Before you put it back together, I'd do a little cleaning with a stiff brush and soapy water in case you need to investigate further later. That way, any new leaks will be readily apparent.
I will! ... Once I get things back together on the weekend...Assuming you are using the 50/50 coolant mix, you won’t get much steam leaking out. Try placing some paper-towel “diapers” around suspected leak locations to see if they pick up any pink coolant while running at NOP/NOT/NOL (Normal Operating Pressure, Temp, Level).
