The Chevrolet Blazer: A Comprehensive Guide

The Chevrolet Blazer nameplate has a rich and varied history, gracing everything from rugged, body-on-frame SUVs to modern, car-based crossovers. Understanding its evolution is key to making an informed buying decision. Originally a trim package on the Chevy C/K pickup, the Blazer transformed into a standalone SUV in 1969. Over the years, it’s transitioned from a capable off-roader to a family-friendly daily driver. Today, the Blazer competes in the mid-size crossover SUV segment, offering style, technology, and practicality.

Generations of the Chevrolet Blazer

First Generation (1969-1991): The K5 Blazer

The first generation Blazer, known as the K5 Blazer (and the GMC Jimmy), was a full-size, two-door SUV built on the short-wheelbase Chevrolet C/K truck platform. It was designed to compete with the Ford Bronco and International Harvester Scout.

  • 1969-1972: Solid front axle, removable top, inline-six and small-block V8 engine options.
  • 1973-1991: Significant redesign with a more modern look, improved interior, and available full-time four-wheel drive. Turbo-Hydramatic transmissions became standard. The removable top remained a key feature. Engine options expanded to include larger displacement V8s. This generation saw gradual updates, but the core design remained consistent.

Second Generation (1983-2005): S-10 Blazer

The S-10 Blazer was a smaller, more fuel-efficient version based on the Chevy S-10 pickup truck. It came in two-door and four-door configurations.

  • 1983-1994: Introduced as a compact SUV with independent front suspension, initially with inline-four and V6 engines. Four-door models arrived in 1991.
  • 1995-2005: Significant redesign with updated styling, improved interior, and enhanced safety features like airbags. A Vortec V6 engine became the standard and offered improved performance. The two-door model was discontinued in 2001, with the four-door soldiering on until 2005. During this period, the Blazer gained a reputation for being a good value, but also for some reliability issues.

Third Generation (2019-Present): The Modern Crossover

The Blazer nameplate was revived as a mid-size crossover SUV, sharing little mechanically with its predecessors. This Blazer prioritizes on-road comfort, technology, and style.

  • 2019-Present: A sporty, modern design inspired by the Camaro. Available with four-cylinder and V6 engines, and front-wheel or all-wheel drive. Features a modern infotainment system, advanced safety features, and a comfortable interior. Styling updates and technology enhancements have occurred throughout this generation.

Buying Advice

K5 Blazer (1969-1991)

If you're looking for a K5 Blazer, prioritize rust-free examples. Expect to spend time and money on maintenance and repairs. Early models (1969-1972) are highly sought after, commanding a premium. Thoroughly inspect the frame, body panels, and undercarriage for rust. Check the engine and transmission for leaks and unusual noises. Budget for potential restoration work.

S-10 Blazer (1983-2005)

Look for well-maintained examples with documented service history. Avoid models with excessive rust or known engine issues. Have a mechanic inspect the 4.3L Vortec V6 for intake manifold gasket leaks. Test the four-wheel drive system thoroughly. Consider a newer model (1995-2005) for improved safety features and styling.

Modern Blazer (2019-Present)

Consider your budget and desired features. Test drive different engine options to see which suits your needs. Check for any outstanding recalls or technical service bulletins. Read owner reviews and compare the Blazer to other mid-size crossovers before making a decision. Opting for a Certified Pre-Owned (CPO) model can provide additional peace of mind.
