Seal the casting core openings in your engine with the Pioneer Automotive Industries Expansion Plug Kit (PN PE-183, also written PE183). It installs as a direct-fit replacement on the L4-2.0L in vehicles like the 1987-1989 Chevrolet Beretta, 1985-1989 Chevrolet Cavalier, 1985-1989 Buick Skyhawk, 1987-1989 Pontiac Grand Am and 1986-1994 Pontiac Sunbird — see the Buyer's Guide tab for the full list of applications.
Expansion plugs fill the core holes left in the engine block and cylinder head castings during manufacturing. Over time these plugs can corrode and begin to seep, so fitting a fresh set is a routine step during an engine rebuild or reseal.

How do I know an expansion plug needs replacing?
Signs include weeping, staining, or a rust-through leak at an old plug. Diagnose the source before replacing, since a leak can also come from a gasket or nearby seal.

Expansion plugs are driven into their bores rather than bolted in. Follow the vehicle service procedure for the correct seating and any recommended sealant.
