Does Heater in Car Cool Down Engine?

Introduction

The heater in your car is not designed to cool down the engine. In fact, it can actually make the engine run hotter if it is used excessively. This is because the heater core is a small radiator that is located in the passenger compartment of the car. When the heater is turned on, hot coolant from the engine flows through the heater core and heats up the air in the passenger compartment. This can make the engine run hotter because the coolant that is flowing through the heater core is not being cooled down as effectively as it would be if it were flowing through the radiator.

How the Heater Works

The heater in your car works by using a small radiator called a heater core. The heater core is located in the passenger compartment of the car and is connected to the engine’s cooling system. When the heater is turned on, hot coolant from the engine flows through the heater core and heats up the air in the passenger compartment. This warmed air is then blown into the passenger compartment by the heater fan.

Why the Heater Can Make the Engine Run Hotter

As mentioned above, the heater core is a small radiator. This means that it does not have as much surface area as the radiator that is located in the engine compartment. As a result, the heater core is not able to cool down the coolant as effectively as the radiator. This can cause the engine to run hotter if the heater is used excessively.

When to Use the Heater

The heater should only be used when necessary to keep the passenger compartment warm. If the heater is used excessively, it can cause the engine to run hotter and can also lead to other problems, such as a blown head gasket.

Conclusion

The heater in your car is not designed to cool down the engine. In fact, it can actually make the engine run hotter if it is used excessively. The heater should only be used when necessary to keep the passenger compartment warm.
