Pioneer Automotive Engine Expansion Plug Kit

The Pioneer Automotive Engine Expansion Plug Kit line gives engine builders and rebuilders a dependable way to replace freeze plugs (also called core plugs, welch plugs or engine expansion plugs). These plugs seal the casting holes in the engine block and cylinder head. Fresh plugs help keep coolant and oil where they belong during an engine rebuild or when old plugs show corrosion or leaks.

Key Features:

• Multiple materials available: Pioneer offers expansion plugs in brass, steel, stainless steel and threaded styles to suit different applications and corrosion-resistance needs.
• Steel plugs: Made from fine-grained, cold-rolled steel for lasting strength, with zinc plating for corrosion resistance.
• Stainless steel plugs: Give steel-plug performance with better corrosion resistance where the application calls for it.
• Brass plugs: Solid brass construction for the best corrosion resistance.
• Application-specific kits: Kits are put together for particular engine families, so the plugs are matched to the block.
• Made in the USA: Pioneer Automotive Industries is based in Meridian, Mississippi.

Pioneer Automotive Industries supplies a broad range of aftermarket engine and drivetrain parts. Choose the kit that matches your engine and preferred material for a clean, leak-free seal on your next rebuild or cooling system repair.
