RX7 oil cooler in/out lines?
 

i purchased a used rx7 cooler and lines and was wondering 1) how the thermostat worked (does it still allow flow just not through the cooler) because my case has the gene berg pump/ cover and is plugged for full flow cooling and filtering
2) And which line was the inlet and which is the outlet? There is one on top of the tank and one on the side of the tank
