70-85 Jeep CJ Radiator

The 70-85 Jeep CJ Radiator from Cold Case Radiators is engineered for owners restoring or maintaining first-generation Jeep CJ models who demand reliable cooling performance in demanding conditions. Whether you're running trails, towing gear across rough terrain, or simply keeping your classic CJ running cool under sustained load, this aluminum radiator handles the heat that original cast-iron units struggle with. Built for serious off-road enthusiasts and restoration builders, this unit replaces factory cooling systems that have degraded or failed after decades of service.

Constructed from high-efficiency aluminum with a polished finish, the 70-85 Jeep CJ Radiator features a passenger-side inlet and driver-side outlet configuration that matches factory mounting and plumbing without requiring extensive modification. Aluminum construction provides superior heat dissipation compared to traditional copper-brass radiators, while the polished aesthetic complements restored engine bays and adds visual appeal. The compact core design fits within original dimensional constraints—measuring 26.85 inches wide by 20.5 inches tall by 3 inches deep—ensuring proper fitment in the tight CJ engine compartment without interfering with steering or accessory belts.

CJ owners tackling long expeditions, heavy hauling, or high-temperature environments will experience noticeably improved cooling compared to original radiators, reducing the risk of overheating during peak summer months or extended operation in stop-and-go trail conditions. Installation requires standard hand tools and basic mechanical skill; verify that your inlet and outlet hose routing matches the passenger-side inlet/driver-side outlet layout before ordering. This radiator is compatible with 1970–1985 Jeep Wrangler CJ models and serves as both a direct replacement for failed units and an upgrade for builders prioritizing reliable thermal management.
