will water cool as well as antifreeze?

will antifreeze keep the motor as cool as antifreeze?

Straight water will cool better than anti-freeze.

x2 on pure distilled water ... most racing organizations will not allow antifreeze . It makes things real exciting if you hit a patch of it on the track . Try running distilled water and water wetter with the water pump lube in it .
Makes it a lot easier to clean up if you have to change a hose of spring a leak .

Except it has no rust preventative and water pump lubricant additives as found in antifreeze.

Actually a 50/50 mix of distrilled water and antifreeze with some water wetter will cool much better than straight water or distilled water...

That's what Water Wetter is for. I run distilled water with Water Wetter.

Not exactly true. Pure water carries and transfers heat energy better than a 50/50 mix. But the mix has a higher boiling point under pressure, and a lower freezing point.

The heat rejection factor of water being 1.0 pure antifreeze has a .8 heat rejection factor . Any addition of antifreeze to water porportionately reduces the mix's heat rejection capabilities. Pump lubrication, rust inhibitors, elevated boiling points and lowered freezing points are the only advantages of a glycol/water mix.

Well hopefully the freezing weather is over here in Oregon for the time being. It better be, I just dumped the antifreeze solution I've been running through the winter and changed out to water and wetter for the summer.

I can actually SEE the difference in temperatures running water vs antifreeze mix. Water alone is better.

The only advantages? If you can you should run 50/50 all year long.

Why?

I run about a 25% AF + a surfactent year round. Seems to do OK. In cooler temps I have to put duct tape on the radiater to get the temps up to 180*.

The only time I use anti-freeze is if the car will be exposed to freezing temps. Since my car is never exposed to freezing temps; maximum cooling, pump lube, and corrosion protection are achieved with water and Prestone Super Anti-Rust. There are other corrosion inhibitors that will do the same thing as Prestone. I won't comment on WW and other surfactants except to say that if it makes you feel good knowing it's in there, then pour a bottle in... the odds are that your water pump seal will be just fine...

Same here. Never put any anti freeze in. Just distilled water and a bottle of water wetter. And it gets near the Arizona temperatures around here in the summer. Like 118° with a heat factor of 124/128.

I live in North Alabama. Our weather ranges from mid 20's to 100 degrees. I drive year round with 25% AF and 75% distilled water. I don't when it gets below 45.

I have my fan set to come on at 205 degrees. I run fuel injected so my operating temp is 195.

over 27,000 miles

my big block buddies run 25/75 and water wetter.

Dwight

[PANAVIA]

Agreed , distilled or highly filtered water with some AF and WW.
75% water,22% AF, 3% ww.

Feel blessed in oregon for the good water, Tap water in California --isn't .

Plus modern green antifreeze is scary ! It just doesn't taste the same as in the 1980's.

My car runs much cooler with less than without AF. I had to dump my AF for track day and since that time the Cobra has never come close to over heating. My only concern is engine block corrosion etc. I use WW and am investigating quality anti-corrosion additives. Any feedback on quallity corrosion inhibiters is appreciated.

if your car is exposed to freezing temps. and you dont want to drain your rad. every year then run a mix that will keep your coolant from turning to ice.....and yes it will crack your block....if your not around freezing temps. then run distilled water and water wetter and a good corosion inhibitor like super anti-rust....
80% water 15% ww and 5% anti rust that should keep your cooling system operating at its best along with a coolant recovery tank.
