Engine coolant is used, but not to warm the incoming air, it is to adjust idle speed under different conditions, one of which is engine temperature as the link explains.

They work the same on both B and D Series. I know as I have a B20 Delsol and a D16z6 EG Sedan.

If you live in a Warm climate then it might be unneeded. However in Colder Climate's Such as the Northern US States or Most of England and Scotland. Then you will want it. It will help the car idle when its cold.

you mean no coolant going through the TB, but it must run to the IACV.. that's the coolant bypass is what it's called..
