LowPricedAutoParts Brass Freeze Plug Kit (Expansion/Core Plugs) - Fits Chevrolet GMC Hummer AM General 6.2L 6.5L Diesel V8 Engines 1982-2004

Prevent coolant leaks and protect your GM 6.2L or 6.5L diesel V8 from freeze-related damage with this premium brass freeze plug kit from LowPricedAutoParts – a complete set tailored for the 6.2L/379 and 6.5L/395 OHV V8 diesel engines (naturally aspirated or turbocharged applications; code L65; DIESEL) from 1982–2004. This high-quality kit fits a wide range of models including Blazer, C/K-Series trucks, Express/Savana vans, G-Series vans, H1/Hummer, Jimmy, Suburban, Tahoe, Yukon, and more – essential for engine rebuilds, refreshes, or replacing worn/corroded plugs in these rugged, torque-heavy diesels that powered work trucks, SUVs, vans, and heavy-duty vehicles with exceptional durability and pulling power. The kit supplies all necessary premium brass freeze plugs (also known as core plugs or expansion plugs) to seal block and head casting holes, offering superior corrosion resistance over steel for dependable coolant containment and protection against cracking in cold weather or demanding conditions. Matched to the 6.2L/6.5L diesel 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 keep your truck or van running strong with restored efficiency, massive torque, and legendary diesel reliability for towing, hauling, fleet work, or off-road duty. This is not a universal kit for mismatched engines or severely damaged blocks without inspection – professional measurement of plug holes, 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.
