Well, we have finally finished the instillation of a new RV-10 oil cooler on our Lycoming IO-360-A3B6D, and it is being fed by a 4" SCAT tube running from the baffling behind the number 4 cylinder. On start up and taxi the other night we saw a continued climb in oil temps from 100 all the way to 230 after about 10 minutes of runnnig on the ground
Obviously, something is wrong, so we checked the oil cooler to make sure there were no air bubbles in the cooler, and then pulled the vernatherm for a boil test.
What we saw was that the element would not move until the water temperatue hit 180 degrees (two different thermometers were used), and by 195 it opened its full value. The element ended up moving a total of around 1/4".
Does anyone know what temp those things are supposed to open? It has 85C stamped on the top...is that when it begins to open or is that when it should be fully open? Also, how far is that element supposed to move? I'm guessing that it's a defective part, but before I go drop another $250 I just wanted to make sure.
Thanks guys!
