Yes, the torque specs are 15 ft-lb, here is the diagram directly from the Titan A60 Field Service Manual. I modified/added a couple of the images to help a little.
This is the thermostat housing. Make sure the rubber O-ring covers slides over the thermostat itself. The gasket has a slit around the entire inner diameter to ensure proper fitment. Also, make note of the orientation of the ''Jiggle valve" when re-installing thermostat. The jiggle valve allows trapped air to exit, since the trapped air will rise to surface, so to speak.
Just little tid bits I thought i'd share. Hope this helps you further.
