FST Oil Cooler

[Wingnut]

I have been looking at these coolers and I can't figure out how the oil gets pumped through them. I see where the oil comes out of the bottom end and goes through the cooler and then back into the head. What I don't understand is how does the oil get pumped out of the bottom end? It has been a while since I have had the clutch cover off and I just can't picture how it works. Can anyone help me with that?

Also, has any one that has one noticed the engine running cooler or the oil lasting longer?

I have one and it works great. The way they work is with your stock oil pump. You tap a hole in your side case right where your oil pump, pumps oil and once your tapped into it, it will feed the oil through your new oil lines, through the radiator, and then straight on your head.
