Likewise...interested to learn outcomes, findings with suction 'workaround' method.
Assuming regular rad PM practice, seems limited % of old satisfactory condition coolant 'leftover' may not be detrimental to carryover unlike residual engine oil/changes...?
Use/experience [~2yrs, 6Kmls] - Regarding do88 rad, no quality issues to-date. Performs as advertised including several SoCal triple digit ambient temps, occasional autocross, along with super hot days in canyons and stop-n-go traffic. With recent install of CanChecked gauge display, now capable of monitoring actual coolant temps, patterns this summer.
BTW - Same favorable performance indicated with do88 oil, PS coolers [all coolers installed simultaneously]. Nominal oil temp ~220F in most conditions and quickly 'cools' under challenging engine loading. Never observed temps exceeding ~230F.
