What engine does a 2005 Chevy Colorado have?
The 2005 Chevrolet Colorado offered several engine choices depending on trim and market: a 2.8-liter inline-4 gas engine, a 3.5-liter inline-5 gas engine, and a 2.8-liter Duramax turbo-diesel option.
In detail, the Colorado’s 2005 lineup was built to balance everyday driving needs with work capability.

Availability varied by trim, region, and transmission choice.
Engine options for the 2005 Colorado
Below are the engine configurations GM offered for the 2005 Colorado, with approximate output. Actual figures can vary by model year, trim, and equipment.
- 2.8-liter inline-4 gasoline engine — around 175 horsepower and about 185 lb-ft of torque. Typically paired with a 5-speed manual or 4-speed automatic transmission.

Regional and trim variations
Diesel availability was not universal and depended on the market and the chosen trim level. In some regions and configurations, the Duramax diesel was offered primarily on certain cab/bed layouts and with specific transmission and drivetrain combinations. Always verify the exact engine on a given used Colorado via the VIN or a window sticker.
