Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.

The heater is dependent on the coolant flowing through the heater core. If the coolant is low then there will not be any heat.
What can cause a heater to stop blowing heat?
well you could just turn the heater off heater blower ---- If it is a car heater then check your coolant level. the heater is driven off a heat converter that is fed by the radiator system. When the coolant fails to pump round the radiator system the car internal heater doesn't work. Driving without coolant in the system will result in the engine overheating and seizing.

Why doesn't the heater work in 2003 Buick Regal?
Low coolant? Heater core airbound, restricted, or plugged? Bad thermostat? Water pump not circulating coolant?
What would cause the heater in a 1998 Chrysler Concord to blow cool air?
Check the coolant level...if the level is too low, it will not flow through the heater core. Next, check the thermostat. If it is sticking, it will not let the coolant heat up. These are inexpensive, and easy to change by the owner. If none of these work, have the heater core checked by a mechanic. An obstruction in the core, or the heater hoses, will keep coolant from flowing through the core, thus not heating the air.
Why does my 2003 dodge stratus heat work but when i stop at a light it shoots out cold air?
Check your radiator coolant level. On some cars, low coolant will let air bubbles into the heater core which can result in intermitant cold air bursts.
