Pioneer Automotive PE130B Engine Expansion Plug Kit

The Pioneer Automotive PE130B is a complete engine expansion plug kit — also commonly known as a freeze plug kit or core plug kit — designed to seal the coolant passages in your engine block and cylinder head. These plugs are installed at the factory to close off the casting holes left during the engine manufacturing process and play a critical role in maintaining a leak-free cooling system.

Key Features:

Pioneer's expansion plug kits are a go-to solution for professional rebuilders and DIY mechanics alike. Replacing worn or corroded freeze plugs during an engine rebuild helps prevent coolant leaks and overheating, protecting the longevity of the engine. Always refer to your vehicle's service manual for proper installation torque and procedure.
