The 'fix' I tried (and plan to try again) was to use the

wet wing fuel tanks as radiators (almost zero weight gain ).  This of

requires that the fuel itself be used as the heat transfer medium

This sounds like the turbine engine fuel/oil heat exchanger. A smallish
unit mounted alongside the turbine that contains the subject exchanger,
which preheats the kerosine and cools the oil.
