Does the engine have to be on for the heat to work?
Yes, you can turn on the heat in a car without gas in the tank, meaning the engine would obviously not be running. However, turning on the heater in this scenario would not have the desired effect. The heat in most vehicles operates by using a heater core connected to the cooling system.
Why won’t my car heat up when idling?
Low coolant is number one for good reason, it’s the most common root cause of heater problems. Proper coolant fluid level is important, as low coolant creates a void inside the system and the void creates air pockets. More on this later.
How does the heating system work in a car?
It might sound a little funny, but your vehicle’s heating system is a part of its cooling system. The cooling system circulates a coolant through the engine that absorbs heat. That heated coolant then runs through the radiator, where the heat dissipates.
How does a heater work in a truck?
As you drive your truck, the engine gets warm. This heats the coolant, and the cooling system has to circulate it through the radiator to bring the temperature back down. When you turn on your heater, the coolant flows through the heater core inside your dashboard. This allows the hot air to blow through your vents and heat up your cabin.
