Product Details

The Dorman 550-023 is a concave steel cup expansion plug designed for reliable sealing of engine block and cylinder head core holes. This freeze plug measures 1-5/8 inches in diameter with a height of 1.620 inches, providing precise fitment for proper engine sealing applications.

Key Features:

  • Concave steel cup design for secure installation and dependable sealing
  • 1-5/8 inch diameter for specific engine block applications
  • 1.620 inch height dimension ensures proper depth coverage
  • Durable steel construction resists corrosion and withstands engine temperatures
  • Direct replacement for worn or corroded freeze plugs

Expansion plugs, commonly known as freeze plugs or core plugs, are essential components that seal the core holes left during the engine block casting process. This Dorman freeze plug helps prevent coolant leaks and maintains proper engine cooling system integrity. The concave design allows for proper expansion during installation, creating a tight seal against the block.
