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 1993 Gmc C10 problems

The 1993 GMC C10, also known as the GMC Sierra, is a popular pickup truck known for its reliability and versatility. However, like any vehicle, it is not immune to common problems that can arise over time. Here are some of the most frequently reported issues with the 1993 GMC C10, based on complaints from owners:

Alternator Failure: Another common issue with the 1993 GMC C10 is alternator failure. This problem can cause the battery to die, resulting in a no-start condition. It can also cause abnormal noises, such as whining or grinding, and may or may not trigger a dash warning light. Replacing the alternator is the only solution to this problem, which can cost between $300 and $400 on average.

Internal Distributor Faults: Some 1993 GMC C10 owners have reported internal faults in the distributor, which can cause the engine to run roughly or stall. This problem is less common than some of the others on this list, but it can be caused by worn-out or damaged parts inside the distributor. Replacing or overhauling the internal distributor is the only way to fix this problem, which can occur at around 130,000 miles.

Windshield Wiper Motor Component Failure: Models made between 1990 and 1999, including the 1993 GMC C10, may experience intermittent windshield wiper failure due to a defective wiper motor control board. This problem can cause the wipers to stop working, fail to turn on, or keep running after being turned off. It can also cause the wipers to only work on one speed setting. A buzzing sound from the motor control box can indicate this problem. Replacing the wiper motor control board is the only permanent solution, but lightly tapping on the control box can provide a temporary fix.

Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: The intake manifold gaskets in 1988 to 1998 GMC C10 trucks can develop external engine oil or coolant leaks, which can cause coolant to mix with engine oil and damage the engine. This problem most commonly occurs at around 175,000 miles and can be fixed by replacing the intake manifold gasket, which can cost between $300 and $450.

Front Wheel Speed Sensor Failure: The front wheel speed sensors or anti-lock brake system (ABS) sensors in the 1993 GMC C10 can fail, causing the ABS warning light to turn on or activate erratically. This problem can cause the ABS to activate on dry roads at slow speeds, making the vehicle difficult to control. Replacing the faulty sensor is the only solution to this problem.

Failed Crankshaft Position Sensor: Some 1993 GMC C10 owners have reported issues with the crankshaft position sensor, which can cause the engine to misfire or fail to start. Replacing the sensor can solve this problem, but it is essential to ensure that the sensor is the root cause of the issue before replacing it.

Failed Steering Wheel Position Sensor: The steering wheel position sensor in the 1993 GMC C10 can fail, causing a service stability message to appear on the dashboard. This problem can occur intermittently or consistently and can cause the steering wheel to feel unstable or unresponsive. Replacing the sensor can solve this problem, which typically occurs around 90,000 miles.

Fuel Pump Failure: The fuel pump in the 1993 GMC C10 can fail, causing the engine to misfire or fail to start. Replacing the fuel pump can solve this problem, but it is essential to ensure that the fuel filter and strainer are also in good condition before replacing the pump.

Radiator Overheating: Some 1993 GMC C10 owners have reported issues with the radiator overheating, which can cause the engine to run hot and potentially damage the engine. Replacing the radiator and hoses can solve this problem, but it is essential to ensure that the cooling system is properly maintained and that the engine is not running low on coolant.
