Is It Time for a New Timing Belt?

Belts and hoses are some of the most economical parts of an engine. However, if they begin to fail or tear, they can lead to some relatively severe damages. 


In particular, your car's timing belt is an integral part of the engine because of its job. It is responsible for synchronizing and coordinating the rotation of the crankshaft and camshaft. Without this movement, the engine valves would not open and close at the appropriate times for operation. The belt uses teeth to provide consistent coordination. If the timing is off or the timing belt connection is weak, it could be disastrous for your engine. For example, the pistons can strike the valves, causing damage to the engine. The timing belt must be correctly installed and maintain a good condition.


Common Causes of Timing Belt Failure

There are several different ways that a timing belt can fail. These include:

  • Stripped teeth on the strap
  • Unraveling of the belt's fiber cores
  • Belt breakage (uncommon)
  • Incorrect belt tension—too tight or too loose

Signs That You Need a Timing Belt Replacement

There are a few symptoms that indicate that your timing belt needs attention. Here's what to look for:

  • A high-pitched sound coming from the engine
  • Visual signs of belt damage—cracks, glazing, and dirt build-up
  • Slow or sluggish engine starts, or a failure to start

Most manufacturers suggest that you change the belt after 90,000-100,000 miles. However, those numbers are simply an estimate. Next time you are due for a maintenance service, feel free to ask your mechanic to inspect your timing belt.
