Timing Belt Diagnosis and Repair Tips

Honda Accords with a timing belt have interference engines. If the timing belt fails, the valves will contact the pistons and cause engine damage. The following conditions can lead to timing belt failure and possible engine damage:

  • Timing belt age
  • Timing belt wear
  • Timing belt tensioner wear or failure

The timing belt can wear or deteriorate from either age or high mileage. The timing belt teeth can wear from friction. The rubber compound of the timing belt can also become stiff and crack over time. It’s vital to recognize timing belt issues early before engine damage occurs. A failing timing belt tensioner can cause engine noise and poor performance. Preventative maintenance and recognition of timing belt failure symptoms can help avoid more costly engine repairs.

Why Do Honda Accords Have Timing Belt Problems?

Honda Accord engines can be susceptible to timing belt tensioner failure. A spring inside the tensioner can eventually fail, causing the timing belt to slip and damage the engine. Typically, timing belt and tensioner failures occur with high mileage and age. Water pump life can be affected by timing belt or cooling system issues. Inspect the timing belt at recommended internals and perform scheduled cooling system maintenance. Always replace the timing belt tensioner and water pump when servicing the timing belt.
