1985 Chevrolet S15 problems
The Chevrolet S-10 is a compact pickup truck produced by Chevrolet. It was the first domestically-built compact pickup of the big three American automakers. When it was first introduced as a "quarter-ton pickup" in 1981 for the 1982 model year, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version of the latter was released in 1991, called "Syclone." The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. These models are sometimes internally referred to as the S/T series to denote two and four wheel drive models respectively (similar to the full size Chevrolet C/K trucks) despite all versions being badged with 'S' nomenclature.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
The S-Series ended production in Brazil in 2012, being replaced by the Chevrolet Colorado, but still with the name S-10.

Common 1985 Chevrolet S15 problems
The 1985 Chevrolet S15, also known as the GMC S15, is a reliable vehicle, but like any other car, it can have its share of problems. Here are some of the most common issues reported by owners:
- Drivetrain Problems: The drivetrain of the 1985 Chevrolet S15 is a complex system that transfers power from the engine to the wheels. It includes the driveshafts, axles, joints, differentials, and wheels. Common drivetrain problems include resistance when turning, heavy vibrations in the floorboards, clunks when shifting, and vibration as the vehicle accelerates. These issues can be caused by worn-out CV joints, CV axles, or driveshafts.
- Engine Performance Problems: Some owners have reported a loss of power in their 1985 Chevrolet S15. This can be caused by various factors, including faulty spark plugs, ignition wires, distributors, or rotors. In some cases, the problem can be due to a misfire, which can be caused by a faulty ignition module or a dirty carburetor.
- 4x4 Engagement Problems: The 1985 Chevrolet S15 has a 4x4 system that can sometimes fail to engage the front differential. This can be caused by a faulty vacuum switch or a malfunctioning front drive actuator. When this happens, the front wheels will not receive power, and the vehicle will not be able to engage 4x4 mode.
- Locked Front Differential: Some owners have reported that their front differential is locked, causing the vehicle to bind when turning on concrete. This can be caused by a faulty front differential or a problem with the front axle engagement system. A locked front differential can cause the vehicle to become stuck or to have difficulty turning.
- Transmission Problems: The transmission is a critical component of the drivetrain system, and it can sometimes experience problems. These can include difficulty shifting, slipping gears, or a malfunctioning shift indicator light. Transmission problems can be caused by various factors, including low transmission fluid levels, worn-out clutch components, or faulty sensors.
To maintain the drivetrain system in a 1985 Chevrolet S15, it is essential to follow the manufacturer's recommendations for lubricating bearings and gears and checking and changing differential fluids. Regular maintenance can help minimize repairs over time and ensure the overall power and performance of the vehicle. If you notice any problems with your 1985 Chevrolet S15, it is essential to address them promptly to prevent further damage and avoid unsafe driving conditions.
