Timing Belt replacement intervals

  • Where possible the recommend intervals have been complied from vehicle manufactures information. In a few insances no recommendation has been made by the manufacturer and the decision to replace the belt must be made from the evidence of a through examination of the condition of the existing belt.
  • Apart from the visible condition of the belt, which is explained fully in the general Instructions/Toothed Timing Belt section, there are several other factors which must be considered when ccecking a timing belt.
  1. Is the belt an original or a replacement?
  2. When was the belt last replaced and  was it at the correct mileage?
  3. Is the service history of the vehicle known?
  4. Has the vehicle been operated under arduous conditions whish might warrant a shorter replacement interval?
  5. Is the general condition of other components in the camshaft drive , such as the tensioner , pulleys, and other ancillary components driven by the timing belt, typically the water pump , sound enough to ensure thet the life of the replacement belt will not be affected?
  6. If the condition of the existing belt appears good, can you be satisfied that the belt will not fail before the next check or service is due?
  7. If the belt does fail, have you considered the consequences? if the engine is an INTERFERENCE type then considerable expensive damage may well be the result.
  8. The cost of replacing a belt as part of a routine service could be as little as 5 to 10% of the repair cost following a belt failure.Make sure your customer is aware of the consequences.
  9. If in doubt about the condition of the belt - RENEW it.
  10. Refer to the Toothed Timing Belts/Service Replacement section for further information relating to arduous or adverse
  11. operating condition, inspection and service replacement.
