I would stick with the oem coolant itself. Water doesn't have the same rated life as a higher content chemical coolant. Guys who pour straight distilled water have better cooling than antifreeze, but you need to change it out every year or two to prevent corrosion. Mind you this only applies if you in an area that doesn't freeze. A little might be okay, but I eventually you have to make sure the ratios stay correct.
