Thermostat operation does wierd things if they are blocked. Looped and the tstat and cooling system operates normally. If they are blocked then the tstat sits in a "cold" spot of static water which causes late opening of the thermostat at low speeds with excessive heating and then excessive cooling at higher speeds. This is with a factory stat at least.
This is why the factory setup has water flowing between them at all times with a bypass type heater control valve.

As long as water flows through it, it doesnt care. Maybe you can find a molded u turn hose that will fit.

I'm running mine with a heater control valve which effectively blocks it. No problems. In modern cars, there is always flow through it though. Also marine versions loop the inlet/outlet, so I do believe it works better with flow through it all the time.
If you search the conversions forum, there's a part number for a loop hose.
