The 5.3L GM engine with a DOD (Displacement on Demand) or AFM (Active Fuel Management) system is widely used across various General Motors vehicles. When considering a DOD Delete for a 5.3L GM engine from 2014 to 2022, it’s crucial to know which vehicle models are compatible with this engine type. Here’s a list of vehicle fitments for the 2014-2022 5.3L GM DOD Delete engine:
Chevrolet Silverado 1500 (2014-2022): A popular full-size truck often equipped with the 5.3L V8, ideal for those seeking a balance between power and fuel efficiency.
GMC Sierra 1500 (2014-2022): Similar to the Silverado, the Sierra 1500 with a 5.3L engine is a common candidate for a DOD Delete, offering enhanced reliability and performance.
Chevrolet Tahoe (2015-2022): A full-size SUV known for its spacious interior and towing capacity. The 5.3L engine in the Tahoe is often used for family and utility purposes.
GMC Yukon (2015-2022): The Yukon, especially the Denali trim with a 5.3L engine, is another full-size SUV that benefits from a DOD Delete, enhancing its performance and reliability.
Chevrolet Suburban (2015-2022): Given its size and use for passenger and cargo transport, the Suburban with a 5.3L engine is a prime candidate for a DOD Delete, ensuring smooth operation under various load conditions.
Cadillac Escalade (2015-2022): While the Escalade is often associated with the larger 6.2L engine, some versions come with a 5.3L engine. Owners looking for consistent performance might opt for a DOD Delete.
Chevrolet Avalanche (2014-2013): Note that the Avalanche was discontinued after the 2013 model year, but those with a 5.3L engine from the last production years might still consider a DOD Delete for enhanced performance and reliability.
A DOD (Displacement on Demand), also known as Active Fuel Management (AFM) in General Motors’ vehicles, is a technology designed to improve fuel efficiency and reduce emissions by deactivating a portion of the engine’s cylinders under certain driving conditions, typically during light load situations. However, some vehicle owners and technicians prefer to delete or disable this feature for various reasons. This process is referred to as a DOD Delete or AFM Delete. Here’s a comprehensive overview:
What is a DOD Delete?
Components Involved in a DOD Delete:
Common Reasons for DOD Delete:
Increased Reliability: Earlier models with DOD/AFM were particularly prone to issues such as lifter failures or excessive oil consumption. Removing the system can lead to a more reliable engine lifespan.
Consistent Performance: Drivers can enjoy the consistent power and torque of a full V8 engine without the transition between different modes, which can sometimes be felt as slight hesitation or roughness.
Oil Consumption: Some DOD/AFM-equipped engines are known to consume more oil, especially when the system is engaging and disengaging. A DOD Delete can mitigate this issue.
Sound: Enthusiasts often prefer the sound of a full V8 engine over one with active cylinder deactivation.
Customization and Control: A DOD Delete gives more control back to the driver and mechanic, allowing for more traditional diagnostics and tuning.
