Replacement Interval Guide

  • Vauxhall recommend replacement as follows:
  • →96MY – replacement every 40,000 miles or 4 years, whichever occurs first.
  • 97-98MY – replacement every 80,000 miles or 8 years, whichever occurs first.
  • 99MY→ – replacement every 80,000 miles or 8 years, whichever occurs first (tensioner pulley must also be replaced).
  • Meriva – replacement every 80,000 miles or 8 years (tensioner pulley must also be replaced).
  • The previous use and service history of the vehicle must always be taken into account.

Check For Engine Damage
