Because the makeup bottle is always vented to atmosphere, you are liable to catch a whiff of coolant every now and then during the radiator cap pressure bypass condition. This is precisely when you DO NOT want to open the cap to investigate. The vent opening is clearly visible on the upper left of the photo I posted above.
Other places to check are all hose connections, the radiator tank to core solder areas - AND - the water pump seal weep hole below the shaft. It is virtually impossible to actually see this, but the telltale is coolant trails down the lower pump inlet hose, or pooling on top of the oil filter, which is where mine was collecting.
