You have heard of the thermostat right? You do understand how that works yeah? It stays closed until the coolant reaches the temp to open. That means EGR or not the engine will get to the same temperature and maintain it. At best the missing EGR heat load may slow the warm up cycle but once it’s there the engine will keep it there. Engines are designed with an efficient temperature in mind to provide best fuel efficiency and wear control.
