Review on Dorman 555 097 Steel Expansion Plug by Michael Gutierrez

Revainrating 1 out of 5

Non 25mm Plug For Engine Parts

This plug actually fits a 1 inch hole which is exactly 25.4mm. Therefore it will not fit in a 25mm hole. If you want it to be a 1 inch freeze plug, this one will be fine. But it's advertised as 25mm and it's not, hence my low rating. If they sold it as a 1 inch plug I would give it 5 stars.

Pros
  • Automotive
Cons
  • Expandable
