  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.
