88-98 GM 1500 P/U LS Swap Radiator w/Fans

The Cold Case Radiators 88-98 GM 1500 P/U LS Swap Radiator with Fans (GMT580SK) is a direct-fit cooling solution engineered specifically for LS engine swaps into first-generation C/K 1500 trucks. This all-aluminum radiator delivers efficient heat rejection for modern LS powerplants in classic GM truck chassis, combining OEM-quality construction with the thermal capacity demanded by higher-output swap applications. The integrated dual-fan setup eliminates the need for separate fan sourcing and mounting fabrication.

Core dimensions measure 33.85 inches wide by 20.4 inches tall with a 3-inch depth, positioning this unit to fit within the original radiator support with minimal modification. Passenger-side inlet and outlet configurations match standard LS cooling system plumbing, reducing custom hose routing requirements. The polished aluminum finish provides both corrosion resistance and an appearance that complements engine bay aesthetics on display or street trucks. At 41 pounds complete with fans, the assembly maintains weight distribution while delivering the cooling duty required for sustained highway speeds and performance driving.

This radiator is built for owners performing LS engine swaps into 1988–1998 GM C/K full-size trucks who need a bolt-in cooling solution that doesn't compromise underhood clearance or require extensive custom fabrication. Whether building a restomod for weekend cruising or a more serious power upgrade, this unit handles the thermal load without the hassle of aftermarket sourcing and adapter engineering. Cold Case Radiators' reputation in swap-market cooling makes this a trusted component for builders prioritizing reliability and fit-and-function accuracy.
