Up front, let me say I've begun planning for my next winter projects. Let me also say I'm amazed by so much of the work of many on this forum, and I'm hoping those that have been there and done that can shed light on my apparent confusion..
Before we go further, I've looked at the cooling layout of the '18 XPT a fair bit, and I'm relatively impressed (with respect to the 2016 turbo's guys pain!). Still, guys smarter and more experience than I have performed mods I don't quite get, so I'm hoping ya'll can show me what the heck I don't get.
1) I don't appreciate the HCT "remove the thermostat and block the bypass" idea. In fact, for those that don't know, the XPT thermostat is dual acting, fully dynamic, and capable of completely shutting off the bypass on it's own. Why would I replace something that well thought out? Does it not work as advertised?
For those that don't get the coolant bypass thermostat, read this:
And:
Now I know some pretty smart guys here are using this, so I'm awaiting their correction of what I've missed. (and assuming I'm about to learn something too).
2) I don't understand the split tank concept either. Sure, the coolant recovery tank is shared, but that doesn't "appear" to be mixing the two systems coolants in operation in any way. In fact, the stock tank doesn't seem to be in the normal operating flow path of either system. (unless I'm reading the coolant flow diagram of the service manual wrong, for I don't see supply side, only a return. Just like any overflow tank would have for refill during cool-down)
Is the coolant somehow intermingling between system #1 and the aux cooling system #2 during operation (which would suck, and will have to be corrected) and I'm not seeing it?
If not, what then is the value of the split tank idea?

Thanks in advance!
