I looked around the net to find out what the temperature range is for water wetter. I am specifically looking for it low temperature. If it is mixed just with water and water wetter what is the lowest temperature is will protect the coolant from freezing? I live in the Denver Colorado area and need to know if I need to swap out the water wetter for full coolant / anti-freeze. I know not to use automotive coolant. It can cause issues in the engine over time.
Anybody have any ideas?
