Weird thing in the MotoRad 206-180 Box

Mine went in with a new Felpro gasket. Very thin layer of RTV applied on the gasket and the bolt threads. Torqued the housing to about 28 ft-lbs (FSM is 30 ft-lbs but 28 felt right). I let the gasket sit out with RTV about an hour before installing and let the installed unit sit about 18 hours before filling and starting the car. No leaks so far and the car is warming to temp a lot more swiftly.
