OK, so let's open up this discussion again........cause I am just as curious.
Does this mean I would be foolish to try adding baffels to the side tanks
of my existing raditator to direct flow so the water goes through the
radiator two to three times instead of one pass??
Why then, does my car still heat up using a non-standard 160 degree
thermostat?? In effect don't the holes drilled in say, a 195 degree
thermostat effectively open it up earlier as would a lower rated thermostat?
Would not the drilled holes possibly lead to INCREASED cavitation and
therefore, air, in the system??? Is not air in the system a killer to the
cooling capability??
Par usual, I am now more confused than ever. I suppose the best place to
start out is to have my current radiator rodded-out and boiled, start
tinkering and measure the results....what we all normally do.....

Allan
