1991 Gmc K2500 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 1991 Gmc K2500 problems
The GMC K2500, produced in 1991, is known for several common problems that owners have reported. This article will explore these issues in detail, providing valuable information for those who own or are considering purchasing this vehicle.
- Windshield Wiper Motor Component Failure: Models produced between 1990 and 1999 may experience intermittent windshield wiper failure due to a defective wiper motor control board. This issue can be temporarily resolved by lightly tapping on the control box, but a more permanent solution requires replacing the wiper motor control board.
- Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: This issue is common in older Sierras and Silverados, including the GMC K2500 1991. Coolant or oil leaks from intake manifold gaskets can cause the engine to run roughly or stall, and may or may not trigger the check engine light. Overhauling or replacing the internal distributor is necessary to correct this problem.
- Steering Wheel Position Sensor Failure: This problem can cause a service stability message to appear in the Silverado or Sierra. The failed sensor may cause intermittent or regular errors, such as every time the truck is started or the wheel is turned. Replacing the sensor should fix this issue.
- Excessive Oil Consumption: This is a common problem in 2007-2013 GMC and Chevy trucks, but it can also affect the GMC K2500 1991. Excessive oil consumption can be caused by various factors, such as worn piston rings or valve guides, and may require significant engine work to resolve.
In conclusion, the GMC K2500 1991 has several common problems that owners should be aware of. These issues range from transmission problems to windshield wiper motor failure and excessive oil consumption. While some problems can be resolved with simple repairs, others may require more extensive work or even replacement of major components. Regular maintenance and inspections can help identify these issues early, potentially saving owners from more significant repair costs down the line.
