Does low coolant level in radiator affect the heat output in winter?
Yes. The heater core provides the heat which blows out your vents. The heater core has engine coolant flowing through it (it is like a mini radiator) which creates the heat which warms the air that comes out your vents. If you have low coolant, there may be no coolant circulating through heater core, thus causing cold air to blow out vents.
