Cooling question - airflow - design

correct.

after water flows through top hose, top tank, cores, bottom tank, then the return hose going to pump, and if water is still too hot or climbing, probably because of my 1/4 mile runs @ 7 minutes @ 3Mph, it'll trip the fan.

Seemed simple enough to me. Not having the bypass hose or a cabinet heater core circuit makes the water flow much more direct.

Now, finding a drop-in 33 inch hose.
