1) prevent corrosion in which different metals are used
2) kill any algae or anything other nasties that might be growing in the water
Lately some people have just been using distilled water + 10 or so drops of iodine (make sure it's not the kind that has alcohol in it)
This question comes up so many times.
1. Antifreeze is not all the same. The person i quoted from is correct. It doesnt serve any cooling benifits. Think about it, It would say SUPERCOOLANT and not ANTIFREEZE if it cooled better. The principles in cars is to prevent the engine from freezing over and to keep your radiator free from rust and algae.
2. The pumps on cars are built differently from pumps like D5 or the liang DDC. These pumps are highly sensitive to phosphates so you need to use a phosphate free antifreeze. Only a few company even offers this, one is zerex, but not regular zerex, its a high performance zerex used on race cars and other exotic cars. PEPBoys and Autozone will not carry this line as its too rediculously expensive. The only local place to obtain a phosphate free antifreeze would a porsche dealer.
3. DI water alone is fine, and will cool the beset, BUT, be prepared to see green hair crap growing in your tubes and possibly even cloging your radiator. IM TALKING ABOUT ALGAE! the thing is worse then a infestation of cockaroachs. They can grow in almost anything and even in your coolant if you dont periodically flush your system every 6-8 months. RESPECT THE ALGAE! they been around since the dawn of time and they will most likely out live our entire species.
