Warning Signs of a Bad Timing Belt
The car's timing belt synchronizes the crankshaft and camshaft to ensure that the engine's valves open and close at the right time for optimal combustion. If a timing belt is bad or failing, it can lead to severe engine damage and thousands of dollars in repairs or replacements. Here are the signs to watch out for:
Ticking or Clicking Noise
A timing belt that is starting to wear out may create a ticking or clicking sound as it moves around the tensioner and pulleys.
Difficulty Starting the Engine
If the belt is damaged, the engine may not start at all or have difficulty doing so.
Visible Cracks or Damage
Any visible physical signs of cracks or damage are indicators that the belt needs to be replaced soon.
