Product Details

The Federal Mogul E448X is a precision-engineered engine expansion plug, commonly referred to as a freeze plug or core plug. Designed to seal the casting holes left in engine blocks and cylinder heads during the manufacturing process, this plug provides a reliable barrier against coolant leaks and helps maintain proper engine cooling system integrity.

Federal-Mogul, a trusted name in engine sealing and repair components, manufactures this expansion plug to meet or exceed OEM specifications. The E448X is built to withstand the thermal cycling, pressure, and chemical exposure typical of modern engine coolant systems.

Key Features:

  • OEM-quality construction for a reliable, long-lasting seal
  • Engineered to meet or exceed original equipment specifications
  • Resists corrosion and thermal stress from engine heat cycling
  • Designed for straightforward installation using standard expansion plug tools
  • Compatible with standard coolant formulations

The Federal Mogul E448X expansion plug is a dependable choice for engine rebuilds, coolant leak repairs, or preventative maintenance. Replacing worn or corroded freeze plugs during an engine overhaul is a best practice to prevent future coolant loss and costly engine damage.
