Okay. Quick question.
Coolant or water. The car I bought has been running on water for 2 years (from the looks of it)...
Summers are approaching. Should I get the radiator flushed and cleaned ? and then use coolant ?
Or is there really not much difference.
That and how much will it cost (time and money) approximately?
Also: What coolant should I use, and should I mix water with it ?
