The Chevrolet K20 looked like a very muscular and powerful 4-wheel-drive automobile since its introduction in the 1960s. It was equipped with sturdy car components from the interior to the exterior, and its engine performance was also deemed to be satisfying among its drivers. However, all tough-looking automobiles still have even slight weaknesses in them. The Chevrolet K20 is not an exception to this fact. The following are some of the common problems found in this pickup truck:
Reported problems with the service brakes of the Chevrolet Express 3500 included improperly positioned brake pedal push rod retainers. Now, every component in the braking system is vital. Damages or defects in these parts could cause accidents or collisions. When these rod retainers fail, the stop lamp switch and the brake booster push rod might disconnect from the brake pedal. Consequently, loss of brake operation would be apparent. A recall was done to correct this defect. Express 3500 vehicles were inspected, and the rod retainers were fixed in such cases when they were in the wrong position.
The gasket in the oil filter of the Chevrolet Express 3500 tend to become supple over time especially under high temperature and extreme pressure. Because of this defect, engine oil might seep out. It is very dangerous, since this leak could result into a fire. As a response to this concern by Express 3500 owners, Chevrolet recalled the affected vehicles to replace the defective oil filters. This recall happened sometime in 2007.
It was discovered that the bolts attaching the seat recliner to the seat frame had a tendency to become loose or fractured. As a result, this damage could make the seat recline all of a sudden. It may seem like a funny scenario; but if it happens on the driver's seat while the car is running, it could mean a serious accident. Chevrolet recalled the damaged vehicles. Washers were installed between the seat recliner and seat frame, and new retaining bolts were torqued to a higher specification. All the fabric and foam, which were located between the recliner assembly and the seat frame, were taken out as well.
