The job of your Sentra’s thermostat is to regulate the temperature of the engine.

This allows the coolant to continuously enter the engine.

What does it mean when your car heater is not working?

There are two hoses coming to and from the heater core. They both should feel warm or hot to the touch with the engine on. If one of the hoses is hot, and the other one is cold, that is a pretty good indication that the heater core is clogged. If the neither hose has any heat, you may have air in the cooling system, low fluid, or low pressure.
