I have just changed the coolant in my D3 from the orange colour to the genuine Volvo green coolant.
I am a little concerned as I have heard a few stories of if you mix orange and green coolant it goes to jelly and clogs everything up.
I drained the coolant from the radiator drain and only got about 4 litres out. I refilled with de-inonised water and did three hot flushes (run to temp and drain) each time got lighter and lighter before refilling with genuine Volvo coolant.
Have I done enough flushes or will I encounter problems later down the line due to changing coolant colour?
