The Cummins Automatic High Idle is a feature that engages on its own when the temperatures are below freezing. This feature is known to be present in Cummins engines for a long time.
It is important to note that idling, even on high idle, can cause excessive wear on internal components and can shorten the life of the engine. Therefore, it is not recommended to use high idle unless necessary, as it can increase maintenance costs.
The Cummins Automatic High Idle is a feature that many Cummins engine users are familiar with. This feature engages on its own when the temperatures drop below freezing, providing a high idle speed for the engine. However, it is important to understand that idling, even on high idle, can have negative impacts on the engine’s longevity and increase maintenance costs. We will explore the topic of Cummins Automatic High Idle and discuss its pros and cons. We will also provide insights on when and how to use high idle effectively without causing unnecessary wear and tear on your Cummins engine.
What Is 6.7 Cummins Automatic High Idle?
6.7 Cummins Automatic High Idle: The 6.7 Cummins Automatic High Idle is a feature that allows the engine to operate at a higher idle speed when certain conditions are met. This feature is designed to provide benefits such as quicker warm-up times and improved performance in cold weather conditions. When the temperatures are below freezing, the automatic high idle feature engages on its own without any user intervention. It is important to note that idling, even on high idle, can cause twice the amount of wear on internal components compared to normal operation. This can lead to increased maintenance costs and potentially shorten the life of the diesel engine. Therefore, it is recommended to use high idle mode only when necessary and avoid prolonged idling.
Benefits of using the high idle mode:
- Quicker warm-up times
- Improved performance in cold weather
- Reduced idling time
- Potential fuel savings
- Extended lifespan of engine components
How To Enable 6.7 Cummins Automatic High Idle
Enabling high idle mode on your 6.7 Cummins can be done by following a step-by-step guide. Before enabling this feature, there are a few factors to consider. First, it’s important to understand that idling, even on high idle, can cause excessive wear on internal components, leading to higher maintenance costs and a shorter engine life. However, if you still want to enable high idle mode, here’s how you can do it.
1. Start by pushing the ‘SET’ button on your Cummins truck. This will activate the high idle mode.
2. Another option is to use the cruise control feature. Set the cruise control at the desired RPM to engage high idle.
3. There are aftermarket kits available that allow you to install a switch specifically for high idle.
4. Some Cummins models have an automatic high idle feature that engages when temperatures drop below freezing.
Remember, enabling high idle mode should be done with caution and only when necessary. It is important to prioritize the longevity and health of your diesel engine.
