1979 Gmc C2500 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.

1979 GMC C2500: Common Problems and Complaints
1. Electrical Issues
One of the common problems reported by GMC C2500 1979 owners is electrical issues, particularly related to the starter. In some cases, the starter won't start or make any sound, even after installing a new starter switch, checking the battery, fuses, and wires. This issue can be frustrating, especially when the truck won't start after sitting for a while, only to start later.
2. Rusting and Buckling
Early square-body C10 trucks, including the 1979 GMC C2500, were prone to rusting, particularly in the lower rear section of the front fenders and above the wheelwells on Fleetside trucks. This issue was more prevalent in California, where rust began to appear as early as 1976.
3. Weak Frames
The early standard-equipment square-body C10s had weak frames that twisted, particularly in the shortbed or longbed form with the F44 package. This package featured heavier-duty framerails and crossmembers, which addressed the issue.
4. Fusible Link Failure
Another electrical issue reported by GMC C2500 1979 owners is the failure of the fusible link. This issue can cause the vehicle to shut off completely, with all accessories, including the radio, heater, wipers, and gauges, becoming dead.
5. Engine Conversion Issues
Some GMC C2500 1979 owners reported massive problems with their vehicles, particularly those that were converted from diesel to gasoline engines. These issues can include engine breakdowns and other mechanical problems.
6. Oil Cooler Hose Stripping
Some GMC C2500 1979 owners reported issues with the oil cooler hoses, including stripping of the lower fitting on the radiator. This issue can cause high oil pressure indications and require bypassing or reconnecting the hoses.
7. Heater Issues
Some GMC C2500 1979 owners reported issues with the heater, including difficulty getting the heat off the floor and inability to blow on the mid-range dash vents or on the defrost mode.
These are some of the common problems reported by GMC C2500 1979 owners. While these issues can be frustrating, they are not uncommon for vehicles of this age and can often be addressed with proper maintenance and repairs.
