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 1989 Gmc K25 problems

The GMC K25 1989, also known as the 4th Gen Chevy Truck, is prone to several common problems based on complaints from owners of this car. Here are the details of these issues:

Body and Chassis Grounds: There may be no immediate or apparent symptoms of bad body or chassis grounds on the 4th gen Chevy truck, 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. Repair 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.

Door Pins and Bushings: The doors can sag on the C/K 1500 truck 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. The steps include having an assistant hold the door or place a floor jack underneath the door to support it, and then popping the pins and bushings out with a chisel and a hammer.

Engine Oil Leaks: As vehicles age, it’s common for parts to corrode and wear over time and leak, like the oil pan gasket. A lot of 4th gen Chevy trucks experience engine oil leaks, which can be caused by a variety of factors, including worn-out gaskets, loose bolts, or damaged oil pans. It's essential to diagnose and fix the underlying issue to prevent further damage to the engine.

Tail Light Problems: Tail light problems are also common in the 4th Gen Chevy Truck. The tail light assembly may have issues with wiring, bulbs, or connectors, causing the tail lights to malfunction. It's essential to diagnose and fix the underlying issue to prevent safety hazards on the road.

In conclusion, these are some of the most common problems with the GMC K25 1989, based on complaints from owners of this car. Regular maintenance and timely repairs can help prevent these issues and ensure the longevity of the vehicle.
