Does Revving the Engine Help Heat the Car?
Introduction
In the cold winter months, many people wonder if revving the engine will help heat up their car faster. The answer to this
question is a resounding no. In fact, revving the engine can actually do more harm than good.
How Does a Car’s Heating System Work?
A car’s heating system works by circulating hot water through the heater core, which is located in the dashboard. The heater
core is made up of a series of small tubes that are filled with hot water. As the water circulates through the tubes, it
transfers its heat to the air inside the car. The heated air is then blown into the passenger compartment through the vents.
Why Revving the Engine Doesn’t Help Heat the Car
Revving the engine does not help heat the car because it does not increase the flow of hot water through the heater core. In
fact, revving the engine can actually reduce the flow of hot water through the heater core because it increases the engine
speed. When the engine speed is increased, the water pump that circulates the hot water through the heater core has to work
harder to keep up. This can result in a decrease in the flow of hot water through the heater core, which in turn will result
in a decrease in the amount of heat that is transferred to the air inside the car.
What Does Help Heat the Car
There are a few things that you can do to help heat up your car more quickly:
- Turn on the heater fan. The heater fan will help to circulate the warm air inside the car.
- Open the vents. Opening the vents will allow the warm air to flow into the passenger compartment.
- Drive the car. Driving the car will help to warm up the engine, which will in turn warm up the heater core.
Conclusion
Revving the engine does not help heat up your car. In fact, it can actually do more harm than good. If you want to heat up
your car more quickly, turn on the heater fan, open the vents, and drive the car.
