Reseal the casting and core openings in your engine with the Pioneer Automotive Industries Engine Expansion Plug Kit (PE-182-B), a direct-fit replacement set for the 1979-1980 Cadillac Eldorado and the 1978-1980 Cadillac Seville. Expansion plugs — also called core plugs — fill the openings left in the engine casting during manufacturing, and after years of service they can corrode and begin to seep. This kit supplies fresh plugs so those openings can be sealed again.
Signs a plug may need replacing: dampness, staining, or seepage around a core/casting opening on the block or head. Diagnose the source of any leak before replacing, as seepage can also come from nearby gaskets or seals.
Fitment: 1979-1980 Cadillac Eldorado; 1978-1980 Cadillac Seville.
Interchange: Manufacturer part number PE-182-B (also PE182B).
