1991 Chevrolet K25 problems
The third generation of the C/K series is a range of trucks that was manufactured by General Motors from the 1973 to 1991 model years. Serving as the replacement for the "Action Line" C/K trucks, GM designated the generation under "Rounded Line" moniker. Again offered as a two-door pickup truck and chassis cab, the Rounded Line trucks marked the introduction of a four-door cab configuration.
Marketed under the Chevrolet and GMC brands, the Rounded Line C/K chassis also served as the basis of GM full-size SUVs, including the Chevrolet/GMC Suburban wagon and the off-road oriented Chevrolet K5 Blazer/GMC Jimmy. The generation also shared body commonality with GM medium-duty commercial trucks.
In early 1987, GM introduced the 1988 fourth-generation C/K to replace the Rounded Line generation, with the company beginning a multi-year transition between the two generations. To eliminate model overlap, the Rounded Line C/K was renamed the R/V series, which remained as a basis for full-size SUVs and heavier-duty pickup trucks. After an 18-year production run (exceeded only in longevity by the Dodge D/W-series/Ram pickup and the Jeep Gladiator/Pickup), the Rounded Line generation was retired after the 1991 model year.
From 1972 to 1991, General Motors produced the Rounded Line C/K (later R/V) series in multiple facilities across the United States and Canada. In South America, the model line was produced in Argentina and Brazil, ending in 1997.

Common 1991 Chevrolet K25 problems
The 1991 Chevrolet K25 is a popular choice among truck enthusiasts due to its robust design and versatile capabilities. However, like any other vehicle, it is not immune to certain problems that have been reported by its owners. Here are some of the common issues found in the 1991 Chevrolet K25, based on the search results:
- Body and chassis grounds: There may be no immediate or apparent symptoms of bad body or chassis grounds on the K25, but there may be odd electrical problems like the engine not starting or the dash lights flickering. The grounds tend to break and corrode, and this can cause electricity to ground at other parts like the bolts. While this can work temporarily, over time it can cause issues with electrical components. Repairing the ground strap by installing a new ground strap close to the area on the backside of the engine and installing the wire to the chassis can help resolve this issue.
- Door pins and bushings: The doors can sag on the K25 when the pins and bushings wear out. The pins and bushings are in the door jamb. To replace the bushings, the spring will need to be removed from the door check. A special compressor tool is needed to reinstall the spring. This issue can be resolved by replacing the pins and bushings, which may require the assistance of a professional.
- Engine oil leaks: Engine oil leaks are another common problem reported by K25 owners. These leaks can occur due to various reasons, such as worn-out gaskets, damaged oil pans, or loose oil drain plugs. Regular maintenance and inspections can help identify and address these issues before they become severe.
- Tail light problems: Tail light problems, such as tail lights not working or flickering, are also reported by K25 owners. This issue can be caused by a faulty tail light bulb, a blown fuse, or a problem with the wiring. Regular inspections and maintenance can help identify and address these issues.
In conclusion, while the 1991 Chevrolet K25 is a reliable and capable vehicle, it is not immune to certain problems that have been reported by its owners. Regular maintenance and inspections can help identify and address these issues before they become severe.
