On my flying installation the "to
throttlebody" goes to bottle (surge can). "To heater" is tapped
for temp sensor probe (made so long it sticks into water flow).
I removed the entire thermostat assembly and replaced with the
attached. Two bottom tubes are 3/4" return hoses from radiators.
Top is 5/8" hose to left rad. Drilled out the stock sensor hole
for 5/8" fitting for hose to right rad. Small hole is for 1/8 NPT
temp sensor. No thermostat. 35 psi cap on top of bottle. Simple
but would have been simpler with just one rad.

Planning my coolant flow for my engine setup on test stand

list/rx-8 forums I couldn’t find any reason I cannot just block
the in and out spots for the throttle body and heater cores.
Will be bypassing the thermostat with center plug and hole
tapped for air bubble. Only other line will be from radiator
to expansion tank.
Am I mis understanding something?
