What Year Did Afm Start On 53

Active Fuel Management (AFM) is a technology introduced by General Motors (GM) that allows for improved fuel efficiency by deactivating specific cylinders in an engine during light loads. Many people wonder when AFM was first implemented in GM vehicles, especially in the popular Chevy Silverado and GMC Sierra trucks.

History of AFM

AFM was first introduced by GM in the year 2005. It was a significant step towards enhancing fuel economy without compromising the power and performance of the engine. AFM enabled the engine to operate on fewer cylinders when full power was not required, resulting in reduced fuel consumption and emissions.

AFM in Chevy Vehicles

In the Chevy Silverado and GMC Sierra trucks, AFM was introduced in the year 2007. This technology allowed the engine to transition between 8 and 4 cylinders, depending on the driving conditions. It aimed to optimize fuel efficiency while maintaining the capability to deliver full power when necessary.

Potential Issues with AFM

While AFM provided several benefits, there were some reported problems associated with it. Some Chevy Silverado and GMC Sierra owners experienced issues like ticking noises and excessive oil consumption due to faulty AFM lifters. These problems were more prevalent in certain model years and required attention and potential repairs.

Should I Avoid AFM?

The decision to avoid AFM depends on personal preference and priorities. Although AFM was designed to improve fuel efficiency, some users may prefer the traditional operation of all cylinders to avoid potential issues or concerns. It is recommended to research and consult with experts to make an informed decision based on individual needs.

When AFM Motor Fails

AFM motor failure may occur at various mileage points, depending on multiple factors such as maintenance, driving habits, and vehicle conditions. Some Chevy Silverado and GMC Sierra owners reported AFM motor failures around 100,000 miles or more. Regular maintenance and proper care can help prolong the lifespan of the AFM system.

Summary

AFM was introduced by GM in the year 2005, and in the Chevy Silverado and GMC Sierra trucks in 2007. While AFM provides fuel efficiency benefits, it is essential to be aware of potential issues with AFM lifters and motor failures. Deciding whether to use AFM or not depends on personal preferences and priorities. Regular maintenance and care can help mitigate potential problems and ensure the longevity of the AFM system.
