Done with the throttle body heater, time to bypass. Parts list?

The primary path for coolant to leave the intake is the outlet pipe, which has an inside diameter of ~1 inch (#8 in the attached illustration).
Next largest is the heater inlet pipe (#4). Its inside diameter is ~½ inch.
Those two outlets allow for all the coolant flow out of the intake that's needed. The nylon line from the TBH to the expansion tank has a I.D. of 5mm (#7). If the cooling system in a DII needs that third, tiny outlet from the intake to keep temps in an acceptable range there are much bigger problems.
And cooling system pressurization is managed via the expansion tank cap,
Make sense?

Sorry, those were just my thoughts, as mistaken as they may be. And I apologize if my ability to be tactful is on the fritz today, my bad, I honestly meant no harm...

All done. Feels great to get that out of there. One less leak to worry about.
I opted to just run a new hose from the intake manifold to the tank and removed the TBH ports and hoses altogether. I don't think there's a problem doing either method discussed here, for me I just preferred the aesthetic and simplicity of a single return hose. ¯\_(ツ)_/¯
You can see the bow. Stupid design.

If you look at the coolant flow diagram, you'll see that the ONLY thing in that circuit is the TBH. There's no reason to connect the two lines together.

Also, I wouldn't delete the TBH, instead I'd use this. Have it on my 3rd Disco and ... brilliant, no issues.
