Seal the cast core openings in your engine block and cylinder head with the Pioneer Automotive Industries Engine Expansion Plug Kit PE-145-BR. It drops in as a direct-fit replacement kit for the 1972-1974 Chevrolet LUV Pickup and the 1975 Chevrolet LUV, both with the L4-1.8L engine, giving you the expansion plugs needed to close off the casting core holes left in the engine during manufacturing.
Expansion plugs — also called freeze or core plugs — are driven (press-fit) into their core openings; they aren't threaded or bolted in. Over time they can corrode and seep, so if a rusted or leaking plug is the problem, replacing it during a rebuild or repair helps re-establish a tight seal at the core hole.
Manufacturer part number PE-145-BR.
