Ok after the HCI swap, I have been smelling coolant. The coolant level has been the since the swap was done about a month and a half ago. The oil looks good. When the swap was done, I put in a new FRPP radiator. Is this normal to smell the coolant with this radiator? I don't think it would be but nothing seems to be wrong with the cooling system and the car doesn't over heat (well according to the stock temp gauge).
