Should You Rev Your Engine When Jumping Another Car?

The Answer is No

When you’re jumping another car, the goal is to transfer power from your battery to the dead battery in the other car. Revving your engine will not help with this process and could actually damage your car.

Here’s Why Revving Your Engine Doesn’t Help

When you rev your engine, you’re increasing the speed at which the alternator spins. This can lead to a power surge, which can damage the alternator or other electrical components in your car. Additionally, revving your engine can cause the battery to overheat, which can shorten its lifespan.

What You Should Do Instead

Instead of revving your engine, you should follow these steps when jumping another car:

1. Park your car close to the other car, but don’t let the bumpers touch.
2. Turn off the engines in both cars.
3. Connect the jumper cables to the batteries in the correct order (positive to positive, negative to negative).
4. Start your car and let it run for a few minutes to charge the other car’s battery.
5. Start the other car and remove the jumper cables.

Conclusion

Revving your engine when jumping another car is not only unhelpful, but it can also be dangerous. By following the steps above, you can safely and effectively jumpstart another car.
