I have just replaced the rad on the mini as its a bit bent and was loosing coolant.
Once replaced and rebuilt I have opened the bleed screws and pressure cap prior to refilling. I have begun filled the equilising tank to the max marker with new coolant but it only took a cup full to achive this. I was expecting it to take around 5ltr then start appearing at the bleed screws when i run the engine.
What am i doing wrong?
