Manual: No warm up

[MikeHTally]

I believe the thermostat only prevents the coolant from going through the radiator, keeping it in the engine itself. But part of that circuit goes through the heater core, there isn't a 2nd thermostat that bypasses the heater core.

Correct. The 'stat blocks (or seriously reduces) the coolant going to the radiator.
