Thanks for the detailed pictures and description Greg, you're definitely a pioneer in terms of finding alternatives to the v6 oil cooler. As a material scientist, I can see why they would use aluminum in the oil in terms of cooling capacity. Its odd that Saab engineers didn't think about the basic properties of aluminum, in that it has a much higher rate of crack propagation compared to steel, especially when under continuous heat cycles. I imagine the oil cooler in our v6's going through thousands of heat cycles, eventually leading to the cracks and leaks that we see on the board. If the caddy oil cooler had the radiator "fins" the saab cooler has, I would not hesitate to use it. The many fins the saab cooler has increases its surface area, increasing efficiency by at least a factor of 2. What we as consumers do not know though, is the actual temperature difference of the oil in our turbocharged engines compared to the NA cadillac engine. I do remember Swedecar mentioning the v6 runs cooler than the 4. It would be interesting if this oil cooler is one of the reasons our engines don't have sludge!
