82-92 F-Body LS Swap Radiator

The 82-92 F-Body LS Swap Radiator (model LMP590-5) is the backbone of any serious LS engine conversion in second-generation Camaro, Firebird, or Trans Am platforms. When swapping a modern LS powerplant into a classic F-body, cooling becomes non-negotiable—stock radiators simply cannot handle the sustained heat output of a high-revving LS engine paired with modern performance demands. This purpose-built radiator solves that problem, engineered specifically for the tight engine bay constraints of 1982–1992 F-bodies while delivering the thermal capacity modern LS mills require.

This radiator's design accounts for the unique mounting points and plumbing geometry of F-body LS swaps, eliminating the guesswork and custom fabrication that plague generic universal coolers. The aluminum core construction maximizes heat dissipation efficiency while the compact 23 × 8 × 35-inch footprint fits cleanly within the factory envelope—critical when working with vintage sheet metal and modern engine bay real estate. At 19.85 lbs, the unit strikes a balance between substantial cooling capacity and weight savings, a consideration that resonates with both street and track-focused builds where every pound matters for handling and performance.

LS swap enthusiasts undertaking F-body restorations benefit immediately from purpose-engineered cooling that eliminates mid-range heat soak and transmission fluid overheating during spirited driving or summer cruising. Whether you're building a 350-hp street machine or a 500+ hp weekend warrior, this radiator accommodates both naturally aspirated and boosted applications without requiring extensive radiator shroud modifications or custom inlet/outlet plumbing. Installation is straightforward for builders with intermediate mechanical skill; the radiator's geometry aligns with both early-style and late-model LS pump configurations common in F-body swaps, making it a drop-in solution for most conversion harnesses and hose routing schemes.
