@rwest I have been using an Fluke IR thermometer to test in various places. It should be pretty hot when exiting the engine before flowing through the thermostat. But the cooled (90F) oil coming through the other side of the loop is likely equalizing the temp at aux. thermostat and never allowing it to open.
