Do I Need a Timing Belt Replacement?

Your vehicle's timing belt is a fundamental part of the engine that often gets overlooked. This rubbery piece is responsible for synchronizing and regulating the rotation of the crankshaft and camshaft. Without this pivotal part, the engine valves would not open and close at the proper time. The belt has teeth or ridges to provide consistent movement. If the timing is damaged or the timing belt connection is insufficient, it could spell disaster for your engine. For instance, the pistons can hit the valves, causing irreversible harm to the engine. The timing belt must be correctly fitted and be kept in good condition.


Common Causes of Timing Belt Failure

There are various ways a timing belt can fail. Those include:

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

Signs That a Timing Belt Needs Replacement

There are several signs that may indicate that your timing belt needs replacement. Here's what to look for:

  • A high-pitched noise coming from under the hood
  • Visible indications of belt damage—cracks, glazing, and dirt build-up
  • Sluggish engine starts or a failure to start engine

The industry standard suggests that you replace your timing belt after 90,000-100,000 miles. However, these numbers are simply an approximation. Next time you are in for a maintenance service, such as an oil change, ask your technician to inspect your timing belt.
