1986 Chevrolet K15 problems
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2002 model years, this is the final generation of the C/K model line. In a branding change, GMC adopted the GMC Sierra nameplate for all its full-size pickup trucks, leaving the C/K nomenclature exclusive to Chevrolet.
Internally codenamed the GMT400 platform, GM did not give the model line a word moniker (e.g., "Rounded-Line series" for its predecessor). After its production, the model line would informally become known by the public as the "OBS" (Old Body Style), in reference to its GMT800 successor. In starting a different tradition, the model line overlapped production with both its predecessor and successor; the model line again shared body commonality with GM medium-duty commercial trucks.
Over nearly a 14-year production run, the fourth-generation C/K was assembled by GM in multiple facilities in the United States, Canada, and Mexico. After the 2000 model year, the fourth-generation C/K was discontinued and was replaced by the GMT800 platform (introduced for 1999); the C3500HD heavy-duty chassis cab model remained in production through 2002. In line with the GMC Sierra, Chevrolet subsequently adopted a singular Chevrolet Silverado nameplate for its full-size truck line (which remains in use).

Common 1986 Chevrolet K15 problems
The Chevrolet K15 1986 is a reliable vehicle, but like any other car, it has its common problems based on complaints from owners. One of the most frequently reported issues is related to the distributor and spark plug wires. The HEI distributor and spark plug wires are prone to failure, causing problems with the ignition system and leading to starting issues.
Another common problem is related to the fuel tank, specifically the sidesaddle design, which was reported to be the worst auto crash fire defect in the history of the U.S. Department of Transportation. The sidesaddle design, installed in over 10 million trucks, was found to be a significant safety issue, with the potential for fuel leaks and fires in the event of a crash. A good solution to this problem is to convert from a sidesaddle tank to a rear-mounted Classic Performance Products tank or a fuel cell.
The 1986 Chevrolet K15 also had some functional changes, such as the relocation of the fuel tank to the driver's side, the use of low-drag fan clutches, more efficient radiators, radial tires, disc brakes with lower drag, revised rear springs with a lighter, semi-floating axle, new automatic-transmission clutches, quieter exhaust systems, and a lighter battery. While these changes were intended to improve the performance and efficiency of the vehicle, they may have contributed to some of the common problems reported by owners.
Engine choices were also limited in the 1986 model year, with the 305-cubic-inch V-8 with electronic spark control being the only available option for 49 states, while the 400-cube V-8 was removed from availability. This limited the options for owners looking to upgrade or replace their engines.
In summary, the Chevrolet K15 1986 has several common problems, including issues with the distributor and spark plug wires, fuel tank design, and limited engine choices. While these issues can be frustrating for owners, they can often be addressed with proper maintenance and repairs.
