This is a dangerous move....
The concentration of corrosion inhibitors will be too low to protect the
metal from the glycol, which is still corrosive even at low concentrations.
Most good antifrezes will, on the label, stress 'do not use in less than 33%
strength'. this is not just to sell more product.
In summer ( and winter if your local climate allows) you could use no anti
freeze at all and just go with some corrosion inhibitor and the water
wetter.
Incidently, the water wetter could be replaced by a few drops of dishwashing
detergent (sink not machine) as this is pretty much all that it is: a mild
surfactant that lowers surface tension and increases the the waters ability
to 'wet' the metal, thus increasing heat transfer.
