Route 2

Match the old plug

Use the SMART-O® Gauge, head marking or thread size when vehicle data is unclear.

The physical gauge is the fastest way to confirm thread diameter and pitch when the vehicle database is unclear, modified or incomplete.

  1. Remove and clean the existing oil drain plug.
  2. Slot the plug into the SMART-O® Gauge.
  3. Match diameter, pitch and head marking.
  4. Order the corresponding SMART-O® plug and washer pack.

Already know your thread size?

Skip the vehicle lookup and order by thread size, head marking or replenishment pack. This route is built for service bays that already know the common sizes they use every week.
