The first thing to do is to enter "warmth" and "thickness" in the search dialog. Either way it works perfectly. I use water and wetter water and with a 180* thermostat and I never go above 190* in a turbocharged street car. I've had heat issues with the stock radiator before (210 and slow freeway climb until the heater kicks in) and that's absolutely a thing of the past for me. Definitely eliminates the need for a redirect on a standard or mid-range Miat.
