Chevrolet TrailBlazer: generations, engines and what to check when buying
The Chevrolet TrailBlazer is a mid-size SUV that was introduced in 2001. In Lithuania, you'll most commonly find the GMT360 generation (2002–2009), imported from the USA. Later, other completely different models were sold under this name. We'll look at the engines, trims, and what to check.
TrailBlazer in brief
The TrailBlazer (GMT360) replaced the Blazer and quickly became a popular family SUV: spacious interior, rear or all-wheel drive, and smooth, comfortable ride. It was offered in a shorter version and a longer EXT, featuring a third row of seats.
Later, the TrailBlazer name appeared on SUVs in Southeast Asia and South America, and since 2021, on a small front-wheel-drive crossover. This article is mainly about the first (GMT360) generation.
Which trim to choose
The main choice is between the shorter TrailBlazer or the longer EXT and the engine. The EXT is better for larger families, while the shorter one is easier to park.
TrailBlazer SS (2006–2009) – the sporty version with a V8 and upgraded suspension. It's a rare, dynamic car, but it's more expensive and guzzles fuel.
Engines and transmissions
The most commonly fitted engine is the 4.2-litre inline-six (around 275hp) with a four-speed automatic gearbox. In later years, a 5.3-litre V8 was also offered.
The SS version comes with a 6.0-litre V8 (around 395hp). Drive is to the rear or all four wheels (4WD) with a selectable low-range transfer case.
What to check when buying a used TrailBlazer
This car's electronics and small components can wear out over time: check the instrument cluster, climate control settings, and other electrical functions. The engine is usually reliable but requires meticulous maintenance.
Test the automatic transmission – it shouldn't hesitate or slip. Check the full drivetrain while driving, and inspect the suspension components for wear.
Inspect the frame and body for rust, and check the accident history via the VIN (if the car is from the USA).
