Question

Accepted Answer

The Volkswagen Passat CC should have its timing belt changed every 105,000 miles. This belt is responsible for connecting the camshaft to the crankshaft and is located at the front of the engine where it can be affected by the weather. As it ages, the belt may dry out, crack, and eventually break. Additionally, faulty pulley bearings can create friction, generating heat that may lead to belt failure. Proper alignment of the timing belt is essential for synchronizing piston and valve movements. If the timing belt becomes misaligned, even slightly, it can negatively impact engine performance. Signs of a timing belt issue include difficulty starting the car, rough idling, and a significant decrease in fuel efficiency.
