One odd thing after my drive today. I attempted to release the air from the radiator petcock, and nothing came out. I mean not air, or radiator fluid, nothing came out. Until...I relieved the pressure by removing the cap from the Surge tank. Then radiator fluid came shooting out of the petcock.

It seemed odd to me, as I thought the whole system would be under pressure and opening the petcock would release the pressure?? Confusing. I guess i'm on the suction side of the pump and under negative pressure at the point of the petcock.
