Prevent coolant leaks and protect your GM 3.8L 3800 V6 from freeze-related damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set tailored for the 3.8L/3800 OHV V6 engines (naturally aspirated or supercharged applications; codes L27, L32, L36, L67; GAS) from 1995–2007 (block plugs 1.517" diameter). This high-quality kit fits popular models like Bonneville, Camaro, Firebird, Grand Prix, Impala, LeSabre, Park Avenue, Regal, Riviera, and more – essential for engine rebuilds, refreshes, or replacing worn/corroded plugs in these legendary, torque-rich V6s that powered family sedans, coupes, and performance cars with smooth power, excellent efficiency, and proven reliability. The kit supplies all necessary premium brass freeze plugs (also known as core plugs or expansion plugs) to seal block and head casting holes, including the specified 1.517" block plugs, offering superior corrosion resistance over steel for dependable coolant containment and protection against cracking in cold weather or harsh conditions. Matched to the 3.8L 3800 specs, these plugs deliver a precise, OEM-style fit that minimizes leak risks, maintains cooling system pressure, and promotes long-term engine health. Ideal for addressing age-related failures during overhauls – this set helps revive your vehicle's refined performance, responsive acceleration, and dependable drivability for years of comfortable commuting, highway cruising, or spirited driving. This is not a universal kit for mismatched engines or severely damaged blocks without inspection – professional measurement of plug holes (including 1.517" block plugs), thorough cleaning, and correct installation techniques (with sealants as per GM guidelines) are crucial for a leak-free, distortion-free seal. Always verify hole diameters and drive plugs squarely during assembly. Verify your exact year and application before ordering.
