I am running the oil through one side of this heat exchanger and coolant through the other side. So far so good, the oil temp is staying within a couple of degrees of coolant temp and there are no leaks, so I am very pleased. The other thing I like about this heat exchanger is that it came with the ports covered to keep debris out during shipping. I flushed the heat exchanger out with acetone before I installed it to ensure that there was no debris or metal particles in it, and it was perfectly clean.
