I know that engine coolant is a fluid in the engine used to dissipate heat spots and keep the engine cool in general as the moving parts generate heat. In this context, I would call the oil an "engine coolant".
I also found out what happens when a cars engine doesn't have enough oildoesn't have enough oil in it, which results in overheating among other things. But there is also a radiator in most cars to keep the engine coolant cool. However, due to the fact that oil is too viscous at cold and engine temperature to pass quickly through the thin pipes leading to the radiator to be cooled down by a massive fan. This is where another type of engine coolant comes in - a water based substance.
How does the cooling system work (i.e. how is heat passed from oil to water or air)?
Is there one pump for the entire cooling system (explain?) or two separate pumps (i.e. one loop for oil, one for water based substance) or more?
What exactly is supposedly referred to when someone says "engine coolant"? Oil? The water based substance? Air?
They are all fluids and they all serve the same purpose after all (I think).
