The O Ring goes against the flange of the engine and the flat of the oil cooler goes next to the gasket on the filter. If you are adding the take off for a remote filter then the gasket there would go against the flat of the oil cooler. Is that how you are setting it up? Or did I read it wrong.
The picture shows it upside down as opposed to how it will be on the engine. The coolant flow direction doesn't matter.
The one I have on my car has no problem running the coolant in one side or the other. I tried to bring hoses in towards the hose take offs the best I could to prevent kinking once they get warm. I didn't get it quite right on the first try and had to adjust the cooler by loosing it up and twisting it a few degrees. Then re-tightened.
I was planning on removing the stock oil cooler as I am installing a remote filter and cooler with a fan. I changed my mind and have installed a new stock cooler to make sure the oil temps come up quickly.
