the 50-50 mix.
He also suggested I buy the stuff that is pre-mixed. For the simple reason that I can know for sure I got the mix right, and if I ever need to add any more it will maintain the mix ratio. Premixed costs a little more, saves a lot of trouble.
