Review on 🛠️ Dorman 555-030 Steel Cup Expansion Plug - 1.625 In., 0.500 Height, Pack of 10 - Improved SEO by Chris Walker

These plugs will fit a 1995 GM 4.3L V6 262 engine block with the correct preload and will withstand the force of being driven into the holes. I used Permatex thread sealant on the mating surfaces. I needed eight connectors for the block so two were left over. For reference, the camshaft and balancer shaft holes on the back of the block fit into a larger spreader plug.
