No it it cools the oil in the engine think of it as a oil filled radiator submerged in coolant.The oil flows thru it and thru its fins and being submerged in coolant cools the oil in the engine.

Ok thank you I was just trying to avoid pulling the intake to replace the oil cooler, I did bypass it but now it's acting like its starving the top end with oil. I pluged the supply and return lines to the cooler so maybe it's not getting any oil circulation .
