We won't know for sure till someone gets it on a a lift and videos it.
I too have no idea about 'liquid cooling'. The temp sensor is total BS band aid. Just tells you if the tcase fluid gets too hot. I mean that's nice, but the fluid needs to be changed. The link on the parts website...
Good news! Answering my own question. Presumably this is the same PTU in the escapes which when looking at the parts diagram from the thread below, certainly seems to have a drain and fill plug. 7A10A and 7A10B...
I am well aware of how snow tires work...none of this matters if the vehicle ramps up on snowpack and gets high centered...
I have seen 4 runners and lifted grand cherokees with snow tires and mud terrains get high centered. Having a badlands doesn't change that much like some people here...
This was an issue with the 3g escape and many other ford vehicles where there was no scheduled fluid intervals for the ptu. Luckily on the 3g escape you could get to the fill plug at least and suck out and refill fluid with a transfer pump.
Any word on serviceability of the 4g escape/BS PTU...
You can get high centered with perfect tires and much more clearance...It depends on the snow. Some circumstances, driving a low vehicle (or with a low front air dam plowing the snow) will get further than a high vehicle with a nice smooth, skid plated undercarriage...
High centering in snow...
