The 1990 Chevrolet S-10 Blazer is a compact sport utility vehicle (SUV) that marked a significant era in Chevrolet's truck and SUV lineup. Released in the late 1980s, the S-10 Blazer was the successor to the Chevrolet Blazer, a popular and rugged SUV that had been in production since 1969. However, the 1990 S-10 Blazer brought a new level of refinement and technology to the segment, offering a more modern and capable driving experience. This generation of the S-10 Blazer was built on the GM GMT400 platform, shared with other popular compact trucks and SUVs like the Chevrolet S-10 pickup truck and the GMC Sonoma. It featured a unibody construction for increased rigidity and a smoother ride, a departure from the body-on-frame construction of its predecessors. The S-10 Blazer offered a choice of two engine options: a 2.5-liter inline-four engine producing 115 horsepower, or a 2.8-liter V6 engine boasting 130 horsepower. Both engines were mated to either a five-speed manual or a four-speed automatic transmission.

The 1990 Chevrolet S-10 Blazer was a popular choice among consumers seeking a versatile and affordable SUV. Its compact size made it easy to maneuver in urban environments, while its four-wheel-drive capability ensured off-road prowess. The interior provided ample space for passengers and cargo, with a comfortable and functional design. The S-10 Blazer also offered a range of amenities, including power windows, power locks, air conditioning, and an AM/FM cassette stereo. However, as is the case with any vehicle, the 1990 S-10 Blazer required regular maintenance and repair to keep it running smoothly and reliably. This is where a service and repair manual comes in. A well-detailed manual provides the necessary information for owners and mechanics alike to perform routine maintenance tasks, diagnose and troubleshoot issues, and understand the inner workings of the vehicle. Featuring comprehensive instructions, diagrams, and specifications, the manual acts as an invaluable resource for keeping the 1990 S-10 Blazer in top condition.
