I am intstalling my new cooler from Hardin Marine 620-700 Thermostatically controlled oil cooler and I need to know what side the hot oil from the motor goes into. The side with the thermostat or the other?

It didn't come with destructions or Hardin didnt know?

No destructions, I can't get a hold of hardin tech and I'm rigging it tonight, I was hoping somebody could tell me how they have theirs rigged.

The hot oil goes into the Thermostat side.

Thanks for your help !!
