Should You Rev Your Engine When Jumping a Car?

When your car battery dies, you may be tempted to rev the engine of the car that is jump-starting yours. However, this is not recommended. Here are a few reasons why:

It Can Damage Your Car’s Engine

Revving the engine of the car that is jump-starting your car can put extra stress on the engine and cause it to overheat. This can lead to serious damage to the engine, including blown head gaskets, warped pistons, and cracked cylinder heads.

It Can Damage Your Car’s Electrical System

Revving the engine of the car that is jump-starting your car can also damage the car’s electrical system. This can lead to blown fuses, fried wiring, and even a fire.

It Can Be Dangerous

Revving the engine of the car that is jump-starting your car can be dangerous. If the jumper cables are not properly connected, the high voltage from the car’s battery can cause an electrical shock.

It’s Not Necessary

In most cases, it is not necessary to rev the engine of the car that is jump-starting your car. The alternator of the car that is providing the jump-start will be able to provide enough power to start your car without revving the engine.

What Should You Do Instead?

Instead of revving the engine of the car that is jump-starting your car, you should follow these steps:

1. Make sure that the jumper cables are properly connected.
2. Start the car that is providing the jump-start.
3. Wait a few minutes for the battery in your car to charge up.
4. Start your car.

If you follow these steps, you can safely jump-start your car without revving the engine.

Conclusion

Revving the engine of the car that is jump-starting your car is not recommended. It can damage your car’s engine, electrical system, and be dangerous. Instead, follow the steps outlined above to safely jump-start your car.
