whatever temp the engine is is the temperature that should b blowing from ur vents the thermostat is designed to warm ur engine quickly and maintain its temp for fuel efficiency and driver comfort. if there is no hot air in ur car and the engine is overheating sounds like the water pump isnt pumping or there is a HUGE air pocket in your cooling system. your thermostat being stuck closed WOULD overheat your car but also cook you out with the heat on...
