Has anyone actually had a pressure gauge hooked up to the cooling system in the following conditions:
Idling when cold
Idling at operating temperature
at 2500 rpm with fan blowing air through rad to simulate highway cruising
I'd be curious to see all the pressure readings under these conditions.
And another thing that hasn't been clarified, is the 2 bars of pressure gauge or atmospheric? I assume it's gauge since that's how we measure everything else (tires, fuel pressure, etc.).
