If you are driving a Volkswagen with a V belt issue, you are at risk of several serious problems. First, the V belt is the main component that helps control the engine’s timing. Without proper tension, the timing can slip. This can lead to premature wear and tear on the engine, or even catastrophic engine failure. Additionally, not having the V belt in top condition can lead to other components in the engine, from the alternator to the coolant system, to not function properly. If any of these components fail, it can cause more damage to the engine, or to other parts of the vehicle. Finally, if the timing is off, the fuel efficiency of the car can decrease, meaning that you will be consuming more fuel and spending more on fuel costs.
