1991 Chevrolet K10 problems
The Chevrolet C/K is a series of trucks that was manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series (later the Dodge Ram pickup).
Used for both the model branding and the internal model code, "C" denoted two-wheel drive, while "K" denoted four-wheel drive. Four generations of the C/K series were produced, including the GM monikered second-generation "Action Line" and third-generation "Rounded Line" vehicles (colloquially aka Square-Body trucks). For the fourth-generation (colloquially also known as OBS trucks), Chevrolet kept using the C/K designation while GMC revised its branding, changing to a singular GMC Sierra nameplate (C/K remained as an internal model code).
For South America, the model line was manufactured by General Motors de Argentina from 1960 to 1978, Sevel Argentina from 1986 to 1991, and General Motors Brazil, who produced versions of the model line for Brazil, Argentina, and Chile from 1964 to 2001.
As GM entered the 1990s, the company revised its truck ranges, replacing the medium-duty C/K trucks with the Chevrolet Kodiak/GMC TopKick for 1990. For 1999, GM replaced the fourth-generation C/K pickup trucks with an all-new model line; in line with GMC, Chevrolet dropped the C/K nameplate (in favor of a singular Chevrolet Silverado nameplate). Initially marketed with its successor, the final C/K pickup trucks were produced for the 2000 model year. From 2001 to 2002, the final vehicles of the C/K model line were medium-duty chassis cab trucks.

Common 1991 Chevrolet K10 problems
The 1991 Chevrolet K10, like any other vehicle, can experience various issues over time. Here are some common problems reported by owners of this model:
- Windshield wiper motor failure: The windshield wipers on models made between 1990 and 1999 may stop working intermittently due to a defective wiper motor. This issue can be caused by a faulty wiper motor control board, which can cause the wipers to stop working, fail to turn on, keep running after being turned off, or only work on one speed setting. A buzzing noise from the motor control box when the wipers are not working is a common symptom of this problem. As a temporary fix, lightly tapping on the control box can sometimes restore functionality. However, replacing the wiper motor control board is recommended for a more permanent solution.
- Coolant leaks or oil leaks from intake manifold gaskets: Coolant or oil leaks from intake manifold gaskets can be a problem in the 1991 Chevrolet K10. These leaks can cause the engine to run poorly or overheat, and can be caused by worn or damaged gaskets. Replacing the gaskets is the recommended solution for this issue, which can cost approximately $1,000 to have done by a mechanic.
- Restricted secondary air injection valves: The secondary air injection check valves in the 1991 Chevrolet K10 can become restricted, leading to reduced airflow and causing the check engine light to come on. Fixing this problem requires replacing the check valves. It is recommended to replace both valves, even if only one is showing a fault code, to avoid having the other one fail in the future. This issue typically occurs at around 133,000 miles and can cost between $100 and $150 per valve.
- Failed steering wheel position sensor: A failed steering wheel position sensor can cause a service stability message to appear in the 1991 Chevrolet K10. This issue can occur intermittently or more regularly, such as every time the vehicle is started or the wheel is turned. Replacing the sensor, which can cost between $200 and $300, is the recommended solution for this problem. This issue typically occurs at around 90,000 miles.
- Cooling problems with big block engines: Cooling problems can occur in the 1991 Chevrolet K10, particularly with big block engines. These issues can be caused by a variety of factors, including a faulty fan clutch or an incorrectly adjusted distributor advance curve. Adjusting the distributor advance curve and checking the fan clutch can help improve cooling performance and prevent overheating.
In summary, the 1991 Chevrolet K10 can experience various issues, including electrical problems, windshield wiper motor failure, coolant or oil leaks from intake manifold gaskets, restricted secondary air injection valves, failed steering wheel position sensors, and cooling problems with big block engines. Addressing these issues promptly can help prevent further damage and maintain the vehicle's performance and reliability.
