The most important bleeder is the 1 on the Radiator ~ you need to be
getting BubbleFreeFluid coming out of there before you close it & then
you should get fluid coming out of ThermostatBleeder before you close
it ~ it is not actually essential to use the ThermostatBleeder but it
can help ~ so if it is stuck & it doesn't want to open don't force it
& break it.
