1991 Chevrolet K20 problems

Common 1991 Chevrolet K20 problems

The Chevrolet K20 1991, like any other vehicle, has its fair share of common problems. Here are some of the most frequently reported issues by owners of this car:

1. Steering shaft knock or clunking noise: Many Chevy Silverado and GMC Sierra drivers, including those with 1991 K20 models, have reported hearing a knock or a clunking noise coming from the steering shaft. This issue may occur due to worn-out components or loose connections in the steering system. The problem may worsen over time and could lead to more severe complications if not addressed promptly.
2. Failed steering wheel position sensor: If you get a service stability message in your Silverado or Sierra, it may be because of a failed steering wheel position sensor. These errors may occur intermittently or more regularly, such as every time you start your truck or turn the wheel. Replacing the sensor, which will cost you about $200 to $300, should fix this issue. This issue could occur at any time, but the average mileage at which it occurs is around 90,000.
3. Windshield wiper motor component failure: The windshield wipers on models made between 1990 and 1999, including the 1991 K20, may stop working intermittently due to a defective wiper motor. If you experience trouble with your windshield wipers, check with a dealer to see if there is a recall on your vehicle. If you have a faulty wiper motor control board, your wipers may, at times, stop working, fail to turn on or keep running after you turn them off. You might also find your wipers only work on one speed setting. When the wipers are not working, you should hear the motor control box buzzing. As a temporary fix to the problem, lightly tap on the control box, and the blades should start working again. For a more permanent fix, replace the wiper motor control board.
4. Coolant leaks or oil leaks from intake manifold gaskets: Older Sierras and Silverados, including the 1991 K20, are known to have issues with coolant leaks or oil leaks from intake manifold gaskets. These leaks can lead to engine overheating or reduced performance. In some cases, the leaks may be caused by worn-out gaskets or damaged seals, which would require replacement.
5. Alternator failure: In older Sierras and Silverados, the alternator may eventually fail, causing the battery to die and, possibly, an abnormal noise to occur. This may or may not cause a dash warning light to come on. If your alternator fails, you will need to replace it, which typically costs around $300 to $400. This problem occurs on average at around 125,000 miles.
6. Internal distributor faults: Numerous drivers have reported that their truck developed internal faults in the distributor, although this problem isn't as common as some of the others on this list. You may hear a squealing noise coming from the distributor, and the issue may cause the engine to run roughly or stall. The check engine light may or may not come on. You'll need to overhaul or replace the internal distributor to correct this problem. Start watching out for internal distributor fault issues at around 130,000 miles.

These are just a few of the common problems reported by Chevrolet K20 1991 owners. Regular maintenance and inspections can help identify and address these issues before they become more severe.
