I was inspecting my bike and was looking at the oil tank and cooler set up....

I can't seem to figure out or understand how the set up works.... since both the in and out lines for the oil cooler are located at the top of the tank, how does oil flow through the cooler? what pressurizes the oil to flow through the cooler?

I am just curious because I think my oil is getting too hot and I want to make sure that the cooler is working properly....

Thanks for looking and you input...

 

I've had dozens of oil tanks apart cleaning them either for new hydrostatic pump or for motor job and I've never taken a picture of the oil lines machined into the aluminum tank ..

Here's a picture of the oil flow I tried to change the arrows color red for hot oil and blue for cold oil ..

Here is a poor picture of the inside of the oil tank ..
