Chevrolet TrailBlazer II (2012–2022): How to Remove the Bumpers.

The Chevrolet TrailBlazer II is the second generation of a midsize SUV, introduced in 2012 and produced in some countries until 2022. This model was based on the GMT-31XX platform, which was also used for the Chevrolet Colorado and GMC Canyon. The TrailBlazer II stood out as a practical and reliable SUV with a powerful engine and a body-on-frame construction, making it popular in regions where off-road capability and durability were essential. In different countries, the model was sold under various names depending on the market and specifications. Here are some of the most well-known names:

• Holden TrailBlazer — in Australia and New Zealand.

• Chevrolet Colorado 7 — in some Asian countries, such as Thailand and the Philippines.

• Isuzu MU-X — in some countries where Isuzu markets the model based on the same platform (e.g., in India, South Africa, and other regions).

• Set of socket wrenches with a ratchet or power drill.
