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 1985 Gmc C35 problems

The GMC C35 model from 1985 is a part of the third-generation, square-body trucks produced by General Motors, which were a significant departure from the company's previous efforts. These trucks featured squared-off front and rear fascias, subtle body contours honed by wind-tunnel testing, a more accommodating and ergonomic interior, and even an available crew-cab body. The following are some of the common problems reported by owners of the GMC C35 from 1985.

Dash Frame Issues: The dash frame of the 1984-1987 Chevy and GMC C/K Squarebody Trucks, including Blazer, Jimmy, and Suburban models, is known to have issues. The dash frame is a crucial structural component that provides stability and support to the dashboard, ensuring the longevity and integrity of the vehicle's interior. However, the dash frames in these models can sag, warp, or misalign over time, leading to potential problems with dashboard components such as gauges, controls, and vents.
Suspension and Steering Components: Suspension and steering components in these vehicles can wear out or fail, leading to issues with handling and ride quality. Components such as bushings, ball joints, and tie rod ends can wear out, leading to excessive play in the suspension and steering systems. This can result in poor handling, vibrations, and uneven tire wear.
Braking System Issues: The braking system in these vehicles can also experience issues, including worn-out brake pads, rotors, and drums. Additionally, the brake lines and hoses can deteriorate over time, leading to leaks and reduced braking performance.
Engine and Transmission Problems: The engines and transmissions in these vehicles can experience issues such as worn-out clutch assemblies, leaking seals, and worn-out gears. These issues can lead to reduced performance, increased fuel consumption, and even complete failure of the powertrain.
Electrical System Issues: The electrical system in these vehicles can experience issues such as blown fuses, corroded connectors, and faulty switches. These issues can lead to problems with lighting, power windows, and other electrical systems in the vehicle.
Body and Trim Issues: The body and trim of these vehicles can experience issues such as rust, dents, and scratches. These issues can lead to reduced aesthetic appeal and even structural integrity issues in extreme cases.

It is important to note that these issues are common in many vehicles of this age and are not exclusive to the GMC C35 model from 1985. Regular maintenance and inspections can help prevent or mitigate these issues, ensuring the longevity and reliability of the vehicle.
