Some new facts I learned and then I'm off to pick up another AC unit for the house (DAM it's hot)!!
Evans expands about 7%, thus the loss of water if zero pressure and no overflow tank, or overfilling the system to begin with.
Evans contains NO additives to prevent corrosion, because it's non-corrosive. Adding water won't hurt in a pinch, other than boiling point trouble (remove/loosen the cap in an emergency) but the water could cause corrosion trouble in time. Flush and replace the coolant after the emergency situation. Slow leak and trying to get home? Loosen cap, go to zero pressure, add water as required! Is this stuff great or what????
