Chevrolet Colorado (2012-2022): How to Remove the Bumpers

Production Years and Generations

The second generation of the Chevrolet Colorado (conventionally referred to as Mk2) was produced from 2012 to 2022. However, there are important nuances:

  • For the US and Canada, production began in 2012, and the model underwent a facelift in 2015. In 2022, it was replaced by the third generation.
  • For markets in South America and Asia (e.g., Thailand), the second-generation Colorado debuted as early as 2011 and was produced in some countries until 2023.

This pickup was developed as a global model, so it had different names:

  • Chevrolet Colorado – the primary name in North and South America, as well as Australia.
  • Holden Colorado – in Australia and New Zealand (under the Holden brand until 2020).
  • Chevrolet S10 Max – in some Latin American countries (Brazil, Argentina).

The Colorado Mk2 is a midsize pickup that replaced the outdated first generation (2004–2012). It was offered in several configurations:

  • Regular Cab – a rare work-oriented version.
  • Crew Cab – the most popular option with four doors.
  • Extended Cab – 2+2 doors with reduced rear space.

Dimensions varied depending on the modification:

  • Length: from 5126 mm (short wheelbase) to 5713 mm (long wheelbase).
  • Payload capacity: up to 650–750 kg, depending on the engine.
  • Ground clearance: 210–255 mm (higher in the Z71 version).

Gasoline engines:

  • 2.5L (4-cylinder) – 200 HP, 253 N·m (base option).
  • 3.6L V6 – 308 HP, 373 N·m (top option for the US).

Diesel engines (for international markets):

Transmissions:

  • 6-speed manual (base).
