That is probably not coolant, the rubber decomposes, I scrape silicone
sealant with a razor blade(put tape over anode cavity to keep silicone out),
clean with acetone.I use the anode cup from an RCA fly kit where I did not
use the lead. The RCA cup fits perfectly. Also check the shield around
anode cup, usually has a hole burned in it, hth.
