Aluminum Raditor 77-87 GM P/U LS Engine

The Aluminum Radiator 77-87 GM P/U LS Engine from Cold Case Radiators is designed for vintage GM truck enthusiasts and those undertaking LS engine conversions. This radiator addresses the cooling needs of classic 1977–1987 GM pickups, which often struggle with the heat output of modern LS small-block engines.

Constructed with full-aluminum cores and tanks, this radiator offers superior heat dissipation compared to traditional copper-brass designs. It features optimized tube and fin geometry tailored for LS engine applications, ensuring effective thermal management even under heavy loads or towing conditions.

Builders restoring or restomodding square-body Chevrolet, GMC, or Isuzu pickups will find this radiator particularly beneficial. Its dimensions are designed to fit original mounting points for LS engine swaps, making it a practical choice for those seeking modern cooling efficiency in a classic vehicle.
