Rev Engine When Jumping Car

Introduction

When you’re trying to jumpstart a car, it’s important to rev the engine of the running car to help send a surge of power to the dead battery. This can help to start the dead car and get you back on the road. However, it’s important to rev the engine at the right time and for the right amount of time. If you rev the engine too much or for too long, you could damage the engine or the alternator.

When to Rev the Engine

The best time to rev the engine is when the dead car’s starter motor is engaged. This is when you hear the starter motor making a grinding noise. Once the starter motor is engaged, rev the engine to about 2,000 RPM. Hold the engine at this speed for 10-15 seconds, or until the dead car starts.

How Much to Rev the Engine

When you’re revving the engine, it’s important to do so gently. Don’t slam the gas pedal all the way down. This could cause the engine to race and damage the alternator. Instead, slowly increase the engine speed until you reach 2,000 RPM. Once you reach 2,000 RPM, hold the engine at that speed for 10-15 seconds.

What to Do If the Dead Car Doesn’t Start

If the dead car doesn’t start after 10-15 seconds of revving the engine, there may be another problem. It could be that the battery is too dead to start the car, or that there is a problem with the starter motor or the alternator. If the dead car doesn’t start, you may need to call for a tow truck.

Conclusion

Revving the engine of the running car can help to jumpstart a dead car. However, it’s important to rev the engine at the right time and for the right amount of time. If you rev the engine too much or for too long, you could damage the engine or the alternator. If the dead car doesn’t start after 10-15 seconds of revving the engine, you may need to call for a tow truck.
