Does Running the Car AC Make the Engine Hotter?
The Answer: Yes
Running the car AC does make the engine hotter. This is because the AC compressor is driven by the engine’s crankshaft, which means that it takes power away from the engine. This can cause the engine to run hotter, especially if it is already under a lot of stress, such as when driving in hot weather or towing a heavy load.
How Much Hotter?
The amount that the engine heats up when the AC is running depends on a number of factors, including the outside temperature, the speed of the car, and the condition of the AC system. However, as a general rule of thumb, the engine will run about 10-15 degrees Fahrenheit hotter when the AC is on.
Is This a Problem?
In most cases, running the AC will not cause the engine to overheat. However, if the engine is already running hot, or if the AC system is not working properly, running the AC could cause the engine to overheat. If you are concerned about your engine overheating, you can have it checked by a mechanic.
Tips for Minimizing the Heat Buildup
There are a few things you can do to minimize the amount of heat that is generated when running the AC:
- Avoid running the AC at high speeds.
- Park in the shade whenever possible.
- Use a sunshade to keep the interior of the car cooler.
- Have the AC system serviced regularly.
Conclusion
Running the car AC does make the engine hotter, but in most cases, this is not a problem. However, if you are concerned about your engine overheating, you can take steps to minimize the heat buildup.
