Chevrolet S-10 Blazer Common Problems
The Chevrolet S-10 Blazer is a midsize sport utility vehicle (SUV) from General Motors that was manufactured in 1983 all through 2005. Playboy magazine awarded the S-10 Truck of the Year for 1995. But even with this great honor, it is undeniable that the S-10 Blazer had been known to have some problems. Here are some of them.
The early years of the S-10 model were focused on creating competition for Asian small trucks. Its lineup of engines included a heavy, iron cast 2.5-liter four-cylinder; a diesel motor; and a 2.8 V-6 engine from the car divisions of General Motors. All were woefully underpowered, with the V-6 notorious for being unreliable as a truck motor. The V-6 suffered from heat-related head failure, computer-controlled carburetor issues, and low torque. The 2.8-liter motor was replaced with the 4.3-liter, which proved a more robust power plant that was ideally suited for low-torque truck applications, evolving until it was the only engine choice for the Jimmy (the Chevy Blazer's twin) and Blazer S-10 variants. This V-6 had its problems, including a design flaw that caused \"loping\" at idle. The 2.2-liter four-cylinder was the replacement for the 2.5 \"iron duke\" motor.
The Blazer jerks from first to second gear; it's worse on wet days because it will jerk harder on that upshift. Also, Blazers have had problems with the computers that make its fuel gauge meter work.
The S-10 brake system was originally a front-disc, rear-drum setup, which changed for the 1998 model to four-wheel discs. The addition of anti-lock braking systems as standard equipment in 1992 made the S-10's brakes more complex. Recalls for the newly developed ABS plagued the braking systems for the S-10 line. Problems with the rear parking brake that was incorporated into the disc brake design were common. The hydraulic master cylinder design had not changed much during the production.
On first-generation models, interior dash and panel materials were of higher quality and secured with sturdier mounts; the second generation's loose, plastic panels often squeaked and rattled, unlike the previous model's construction techniques. These changes were spurred by a need for lower manufacturing costs and a new dashboard platform for General Motors' Chevrolet S-10 Blazer parts.
Heating and air conditioning
The vehicle was charged with R-12 refrigerant which isn't manufactured anymore-there are still some stocks around that are a part of the remaining Chevrolet S-1- Blazer accessories, but they are very expensive ($25 to $50 per pound, 2 to 5 pounds per vehicle).
